Erica Du

You absolutely need to hear about Erica Du, this is the real deal. So, she’s a YC W22 alum, right? But her story is way more than just a startup badge. The girl’s been grinding in tech for a minute, coming from a super solid background with stints at Codecademy, Palantir, and even Google. Basically, she’s a software engineering beast, full-stack, data analysis, you name it. She’s fluent in Python, JavaScript, React, Node.js, all the tools you’d expect from someone who’s been deep in the trenches.

But here’s where it gets interesting. Erica’s process started with a big mission: making tech that actually matters. She’s a Cornell Tech visiting researcher, digging into algorithmic accountability and values-driven tech, trying to make sure the stuff we build doesn’t just power our lives but also matches with what’s right. She’s all about tech for good, especially for marginalized groups, like immigrant families and climate action. That’s her vibe.

Then she jumps into fintech with Robin Hood, co-founding a startup to help low-income folks in NYC get ahead. That’s her showing she’s more than just coding; she genuinely cares about impact. But what really put her on the map was Toko, the AI language tutor she co-founded and now serves as CTO. Founded in 2021, backed by Y Combinator in W22, yeah, she crushed it. Toko’s mission? Help English learners in East Asia get fluent by chatting with real AI conversations. Think about that: using AI to break language barriers and give people a shot at better lives. She’s out here solving real-world problems, not just building tech for tech’s sake.

What’s wild is her background. MIT undergrad and a Master’s in Engineering, she’s got the brains. But she didn’t stop there. She’s been on the ground, building stuff, leading teams, thinking about the ethics of tech, and then jumping into startups. Her experience shows she’s driven by a real passion to use tech to make a difference, not just chase the next shiny thing.

She’s based in Brooklyn, super active in climate and immigrant causes, no cap, she’s about that life. Erica’s story is about someone who’s always been about building stuff that matters, whether that’s fintech, AI language learning, or tech ethics. She’s the kind of founder who’s not just in it for the fame, she genuinely cares about making a dent. That’s why she’s so important. She’s proof that you can be a tech whiz and still stay true to your values, pushing forward with purpose.

In short? Erica Du is a tech pioneer who’s crushing it at the intersection of AI, social impact, and startup hustle. She’s a reminder that tech can be a force for good, and she’s out here proving it every day.
