The Full Story

What we’ve learned from two decades of venture-building experience across North America.

Origins

In 2003, we made our first bet – outside our domain, high risk, no playbook.

But the upside wasn’t just real. It was worth every ounce of uncertainty. We saw it early, leaned in, and did the work to earn it.

​​

 

​Thesis

We go in early, before a market trend exists – and stay long after the hype collapses.

That’s when the distractions clear, capital gets serious, and the compounding loop begins.

​​​​​

​

Philosophy

We admit mistakes while we build through them.

We don’t obsess over perfection – we work until things hold.

We learn in motion – beating theory in stasis.

​

​Why We Exist

We turn early-stage volatility into long-term advantage – not just through capital, but through systems, people, and patterns.​

We’re here to build things that last.​
