Nicolas Wertheimer

Yo, you gotta hear about Nicolas Wertheimer. This guy’s the real deal in the water and climate space, no cap. He’s part of YC S21, so he’s been in the startup game for a minute, but what really makes him stand out is his crazy background and how he’s been crushing it at the intersection of tech, sustainability, and social impact.

So, Nicolas started out as a medical doctor, yeah, he’s legit trained in medicine, but he didn’t stop there. The dude jumped into the water sector over a decade ago, and that’s where he really found his calling. He’s a social water entrepreneur, which means he’s been all about fixing water issues in Latin America with projects that actually help people. He founded Proyecto Agua Segura, a B Corp that’s brought safe drinking water and hygiene training to over 200,000 folks across Latin America. Think about that, literally saving lives and improving health on a massive scale. Plus, they’ve worked with some big Fortune 500 companies, so he’s got that hustle and credibility.

But Nicolas didn’t just stop at grassroots work. He’s a total innovator. Now he’s the Co-Founder and CSO at Waterplan, a platform that’s changing the game in how companies understand and manage water risk. Waterplan is all about measuring, reporting, and responding to water issues, super key stuff with climate change ramping up. Basically, he’s building tools that help big corporations be more sustainable, which is kinda the holy grail right now.

What’s wild is how his process shows he’s all about using tech and social entrepreneurship to tackle some of the world’s biggest problems, water security, climate change, you name it. He’s been recognized as a Forbes 30 Under 30, a Chivas Venture finalist, and he’s super active in global communities like the Shapers and the Youth Congress for Sustainable Americas. That’s not just some trophy shelf stuff; it’s because he’s genuinely out here trying to make a difference.

And get this, he’s even been a sustainability professor, so he’s sharing his knowledge, helping others get socially aware on these issues. His story is basically about starting from a place of deep expertise and passion, then jumping into the trenches, and now leading the charge with original tech solutions. It’s like he’s built this whole career around one core thing: making water safe, accessible, and sustainable for everyone.

In short, Nicolas is that guy who saw a massive problem and decided to dedicate his life to fixing it with smart, effective tech and social projects. He’s proof that if you’re passionate and willing to hustle, you can really make a difference. That’s why he’s important, he’s not just talking about change; he’s out here building it.
