Money works differently in communities traditionally excluded from formal banking, which makes designing products that really serve their needs a very different kind of challenge. People who live in the last mile often prefer cash because it’s physical. They can see it, touch it, and access it at any time.

While digital money offers many benefits, such as securely sending money over long distances and accessing new forms of credit, many don’t trust it because the places where they can access digital currency have often been too far away.

In 2017, over 500 million adults lived more than three miles from a financial access point in eight emerging markets studied by the Gates Foundation. This may not sound like much of a barrier, but for those living in the last mile, it means having to close their shops, lose a day of earnings, arrange family care, and pay for travel, which can be time-consuming and difficult, especially during rainy seasons. For low-income people, the inaccessibility of financial services has been a deal-breaker for adopting digital money. On the flip side, banks, telecoms, and other companies struggled to reach these customers because their products were not inclusively designed for them, and their distribution models failed to scale in rural areas.

Amid these myriad challenges, IDEO and the Gates Foundation saw an opportunity to introduce innovative ways to provide access to digital financial services even in the most remote areas of the world. And to make bold new bets: Could we design new digital experiences centered around the financial needs of people in the last mile? What would happen if we mobilized hundreds of actors to develop new ways to address financial access at the last mile? What if we took the most exciting financial innovations that worked in East Africa and piloted them in South Asia—and vice versa?

Working with more than 70 partners, including local startups, corporations, including Google, Unilever, Telenor, Standard Chartered, and BNI, as well as IDEO.org’s Women & Money program, LMM adopted a collaborative, ecosystem approach to drive and scale new digital financial products and systems.

A few of the life-changing innovations launched by LMM and its partners include:

• Finja’s intuitive small-business app that helps micro-merchants in Pakistan access flexible, interest-avoiding Islamic credit  to order products from fast-moving consumer goods companies like Unilever. Finja now serves 45,000 merchants and reaches 10.2 million customers.
  ‍
• Accessing government benefits can be a challenge, especially when it’s through a mobile phone, so IDEO helped Indian startup Haqdarshak develop a robust digital experience for its 52,000 community agents to facilitate access for low-income people. The agent network—70 percent of whom are women—now serves more than 7.6 million families and has unlocked $2.2 billion in social benefits for those who need it most.
  ‍
• Making micro-credit nearly instantaneous was a solution that startup Kuunda offered to financial agents in Tanzania. IDEO helped adapt the product to deliver working capital for merchants in Pakistan. Today, Kuunda continues to grow across markets in Africa, totaling 6.1 million active users and distributing $1.1 billion in loans globally.   

While the LMM program officially concluded in 2024, lessons, tools, and case studies from the program are accessible on IDEO’s Financial Futures website. Those looking to catalyze equity and inclusion in digital financial services for the last mile can consult LMM’s Financial Confidence Playbook, the open-source Digital Confidence Toolkit (created in collaboration with Google), or the Gender Evaluation Framework, among other helpful resources.

Multinational CPGs excel at creating popular, mass-market products for large countries. When they enter smaller countries like Peru, they often parachute their brands onto store shelves and skip consumer product testing altogether, largely relying on brand recognition to drive sales. This oversight presented Alicorp and IDEO with an opportunity: flip the script and invite young Peruvian women to work together with them to create a new hair care brand from scratch. Over the course of a four-year transformational journey, IDEO worked closely with Alicorp, adopting a “learn by doing” approach to foster a culture of innovation, launch a new brand, and drive growth for the company through consumer-centric design.

The collaboration began with an inspirational trip 10,000 miles away to Seoul, South Korea, the epicenter of global beauty trends. To expand their thinking, the Alicorp/IDEO team received K-Pop glow-ups and explored other cutting-edge beauty experiences. They were inspired by the Korean market’s unwavering focus on meeting the particular hair care and skin needs of Korean women.

Back in Peru, the team conducted multiple rounds of in-depth interviews with young women, teenagers, beauty influencers, and experts across the country. They learned about their beauty goals, personal care routines, and “mixto” hair texture. They heard about women’s struggles with regional weather—the Andean region’s extreme dryness versus Lima’s humidity and the city’s hard water. The research revealed that Peruvian women wanted natural products that worked hard, wouldn’t harm their hair, and celebrated what made them unique. They wanted a brand that spoke to them honestly and authentically. That represented and empowered them. That didn’t overpromise, underdeliver, or hold up European and American beauty ideals that didn't resonate with Latin American women like the multinationals did.

Armed with these insights, the Alicorp/IDEO team developed tangible brand prototypes for women to respond to during successive rounds of user research, including in a beauty pop-up store in Lima. The team shared various bottle types, ingredient mixtures, and brand positioning options. Should the new brand’s personality be an outspoken feminist or a gal pal? Au naturel or sophisticated? The iterative feedback cycles informed everything from brand strategy and ingredient recommendations to product line-up, brand and product naming, launch strategy, and digital activations.

The final design, Amarás (“you will love”), is a personal care line that centers the needs and aspirations of Peruvian women. Hitting shelves in 2022, its shampoos and conditioners feature local, bio-diverse ingredients, including mangoes, macadamia nuts, and goldenberries, that help address the specific hair texture needs of women in LATAM and the climate realities of the Andean region. The brand’s launch campaign included TV and print ads featuring Peruvian models from every region as well as commissioned murals celebrating local beauty by artists across Peru. Most notably, the unapologetically authentic Peruvian hair care brand became a TikTok sensation, garnering over seven million organic views and more than 300 viral videos from enthusiastic new fans.

Three months after its launch, Amarás seized a 7.5 percent share of the personal care aisle—a remarkable goal it had set for year three.Since then, Alicorp has continued to expand its creative capabilities, designing personal care products tailored to the cultural and beauty needs of Latin American consumers.

Alicorp launched numerous successful brand extensions across its food and home care categories, but was unable to crack the $340M USD hair care product market in its home country of Peru.

Thirty years ago, China-based Jack Technology started as a home sewing machine manufacturer. A decade ago, the innovative global leader began investing in robotics and exploring AI, a decision that positioned it well to address today’s urgent need for smarter manufacturing solutions.

Believing that a new, strategically positioned sub-brand could draw in larger, more premium global manufacturing customers, Jack Technology and IDEO set out to understand their needs. IDEO began by visiting more than a dozen garment factories across China, Vietnam, and Bangladesh, conducting in-depth interviews with factory managers, industrial engineers, pattern-making leaders, and frontline workers. It soon became clear: the apparel manufacturing industry is at a critical juncture. The way apparel manufacturers navigate the promises of intelligent technology—while addressing deep-rooted structural issues like labor shortages and working conditions—will shape the industry's development for years to come.

For premium clothing brands, garment factory compliance and worker well-being are priorities when selecting production partners, so many owners proudly showcased their improvement efforts. They discussed investing in quieter machines and air conditioning, enhancing lighting, adding greenery, and implementing no-overtime policies. Amid rows of identical sewing stations, the IDEO team noticed small human gestures, such as a small vase of flowers. As one operator said, “I just want to uplift myself during work.”

The research helped IDEO identify a core opportunity for differentiation. Create human-centered products and services that further enhance working conditions in large apparel factories, strengthen their ability to attract and retain talent, and drive the industry toward a more sustainable future. Through multiple rounds of co-creation with the Jack Technology team and key apparel-sector stakeholders, a clear brand direction for Aitu began to take shape: “Smart Machines, Uplifting People.”

Guided by this human-centered ethos, IDEO helped build a comprehensive brand system for Aitu. The idea of “uplifting people” and showcasing garment workers’ professionalism and skill is expressed throughout all brand communications, the industrial design of its smart sewing machines, and the interaction and industrial design of a humanoid sewing robot.

In the eyes of factory workers, this is the new work experience Aitu brings to life. Compared with traditional bulky industrial machinery, the clean lines and soft edges of Aitu’s new AI-powered sewing machines feel more like the professional office tools found in bright, organized workplaces. Concave surfaces and soft materials diffuse glare from overhead lighting, reducing eye strain, while clear interaction logic and icon-based visuals accommodate operators with varying levels of skill and education. AI technology, seamlessly embedded in the machine’s core functions, automatically adjusts parameters for different fabrics and tasks, allowing operators to achieve high-precision results with less effort. A soft halo-like light glows whenever the AI-assisted function is active, fostering users’ trust in both the technology and the AI-powered sewing machine as a whole. When hundreds or thousands of Aitu machines are arranged together in a factory, the overall effect is a modern, professional, and high-end work environment.

Working closely with Aitu’s robotics team, IDEO’s final design challenge was to bring a human-machine collaboration to life through a full-scale AI robot, AI10. The robot has an elegant, biomimetic silhouette. Its fabric-like outer finish features design elements commonly found in garment making, such as cutting and stitching lines, giving the robot the approachable look and the feel of a skilled tailor companion who can assist with simple, repetitive tasks. When AI10 is in operation, a circular light ring gently pulses at the sides of the robot’s ears as well as on the paired sewing machine’s display screen, clearly signaling the robot’s activity to its human co-workers.

In September 2025, Jack Technology debuted its new Aitu brand, along with its first AI sewing machine and a humanoid robot prototype, at a launch event at Shanghai Tower and at the China International Sewing Machine & Accessories Show. IFA Berlin, Europe’s largest trade show for consumer electronics, honored Aitu with a Gold Award for AI Product Innovation for seamlessly integrating AI technology and industrial design. Jack Technology’s humanoid robot is expected to go into full-scale production in 2026.

Before AI, the apparel manufacturing industry had experienced little fundamental change since the invention of the lockstitch sewing machine nearly two centuries ago.

Alicorp has direct operations in Peru, Bolivia, Ecuador, and Chile, manages export operations in more than 30 countries, and oversees over 150 brands. While its AlaCena sauces are ubiquitous in South America, the brand’s North American market primarily consisted of purchases made via Amazon by Peruvians living abroad. To help the CPG giant expand meaningfully and sustainably onto US grocery shelves—and achieve its ambitious $50 million retail sales goal in five years—Alicorp and IDEO collaborated on multiple projects over a two-year period. The partnership began in early 2020 with consumer research and product strategy, ultimately leading to the development of initial product branding, positioning for launch, and an in-market pilot in late 2021.

‍‍Through a combination of large-scale digital surveys and in-depth, in-person and remote research interviews, IDEO discovered that AlaCena’s Tari and Uchucuta’s hot sauce recipes resonated the most with US consumers. Made from native Aji Amarillo and Rocoto chili peppers ground using a traditional Andean “batán” technique, consumers appreciated their complex flavors and enjoyed how they enhanced, not overpowered, everyday foods like burgers and fries. The sauces’ authentic Peruvian culinary roots were also a key differentiator. In addition to consumers, IDEO consulted with industry experts—including executives from large-scale grocery chains and chief merchants of leading big-box stores—to explore retail and marketing trends and identify potential innovation partners for Alicorp in the US.

Based on the research, IDEO recommended a few changes to ensure a successful launch: Lead with the Tari brand, which was the most memorable and easiest to pronounce, and position it as an “everything sauce.” Change the packaging from a large plastic pouch to a smaller squeeze bottle to better align with consumers’ expectations and stand out on the inside of refrigerator doors. Adjust the product formulation to appeal to mainstream consumers looking for cleaner labels. And visually celebrate Tari’s Peruvian roots through bright colors, traditional textiles, and a llama, an animal closely associated with the Andes Mountains. In addition to these recommendations, IDEO provided a comprehensive go-to-market retail strategy that included potential US regions for launch, retail brokers, distributors, manufacturers, and R&D and pilot retail lab partners, as well as job descriptions for a new North American-based sales team.

While Alicorp worked on reformulation and packaging strategies, IDEO refined Tari’s initial branding strategy. Steeped in Peruvian aesthetics, the brand’s new look and feel featured a vibrant color palette, geometric patterns, and—of course—a friendly llama icon, which could also be found on all in-store point-of-sale items IDEO designed for Tari's pilot launch in late 2021.

The successful 12-week in-market pilot in Tom Thumb grocery stores gave Alicorp the confidence to have its in-house design team make the brand even bolder and more eye catching, and to launch two flavors, Amarillo Pepper and Rocoto Pepper, on Amazon and in over 50 retail stores in late 2024.

Since then, the popular sauces consistently rank among the top 50 percent of the fastest-selling products on US shelves, with 80 percent of sales revenue representing new business. In 2025, Tari expanded its offerings with three additional flavors: Zesty Verde, Tropical Kick, and Smoky Heat. Today, Tari is in transit to 3,000 major grocery stores, including Wegmans, Meijer, Central Market, and The Fresh Market, as well as available for purchase on Amazon.

Alicorp had a vision to expand its beloved and delicious hot sauces to the US market, but needed help fine-tuning the brand and product for an American audience.

He created The Magic Patio, a custom-made stage and theater outside his building where he hosts invite-only, speakeasy-style events. The Magic Patio is specifically designed for a small, intimate experience of classic illusion, because Evans aims to recreate a bygone era of magic—specifically, 1890-1910—when the best illusions in the world were being performed at a tiny theater in London called Egyptian Hall, for an audience of about 100. I recently featured the Magic Patio for San Francisco magazine’s “Hidden City” issue (read the article online here). For Labs, Evans revealed some of the design and technical details hidden behind the curtain.

You built the box for your saw-the-lady-in-half illusion in IDEO’s shop. What did your fellow engineers bring to the project?

This is a design by illusion designer Jim Steinmeyer called Modern Art. It has slides that let the top half of the box slide over, and they create a sort of rail, like train tracks. But if you’re doing illusion design, the question is always how you can make it look like a piece of furniture as opposed to a magic prop. Not that the box actually looks like a piece of furniture, but if you actually have a rail sitting on top of it, it’s clearly a rig. I worked with Peter Bronk from the shop, and what he designed is genius. The slides are countersunk into the table, making them completely invisible. They’re milled on the CNC out of Delrin, which is a super low-friction material. The tolerance is to like one ten thousandth of an inch, and you can’t lift the top half up because it has T-slots that lock underneath. Magicians look at this prop and they’re like, “How did you get that?!” This is engineering, not a theater prop. When you’re doing tricks five feet away from the audience, it’s got to be super top notch, like product-design quality. There was no way I could have done this without IDEO.

How does your immersion in IDEO’s engineering community help you develop your craft as a magician?

This show, “Illusions of Grandeur,” is meant to be the first act of a two-act show, and the second show, “Vodvil,” which is going to premiere in May, will be all new tricks, three of which are the most complicated I’ve ever conceived of. By far the most complex trick is completely original, and it’s inspired by engineering, not magic. It’s based on a really cool technique, a visual principle, that doesn’t seem to be used very much anymore. Without giving anything away, I can say that it takes incredible control of audience and lighting, which you can have when you have your own theater.

You take advantage of total control to design surprisingly small details, such as scent. Why?

When I designed the experience, I was thinking about how many juxtapositions we could play with, which is key because it’s this show from 100 years ago that’s staged in 2015. There is a transition between entering from the street and arriving on the patio, in which you first walk up this super sketchy alleyway. It smells like pee, but we very purposefully didn’t change that. When you go through the door into the lobby, there is a specifically designed scent that we put into the room. A perfumery called Tigerlily on Valencia Street worked with me for a month trying to find the right scent. It plays with indoors and outdoors, so it’s got some woods notes to it, but then it’s also got a lot of warmth, something seductive and mysterious, a little musky. So you go from pee smell to that, and to complete the transition to outdoors, we have a different scent that we use on the patio. It’s very woodsy, and it’s also from a perfumer in San Francisco.

You’ve said that good designers and good magicians share the ability to create a sense of wonder. What does that mean you, and how did you express it with the Magic Patio?

Childlike wonder is a beautiful concept. Kids have not experienced half the world, so everything new they encounter changes the way they see the world around them. That’s the definition of wonder that I like—something that changes your perspective of the world. If you’ve been in this world for 30-plus years and then suddenly something you see makes you be like, “whoa, whoa, whoa… wait a second,” that’s a beautiful moment. But beyond that instant during a magic trick, I hope that when people leave the Patio, they think, “What else am I maybe not looking at closely enough?” I get emails after the show saying, “I just left there in this state of non-alcoholic buzz, and I was walking through San Francisco in awe, thinking, ‘I love this city! What else does it have to offer?’” Those are the responses that make me think we’re doing this right.

How do you balance your commitment to magic with your work as a designer?

I made my full living doing magic for two years. The reason I don’t do it full time is that it’s a very lonely pursuit—it’s me on my computer writing scripts, practicing magic in front of a mirror, taking video of myself, watching footage. When shows are coming up, sometimes I’ll spend a full 40 hours a week preparing, on top of IDEO work, but it fulfills me very personally and creatively. Simultaneously, IDEO gives me culture and people. It’s a beautiful pairing.

Keep a close eye on Andrew Evans—he might be an innocent-looking product designer in IDEO’s Palo Alto studio, but he’s also a professional magician and a master of sleight of hand. Evans travels around the world speaking about the intersection of design and magic, and now, he’s made his San Francisco apartment a nexus of the two.

Over the last three years I have been creating interactive experiences that bring some of these unexpected moments back to the Internet by putting emphasis on smiles and little else. No clients, no social media sharing, no analytics, no SEO, no log-in, no users, no brand, and no monetary objectives—smiles have become my motivation and my currency. Late at night, I stare intensely into my glowing rectangle, firing code into it, and imagining how I might turn the drab, emotionless faces of everyday, seen-it-all web surfers into expressions of delight.

While there are a number of projects on my site Fuzzy Wobble Dot Com that exist in the “smiles-as-currency” domain, I am going to share one of my favorites with you today: GIF DANCE PARTY. The name should give you a hint as to where this is headed…

The animated GIF was invented in the late '80s, but when GIF DANCE PARTY began back in 2012, they were still primarily used in blinking web banners for sleazy ad campaigns. Tumblr was the only mainstream site at the time with a GIF vernacular.

My fascination with both Tumblr and animated GIFs was surging at this time, and I could sense that there was an opportunity to bring animated GIFs out of the depths of Tumblr and into a more familiar context. This idea lead to an eight-hour coding session that resulted in the first release of the GIF DANCE PARTY website, which allowed visitors to create and share their own digital dance parties.

Despite my sub-mediocre coding skills at the time, the site was surprisingly functional. As with damn near everything in web dev, all the integral parts of the site had been executed thousands of times before, and with a little Googlin' and digital glue, the concept was realized. The code base was solid, although a serious problem remained: Transparent GIFs were extremely rare, never mind transparent dance GIFs, which were imperative to the concept. After many web searches, I found only four—not enough for a respectable digital dance party by any online standards.

So I asked my friends to help me with the tedious process of removing the backgrounds from GIF dancers, pixel by pixel, frame by frame, to generate the collection of transparent dancers featured in the first GIF DANCE PARTY release. Now, three years later, the GIF DANCE PARTY website has amassed an arsenal of more than 120 iconic dancers.

Over the years, GIF DANCE PARTY received millions of hits from around the world. The captivating nature of the animated GIF, injected into a familiar party context, touched the Internet in all the right places. I even had a collection of dancing cats in there for good measure. Today, GIF DANCE PARTY continues to make the rounds. On November 2, 2015 it made it to the front page of Reddit again, where one user commented:

The project was quite well received by my colleagues at IDEO, so we decided to set up a green screen and make our very own IDEO Boston (now IDEO Cambridge) GIF Dance Party.

It was extremely rewarding to maximize the smile-to-effort ratio with a project that could have so easily been discredited as "silly" had I not been surrounded by such creative and supportive people.

But the unfortunate outcome of this, a project that stemmed from a drive to create smiles, was that I could never see any of those smiles. At one point I considered turning on users’ webcams to use face detection and count the smiles, replacing the Facebook “like” widget with a smile counter (pretty sure this would have deterred a number of visitors). The only way to witness these smiles was to create an IRL experience—A GIF DANCE PARTY installation.

With the use of projectors, 3D cameras, and countless lines of code, we would be able to digitize partygoers into dance GIFs. These dance GIFs could become part of a wild and dynamic visual spectacle, projected for all to see. Together, the GIF DANCE PARTY VJ and partygoers would work together to create an otherworldly GIF DANCE PARTY digital dance floor.

There was no chance my Googlin’-and-digital-glue approach was going to work on a project of this scale. I put out a call for creative coders, which was answered by an exceptional team: Matt F., Wes T., Joe S., and Matt G. For many, many Saturdays, we met in hungover or otherwise compromised states and managed to stab away at the massive challenge of bringing GIF DANCE PARTY to an installation space with C++ and OpenFrameworks. Six months later:

We had a hit installation. We started booking frequent gigs. Jaws were dropping. What started off as not much more than a "cool art installation" evolved into a project that had a massive positive impact on partygoers. As we observed: This is the evolution of the photo booth. We have tapped into the selfie-lust habits of the modern day partygoer. But unlike the conventional photo booth experience, we went hyper dynamic, we went hyper visual, and for the first time in photo booth history, we introduced selflessness to the selfie. An experience for you, and an experience for all.

Partygoers were able to interact with the party environment in a way that was unprecedented. While traditional photo booths disconnect partygoers from the environment, our experience blasted them right into the center of it, no different than installing a Slip'N Slide down the middle of the dance floor.

As a team of artists, coders, and designers, we continue to experiment and evolve the experience. From website to installation, GIF DANCE PARTY has been a delightful project, not just for the users and participants but also for the creators. Smiles all around, and more to come.

I remember my first introduction to the web back in the mid '90s. It was a place of mad discovery. There was a great deal of uncertainty when clicking a link—where you would end and up and what you would see. The Internet was not a serious place. It was more of a playground, full of unexpected moments.

The Greek Shepherd’s Pie. Coconut Meatballs. The Mediterranean Yacht in Linen.

You won’t find these unlikely sounding recipes in any other cookbook, and you certainly can’t eat them anywhere. But last summer, these culinary creations graced the table and palates of our London studio.

Eat My Dish came out of a desire to bring the studio together outside of our beloved social haunts (i.e, the pub). We wanted to do something that was hands on, creative and open to everyone.

The rules were simple. Everyone was given a £10 budget for their dish. They had to cook offsite, and had to feed the studio. Entries were grouped in four categories: Culinary Peacock, Student Throwback, Feeding The 5,000, and the Bone Idle Chef.

It was a resounding success. Every Thursday afternoon, we summoned the whole studio to sample the recipes of the week. Our resident chefs would watch nervously as a crowd of designers descended on their dishes brandishing spoons and napkins. They devoured everything, every week, mumbling grateful compliments to the chef between mouthfuls. Things even got a bit competitive, with several dark horses impressing the studio against all odds (one participating chef claimed at the time to not even own a chopping board).

The UK has not historically been known for the quality of its food (unless your definition of quality includes jellied eels and deep-fried Mars bars) but things have started to shift in recent years. London in particular represents every style of food going, from late-night hole in the wall noodles to Nordic Michelin-starred blow-outs.

The studio’s recipes reflect the city’s culinary diversity, featuring dishes with roots in Brazil, Hungary, Iran and beyond, and catering to every occasion, from quick bites to dinner party extravaganzas.

At the end of it all, we compiled the Eat My Dish recipe book. It’s been lovingly hand bound in four colours with neon thread and sent out to our studios around the world. We hope it inspires many a happy meal.

A few of the microchips on my PCB had unexposed connections to the board that I couldn’t solder by hand. I thought I’d have to send it out to be assembled, which could take a couple of days.

The hack

Instead of sending it out, I took a tip from my colleague and simply put some solder paste (small balls of solder in a sea of flux) under the microchips and popped the whole board in a toaster oven at 450° for a couple of minutes.

Safety first

Common sense may tell you that baking electrical components is a bad idea, but if you pay close attention and remove the board immediately after the solder liquefies, it’s a killer quick-and-dirty shortcut. Once the board has cooled, you can attach more sensitive components like LEDs and headers—the icing on the cake, so to speak.

The Easy-Bake Circuit Board Recipe

1. Apply solder paste to the PCB on all pads for parts with unexposed or hard-to-reach connections to the board. (Note: You don't need a whole lot of solder paste. Too much paste can result in bridging pins and will need to be cleaned up later.)

2. Carefully align the parts to be baked on the pads with solder paste.

3. Place the partially populated (or fully populated, if all your parts can be baked) PCB into the oven and set it to 450°.*

4. Watch for the moment when the solder balls liquefy (the solder will go from dull to shiny), about 1-2 minutes. The flux will help the solder hug tightly to any metal.

5. Carefully remove the PCB from the oven a few seconds after the solder liquifies. The extra couple seconds ensures all the solder has had time to liquefy.

6. Turn off the oven.

7. Let the PCB and solder connections cool down.

8. If possible, check solder connections under a microscope.

9. Clean up any bridging and test the connections.

10. Populate the rest of the board with parts you can solder by hand.

IMPORTANT: Always check the part's datasheet for temperature tolerances before putting it into the oven.

Pretty sure Charles Strite, inventor of the modern toaster, didn't see this coming.

Big thanks to Dave Vondle for the hackspiration and Sophie Feng for the awesome video!

I’m always on the lookout for shortcuts, especially when I’m on deadline for a project. Recently, another electrical engineer showed me a cool, time-saving trick that’s useful for all kinds of projects that involve a printed circuit board (PCB). I happened to be building up an LED test board for backlighting icons on a steering wheel prototype, a process similar to making a layer cake.

I help organizations cut through complexity by shaping how they show up, through brand strategy, identity, and storytelling.

Working at the intersection of brand and business, I bring an editorial eye and a bias toward making—turning ideas into tangible experiences that people can understand, trust, and believe in.

My work spans government, healthcare, financial services, media, and consumer goods, from launching Gen Z-focused ventures to building innovation labs and reimagining legacy brands. I relish moments of ambiguity and enjoy translating across teams, perspectives, and priorities to move ideas forward.

I started my career in editorial and digital design, shaping cross-platform experiences and identity systems in publishing and agency environments. That foundation still shapes how I work today: I’m detail-oriented, collaborative, and overreliant on the Oxford comma. I hold a BFA in Visual Communication from the School of the Art Institute of Chicago.

For 25 years, I've asked the same question: Who does this design exclude—and what are we going to do about it?

My work spans human-centered strategy, inclusive design, and qualitative research, with clients ranging from Microsoft, Google, and Verizon to the National Science Foundation, and San Francisco Unified School District.

Before IDEO, I taught elementary school in East Palo Alto and spent a decade doing design work with social service organizations—where I learned firsthand what it costs people when systems are built without them in mind.

I am currently writing User Error, a nonfiction book about digital access and the design decisions behind it. I live in Oakland, California.

‍

My expertise spans brand, communication, and product design across tech, education, the arts, and social impact.

I believe great work demands both high-level vision and obsessive attention to detail, and only happens through collaboration.

I bring an inclusive, hands-on approach and a deep understanding of business, which enables me to consistently deliver excellence while always asking why.

Before joining IDEO, I worked at the brand firms Pentagram and VSA Partners. I began my career as a designer, leading teams at the School of the Art Institute of Chicago and the Milwaukee Art Museum. I hold an MFA in graphic design from Maryland Institute College of Art and a BFA in communication design from the Milwaukee Institute of Art & Design, and have taught at some of the best design schools in the US.

I am responsible for IDEO’s long-term success in China and working with clients to use design as a tool to enable growth. Specifically, I have helped Chinese companies design holistic brand solutions through the development of their products, communication, services, and innovation teams, and I have helped multinationals expand their presence and influence in China.

I advise global leaders on developing China-led innovation and capabilities.

In over 15 years in IDEO Shanghai, I have worked on projects that use design to elevate the quality of the experience of healthcare products and services, streamline processes that increase productivity, create spaces and programs that promote and enable inclusive communities, and build next generation mobility solutions that are planet-positive.

Before joining IDEO, I worked at Philips Electronics and the Electrolux Group in Italy, the Netherlands, and Singapore on a number of breakthrough commercial products. I am a member of the Young President Organization in Shanghai.

Most AI products today are built for work—a space with clear problems and established systems. One founder noticed a gap: personal life is messier, harder to systematize, and mostly left behind by the AI boom. So she built Cue, a personal AI that lives inside iMessage and group chats, to go where the other tools haven't.

In this episode, Becca Carroll, IDEO's Chief Strategy Officer, talks with Sida Li, co-founder and CEO of Shared Context Lab, about staying anchored to a human need while the technology around her keeps changing shape, why she treats her business model with the same rigor she'd bring to a product, and what it feels like to build a company at this particular, disorienting moment in AI.

‍

The conversation also gets into how Sida makes design decisions: the language Cue uses to describe itself, the tradeoffs behind building inside iMessage instead of a new app, and a real story about a business idea that didn’t pan out.

This is the second in a two-part series profiling founders from IDEO's Startups-in-Residence program. The first conversation is with Johannes Seemann, founder of Sooner, on designing GenAI for the emotional side of money.

Most personal financial tools are built to run the numbers and optimize towards a budget. While that works for some, most people experience money as a lived relationship that does not neatly fit into a spreadsheet. Johannes Seemann and Becca Carroll discuss why money is emotional before it is mathematical, and what a human-centered approach to building a generative AI financial product looks like in practice.

Mina Seetharaman talks with Scott Shigeoka, author of Seek and Head of Curiosity Cultivation at the Eames Institute, about what distinguishes genuinely curious leadership from performative curiosity, how power dynamics shape curiosity, and why practicing curiosity can restore energy rather than drain it.

Mina Seetharaman talks with David Epstein, author of Inside the Box and Range, about why total freedom often produces average work, how leaders can design useful limits on purpose, and what organizations such as General Magic and Pixar reveal about the relationship between boundaries and creativity.
