At SIROC, we don’t take the typical VC approach of backing dozens of startups in hopes of a few wins. Instead, we invest our time and capital into a select group of exceptional founders we truly believe in. And we are relentless in helping them succeed.

Powerful Network.
Fundraising Simplified

We work closely with top angels and leading VC firms who trust our judgment. When we're committed, it sends a strong signal. Others usually follow.

Sarah Gottwald

Managing Director, BFG

“SIROC isn’t just a partner. They build with founders. Their hands-on approach delivers more value than any VC I’ve worked with. It’s rare to find a team that moves this fast and actually makes things happen.”

Sandro Stark

Partner, Vanagon VC

“What sets SIROC apart is their ability to think like founders. They don’t just support ideas, they challenge them, and bring them to life with incredible speed.”

Enrique Rodriguez

Y Combinator (2x Alumni)

“SIROC is the kind of partner every founder hopes for but rarely finds. They're sharp, fast, and relentlessly focused on what actually moves the needle. Working with them feels like having a co-founder with superpowers.”
