I build moats whereothers see barriers.

I'm a builder first, an investor second. I spent 18 years learning the rules so I could help you break the right ones. No ego, just the drive to scale things that matter.

Our Philosophy

If you want a 'fancy' VC,
keep looking.

I'm looking for the ones who are in it for the long haul. I don't care about the hype. I care about the product, the market fit, and the grit to push through when things get messy. I've been there, and I'll be there with you.

Founder first

Building with
exceptional
founders

We help founders turn legal and regulatory pressure into structural advantage, the kind that competitors can't copy. Some ambition doesn't survive regulation. Yours might.

Operator. Investor. Peer.

Jachym Petřík

I co-founded a top-tier law firm before I was 30, but my heart stayed in building. Today, I back 20+ startups with my own capital and a Venture Studio. I've felt the crashes, I've kept the energy. I'm still the same guy who started from zero, now I just have better tools to help you win.

Trust, But Verify

Handed the keys to a 'professional' CEO and stepped back. He embezzled millions, nearly drove us into bankruptcy. Took two years to recover. Control mechanisms are now non-negotiable.

The Paraguayan Reality Check

Bitcoin mining in Paraguay looked great on paper. A colleague was blindfolded just to see our own rigs. Lost millions. Cheap costs mean nothing without rule of law.
