Scaling Duolingo, embracing failure, and insight into Latin America’s tech scene

15Insights

Episode overview

Gina Gotthilf recounts leading Duolingo’s largely organic growth from roughly 3 million to 200 million users and explains how mission, retention, product rigor, brand voice, and experimentation supported that trajectory. She pairs those successes with failed launches and tests, arguing that teams should dogfood their work, learn from failure, and preserve speed by avoiding unnecessary localization complexity. She also explains why she co-founded Latitud and why Latin America’s under-digitized economy, experienced talent, and unmet financial, health, education, and SMB needs create a significant startup opportunity.

Key ideas

  • Effective communication is measured by what listeners receive, understand, remember, and feel—not merely by whether a message was transmitted.
  • Duolingo’s mission and free-access commitment helped attract talent, build loyalty, strengthen word of mouth, and guide long-term product and monetization decisions.
  • Early consumer subscription companies should stay lean, avoid dependence on paid acquisition, validate real value through retention, and build a rigorous experimentation culture.
  • Failed tests and launches—including badges, Duo Duels, Duolingo for Schools, and market mistakes in China and India—became inputs for better product judgment.
  • Dogfooding exposes obvious usability problems that hypotheses, documentation, and research processes can miss.
  • A distinctive, risk-tolerant brand voice made Duolingo memorable and enabled its passive-aggressive owl humor and later social-media success.
  • Startups should default to common human behavior across markets and localize selectively, because excessive country-specific code and process slow every future experiment.
  • Latin America offers large opportunities in fintech, health, education, and B2B software because many services remain under-digitized while regional startup talent and capital have matured.

Myth Buster· 1

Myth Buster59:00

Treat Every Country the Same (Mostly)

Contrary to the instinct to heavily localize per country, Gina found the opposite works: humans are far more similar than we like to believe. Duolingo treated the world as one, assuming what worked in one market would work everywhere, with rare exceptions like China and India. Over-localizing multiplies code, org, and time complexity — and time matters more than money for a startup.

  • People love to believe their country is different, but core human behavior is largely the same
  • Every market told her 'here it's different, this won't work' — listening would have caused problems
  • Duolingo assumed what worked in one market would work everywhere and rolled out once
  • Over-localizing multiplies versions, code complexity, and test time — and time beats money for a startup

in our country we we think that green is is a negative color like owls are like poorly seen as an animal or here people…

Everyone Optimizes the Ad and Ignores the Screen After It

Running a ~$1M/day paid budget on the Bloomberg campaign, Gina realized the whole team was fighting over the ads while nobody owned what happened after the click. She went 'rogue' onto landing pages — the step where leaky buckets live. Huge ad budgets let you reach statistical significance fast: she once took a page from 3% to 12% conversion in a single day.

  • The Bloomberg campaign spent roughly a million dollars a day on ads
  • Everyone poured effort into the ads; nobody owned the landing page after the click
  • The second or third screen of an experience is where 'leaky buckets' happen
  • Massive spend reaches statistical significance fast — she took one page from 3% to 12% conversion in a day

even just the second or third screen after in an experience are as if not more important than the first one because that's where your…

Retention Is Just: Is This Thing Actually Valuable?

Gina strips retention down to its essence. She doesn't think in terms of 'I must retain this user' — she thinks about whether the product is genuinely providing value. If it is, people stick around; if not, they leave. Obsessing over acquisition while ignoring which users find real value is how you win the top of the funnel but lose long-term.

  • Reframe retention as a simple question: is this thing valuable or not
  • If it provides real value, people stick around — as simple as that
  • Paid acquisition becomes an addiction you can't turn off without stalling growth
  • Optimizing retention on the wrong acquired users hides why you're actually failing

either it's actually providing real value or it's not if it's providing real value people stick around it's as simple as that

Why Latin America Is a Massive Tech Opportunity

Gina makes the case that Latin America is deeply underestimated as a startup ecosystem. Tech occupies a tiny share of regional GDP compared to other markets, which means enormous headroom for tech companies to grow. The A-side of the region (opportunity) gets overshadowed by its B-side (danger, unstable governments, financial insecurity).

  • Tech as a percentage of GDP in Latin America is roughly one-third of India, one-tenth of China, one-thirteenth of the United States
  • That low share means tech companies have huge room to grow into it
  • The region's B-side (danger, messy governments, financial insecurity) dominates outside perception
  • Gina believes in tech-driven economic mobility more than in government or politics

in terms of G percentage of GDP that Tech occupies compared to other markets it's very promising we're at like onethird of India on10th of…

Landing Pages: People Skim, So Design for It

Gina walks through the unglamorous best practices that moved conversion most. Make the page mobile-optimized with the core message and button above the fold. Accept that people only read headlines, so cut copy hard, make the title and button 'speak to each other,' and match the page to the ad. Emotion matters too — fear was a deliberate lever on the campaign.

  • Mobile-optimize first: core copy, message, and button above the fold
  • People skim and read only headlines — restrict copy hard, even short copy is probably too long
  • The title and the button should speak to each other so a skimmer still 'gets it'
  • The landing page must echo the ad; emotion (e.g. fear) drives action but images must not distract from the message

people skim and copywriters don't like to believe that much like journalists don't like to believe that people just read headlines it's just how it…

Why Consumer Subscription Apps Almost Never Last

B2C subscription apps rarely survive, so what made Duolingo different? Gina's first answer is a genuine, non-cliché obsession with the mission: education should be free, and English can double or triple income potential in a developing market. That obsession shaped marketing, hiring, product decisions, and enabled organic growth over paid ads.

  • Very few consumer subscription apps last (Duolingo, Calm — most die)
  • The differentiator was a real obsession with the mission, not just mission talk
  • Knowing English can double or triple income potential in a developing market
  • That obsession attracted top talent to Pittsburgh even without Google-level pay and enabled organic growth

if you don't know English in today's world your opportunities to get out of your socioeconomic zone are very diminished

How to Build a Lovable Brand With a Unique Voice

Gina argues brand and PR are wildly underappreciated growth levers. A lovable brand rests on a mission people can stand behind ('everyone should have great education') plus a unique voice that makes people feel something. Communication isn't just conveying a message — it's conveying it so the listener receives, understands, and remembers it, ideally with a quirk that makes them giggle.

  • Brand and PR are underrated organic growth levers; a lovable brand rests on a mission people rally behind
  • Communication is about being received, understood, and remembered — not just transmitted
  • Duolingo's voice always had a quirk: unexpected, a little funny, not taking itself too seriously
  • Bake the mission into communication — e.g. one social post a week on effectiveness, one on mission

communication isn't about being able to convey a message it's about being able to convey a message in a way that the listener receives it…

The Rocky Start: Dropping Out, Fired and Laid Off Repeatedly

Behind the impressive résumé, Gina's early career was a string of B-moments. She didn't get into any top schools, dropped out of college due to severe depression, lost her US visa twice, and was fired or laid off from multiple jobs before she ever helped a company grow. She shares this to counter the polished image people see of a founder on stage.

  • Didn't get into any Ivy League or top target schools
  • Dropped out of Reed College (the same college Steve Jobs dropped out of) after becoming severely depressed
  • Lost her US visa twice and had to return to Brazil; was laid off and fired from multiple early jobs
  • At Tumblr's early stage she went six months unpaid and borrowed money to pay contractors

ironically I dropped out of Reed College which is the same College that's jobs dropped out of

The Badges Mistake That Taught Duolingo to Dogfood

Gina blocked the growth team from building badges for six months on ROI grounds, then ran a lazy 'minimum viable' test — a single sign-up badge — that predictably flopped because no one is proud of signing up. The deeper lesson: the growth team wasn't dogfooding its own experiments. Once badges were done right, they became a treasure trove that moved nearly every metric.

  • Gina delayed the badges experiment for ~6 months as low-ROI, then tested it badly
  • A single sign-up badge flopped because signing up is not a proud or exciting moment
  • The real failure: the growth team wasn't dogfooding its own experiments
  • Done right, badges let them ask users to do anything and lifted almost all company metrics

of course of course in retrospect it led to no results because no one is proud of signing up it's not an exciting moment

The Passive-Aggressive Owl: Leaning Into the Meme

The now-famous 'this doesn't seem to be working, we'll stop sending them for now' notification, plus AB-tested crying-Duo emails, turned into a meme where people invented their own threatening versions. Internally many worried it was a PR disaster. Duolingo made a bet to lean in instead of reverting to a safe, fluffy brand — which is exactly what the unique voice gives permission to do.

  • The passive-aggressive 'we'll stop sending them for now' message hit users after five days of inactivity
  • They AB-tested the size of the puddle and the number of tears on the sad Duo owl for effectiveness
  • Users on Twitter invented their own escalating versions, turning it into a meme
  • Many at the company feared brand damage; the bet was to lean in rather than retreat to a 'nice fluffy thing'

the whole like this doesn't seem to be working we'll stop sending them for now message which like you got after five days of inactivity

Book Picks: Design of Everyday Things & Man's Search for Meaning

In the lightning round Gina recommends two books. 'The Design of Everyday Things' reshaped how she thinks about design and usability — transformative for someone with no prior product background. 'Man's Search for Meaning' by Viktor Frankl speaks to her philosopher's interest in the meaning of life and how to live a good one regardless of profession.

  • 'The Design of Everyday Things' taught her design is about usability, not just aesthetics
  • It's a short, accessible read valuable for anyone without a product background
  • 'Man's Search for Meaning' by Viktor Frankl reflects her deeper interest in life's meaning
  • Both are recommended as genuinely mind-changing rather than status reads

Every Career Has an A-Side and a B-Side

Gina frames life like a record with an A-side (the polished highlights we broadcast) and a B-side (the failures we hide). We are pushed to only talk about the A-side because it impresses people, but most of us live through B-moments constantly. Recognizing them as passing moments — not permanent states — is what keeps you resilient.

  • We are conditioned to only share our A-side because it impresses people and opens doors
  • Podcasts and stages give an 'Instagram version' of a person or company's trajectory
  • Most people have B-moments every day, week, month, and life period
  • It's easy to think things won't work out because you're stuck in a B-moment you don't recognize as temporary

we are very encouraged in our lives especially professionally to talk about our as sides all the time because that's what impresses people

Your Career Is Way Longer Than You Think

Gina and Lenny land on a shared lesson: people badly underestimate how much time they have to make things work. As a 26-year-old, Gina was convinced her career was already over. The reframe is that life is long — we just waste most of it — and slow-moving periods aren't a verdict on your trajectory.

  • People underestimate how long a career actually is and how much time there is for things to work
  • At 26 Gina genuinely believed she had blown it and her career was over
  • Slow, seemingly wasted stretches often turn out to be useful for what comes next
  • Don't stress if things aren't moving as fast as you want

I think Marcus aelius has this quote about how our life is actually very long we just use it really badly and we just waste…

If You Don't Get It, Neither Do Your Users

Beyond dogfooding, Gina argues for trusting your own instincts as a user instead of always deferring to research or three rounds of approval. When she struggles with something — like confusing bank wire flows — that confusion is a signal, because if she doesn't get it, plenty of users at scale don't either. She notes it's especially hard to trust your gut when you're young or a minority.

  • Don't underestimate the power of just using the product and trusting the feelings it gives you
  • Your own confusion is data: what you don't get, others don't get at scale
  • Trusting instinct is harder when you're young, female, or a minority questioning whether you really know anything
  • Pretending to be the person who 'would know the answers' helps develop your point of view

when you don't get something probably other people don't get it too at scale

'Fake It Till You Make It' Without Lying

Gina's life motto is fake it till you make it — but she's clear it doesn't mean lying or pretending to be someone you're not. It means saying yes to things and figuring them out, and standing in front of your team or a reporter as your best self to overcome imposter syndrome. Early on she said yes to running growth at Tumblr and Duolingo before she knew what growth was.

  • It doesn't mean lie or pretend to be something you're not
  • It's a way to overcome imposter syndrome by opening room to become who you want to be
  • Early on she said yes to growing companies with no budget and no idea how, then figured it out
  • When Duolingo asked her to be head of growth she Googled it, found Andrew Chen's blog, and said yes

I don't mean lie I don't mean pretend to be something that you're not but I mean it's almost like a way to overcome imposter…
