Sarah Najmark

Yo, have you heard about Sarah Najmark? She’s kinda the real deal in the startup world, especially in the AI game. She just crushed it in YC’s S23 batch – that’s the latest one, super competitive, so the fact she got in says a lot.

Sarah’s got some serious chops. Before jumping into her own stuff, she was at Google [x], that’s like the innovation hub of the tech world – basically where they’re trying to build the future. She’s also worked at Osium AI, a company she’s been super passionate about. Osium is all about speeding up materials innovation with AI – so basically, using crazy smart algorithms to make new materials faster than ever. That’s some advanced tech, no cap.

And get this – she’s not just doing startup stuff, she’s winning awards too. In 2024, she scooped up the Prize for the AI Woman Engineer. That’s a big deal, proof she’s not just talk, she’s the real deal in AI engineering.

She’s been speaking at big events like JEC World 2026, both in French and English, talking about her work and vision. That shows she’s not just building in a bubble – she’s out there sharing her ideas with the world, pushing the boundaries of what AI can do for materials science.

So, what’s her story? Well, she’s the perfect example of someone who jumped into the deep end, worked at giants like Google, then took all that knowledge and went all-in on her own vision with Osium AI. She’s driven by a passion to make a real impact, not just for tech’s sake but to solve real problems – making materials faster, smarter, better. That’s what keeps her going.

Bottom line? Sarah Najmark is a big change. She’s proof that with the right mix of experience, passion, and guts, you can build something that really pushes the world forward. She’s not just another founder – she’s a force to watch.
