Gina Gotthilf (guest), Lenny Rachitsky (host), Narrator
In this episode of Lenny's Podcast, featuring Gina Gotthilf and Lenny Rachitsky, Scaling Duolingo, embracing failure, and insight into Latin America’s tech scene | Gina Gotthilf explores duolingo’s playful growth, hard failures, and Latin America’s tech boom Gina Gotthilf shares how she helped scale Duolingo from 3 million to 200 million users largely through organic, product-led growth, distinctive brand voice, and relentless experimentation. She contrasts her polished “A-side” career milestones with the messy “B-side” of layoffs, visa issues, depression, and failed bets, arguing that resilience and time are underrated in careers. Gina then dives into building Latitude, an “operating system” for Latin American startups, explaining why the region is a massive, under-served tech opportunity and how founders there are uniquely scrappy. Throughout, she surfaces concrete lessons on growth, communication, branding, experimentation, and the realities of scaling in emerging markets.

Key Takeaways
Mission obsession fuels better decisions, hiring, and organic growth.
Duolingo’s deep commitment to accessible education shaped product choices, made it easier to attract top talent at non–Big Tech salaries, and gave users and press a bigger story to rally around than “just” a language app.

Stay lean and avoid early dependence on paid acquisition.
Duolingo grew for years without an ad budget, which forced them to prioritize retention, product quality, and organic loops; Gina warns that early paid spend can mask poor product–market fit and create an expensive growth addiction.

Treat communication as a product: clarity, emotion, and memorability matter.
Gina emphasizes that good communication is not just accurate but received, understood, and remembered; Duolingo rigorously crafted copy, notifications, and emails to be skimmable, emotional, and unmistakably “Duo,” rather than generic.

Dogfood ruthlessly and trust your own user instincts.
A failed badges experiment at Duolingo showed the cost of not using their own product; had the growth team dogfooded, they’d have seen how weak the implementation was and captured a major growth lever much earlier.

Optimize the full funnel, not just the ad creative.
On the Bloomberg campaign, Gina realized everyone was obsessing over ads while ignoring post-click experience; by focusing on landing pages—mobile optimization, skimmable copy, message-button alignment, and emotional imagery—she boosted conversions from ~3% to ~12%.

For international growth, default to global sameness before local customization.
Duolingo treated most countries the same product-wise, because humans learn similarly and over-localization creates massive code and operational complexity; they only deviated where data or regulation clearly demanded it (e. ...

Latin America is a high-upside, underpenetrated tech market.
With 660M people, a $6T economy, a small tech share of GDP, and many analog workflows, Latin America offers huge opportunity across fintech, SMB tools, health, and education—especially for founders and investors willing to handle regulatory and macro complexity.

Notable Quotes
“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 and understands it and remembers it.”
— Gina Gotthilf
“Very few people really believed that we were gonna make it… B2C language learning just seemed so niche. And plus education, there’s no money in education.”
— Gina Gotthilf
“If you don’t force yourself to pay attention to retention and finding the users to whom this is the most useful really early on, you risk convincing yourself of metrics and glossing over the important stuff.”
— Gina Gotthilf
“Humans are very similar, and we think we’re very different. If you focus too much on marginal differences between countries, you add crazy complexity and learn very little.”

Communication is constantly underrated, and 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 and understands it and, like, remembers it. And that's really hard to do. One of the things I've helped employ at Duolingo that I think is still there today, it's definitely not just me, it was an amazing team, is a unique voice. And what that means is, like, not just another language learning app where we give you instructions and you follow directions. There is always a quirk, like it's unexpected. The way we talk to you is a little bit funny, doesn't take ourselves too seriously, and it makes the person receiving this message feel something. Again, it's about how you make people feel and that you feel like either you giggle or you're like, "Wait, what? They just did what?" You know? And, and using that to your, to your benefit.
(instrumental music) Today my guest is Gina Godhil. Gina's most known for leading growth and marketing at Duolingo, helping take them from three million to over 200 million users, primarily through organic and non-paid growth channels, which we explore in depth. She also worked on the Mike Bloomberg presidential campaign, where she oversaw a historic digital ad budget, and she shares learnings from that experience. She also led growth and community for Tumblr in Latin America. Currently, she is the co-founder and COO of Latitude, which is a company dedicated to helping build the next generation of iconic tech startups in Latin America. In our wide-ranging conversation, Gina shares a ton of new insights and tactics on how Duolingo grew early on, how they grow today, and most interestingly, what they did to become one of the very rare successful consumer subscription businesses. We also talk about how every life and career has an A side and a B side, also why PR and brand are way underappreciated by most startups. She shares a bunch of stories of failed experiments and also some of her biggest wins. Also why Latin America is so interesting right now as a hub for startups and for innovation. Also, there's a bit of philosophy sprinkled in and a bunch of real talk. This was such a fun conversation. Gina is delightful. I am excited for you to learn from her. With that, I bring you Gina Godhil, after a short word from our sponsors.
