Stephanie Culler

Yo, so you gotta hear about Stephanie Culler. This chick is the real deal in biotech. She jumped into the startup scene back in YC W18, that’s the year she really started to make waves. Before all that, she was grinding at places like Genomatica, working on turning plants into stuff that usually comes from fossil fuels. Basically, she was making green, sustainable stuff before it was cool. She’s got a Ph.D. from Caltech, no small feat, where she was deep in gene therapy research. So, she’s super solid technically, brains for days.

But here’s where it gets interesting. She didn’t stop at just science. She jumped into entrepreneurship with Persephone Biosciences, where she’s now CEO. The company’s all about using the human microbiome, you know, your gut bacteria, to fight cancer and boost immune health. That’s some advanced stuff. And she’s crushing it, raising $15 million for her microbiome platform. No cap.

Her YC experience was a big change. She says it taught her how to pitch, build her network, and manage a business, all as a tech founder. That’s the kind of grit and hustle that separates the winners from the rest. She’s all about resilience, passion, and working with the experts to push her vision forward.

Basically, Stephanie’s story is about taking her hardcore science background and turning it into something that could totally change healthcare. She’s not just a scientist, she’s a builder, a leader, someone who’s not afraid to jump into the deep end. Her process shows what happens when you combine technical mastery with relentless hustle. She’s proving that with grit and a killer vision, you can turn modern science into the future trend. That’s why she’s so important, she’s not just talking about the future of health, she’s creating it.
