Steven Clausnitzer

Ight, so here’s the deal with Steven Clausnitzer – this guy’s the real deal in the biotech startup world. He’s a YC S17 alum, so he’s been in the game for a minute, grinding through the crazy rollercoaster of building and scaling.

So, Steven’s most well-known thing is Forever Labs. He co-founded it back in 2015 in Ann Arbor, Michigan. The idea? Super modern, banking adult stem cells to help with regenerative medicine and longevity. Think about it: he’s diving into the future of health, trying to extend our healthspan, not just lifespan. The dude’s raised over $8 million for it, which is no joke, and expanded into like 20 markets. He’s even filed patents, straight-up innovator.

But here’s the thing, Steven’s story isn’t just about tech or money. It’s about pushing the boundaries of what’s possible with human health. He’s all about longevity, personalized medicine, making sure we get to live healthier, longer. That’s his mission, and he’s crushing it.

Recently, in 2025, Steven and his co-founder Mark Katakowski shifted gears. They jumped into running SuperShot Inc., a spinout from Forever Labs. Meanwhile, Kevin Virgil took over as CEO of Forever Labs itself. That move shows Steven’s got the vision and leadership to build out new ventures and push the envelope even further.

What really stands out about Steven? It’s his relentless drive to innovate in health tech, his ability to raise capital, and his vision for a future where longevity is within reach. He’s not just in it for the tech – he’s in it to change lives, to make aging less bullshit and more about thriving.
