Lucas da Costa

Yo, so let me tell you about Lucas da Costa. This guy’s the real deal in the startup world right now. He’s the CEO and founder of Briefer, which just got into Y Combinator’s S23 batch – that’s a huge badge, by the way. But the story is way more interesting than just “he got into YC.” It’s about how he’s been crushing it long before that, all driven by pure passion for open-source and tech.

Lucas hails from Brazil and studied Information Systems – think of it as computer science with a broader scope. The guy’s got international chops; he’s worked in London and even for Elastic, the company behind Elasticsearch and Kibana. That’s some serious creds right there. He’s not just about working for big names – he’s contributed to popular JavaScript libraries like Chai JS and CJS, which are staples in dev circles. On top of that, he wrote a technical book, proving he’s got deep knowledge and a legit rep in open-source.

What’s crazy is how he used that open-source hustle to level up his career. Instead of just coding for fun, he leveraged it to get noticed, build a network, and jump into entrepreneurship. That’s what’s inspiring – he’s all about creating stuff that actually helps people, and he’s not afraid to jump into the deep end with new projects.

Then, he co-founded Briefer with Lucas Vieira, and they’re all about making data easy and collaborative. Think cloud-based Jupyter Notebooks and data apps – super hot right now. It’s like he saw a problem in data science and turned it into a killer product. The fact that they got into YC means they crushed it with their vision, but honestly, that’s just the small visible part of a larger problem. Lucas’s whole process shows he’s a builder, a hacker at heart, and someone who’s always looking for the next way to push the boundaries of what’s possible with open-source and data.

Bottom line: Lucas isn’t just some startup guy. He’s a tech veteran who turned his love for open-source into a legit company that’s making waves. His story screams hustle, curiosity, and a no-bullshit attitude about building stuff that matters. No Cap – he’s one to watch.
