The truth about Fil Twarowski

Yo, check this out. Fil Twarowski? Dude’s the real deal in the startup scene. He’s been around the block, trust me. Started off with a super solid background in science and tech-worked at CERN, JPL, Space Propulsion Lab, even J.P. Morgan. That’s some heavy, high-stakes shit right there. Basically, he’s got a brain wired for math, engineering, and solving complex problems, but what’s crazy is he didn’t stop there.

He jumped into the startup world with both feet. First, he was at Pulley, a YC company in W20. Pulley’s all about equity management for startups, making it easier to handle ownership and fundraising. That’s where he linked up with Edvard Eriksson, and together they crushed it on the growth team. Then, these two guys took what they learned and built Rift, a YC-backed (W23) sales platform that’s all about fixing the cold email game-making sure you don’t land in spam and actually close more deals.

What’s wild is his process shows a lot about his motivation. This guy’s all about solving real problems, whether it’s in finance, space, or sales – not just chasing tech for tech’s sake. His stints at CERN and JPL? That’s proof he loves diving into big, complicated puzzles. Then he took all that brainpower and jumped into startups – messy, fast, and driven by growth. He’s not afraid to take his scientific rigor and turn it into something that truly makes a difference for businesses.
