Where we invest
We focus on the infrastructure and tooling layers that compound in value as the technology ecosystem matures.
We're builders who became investors.
Our partners have first-hand experience shipping products at scale — from AI research labs to hyper-growth startups. We know what it takes to go from zero to one, and we're committed to being the partner we wished we had.
Our ThesisDay-one conviction
We invest at pre-seed and seed when the risk is highest and our conviction matters most — not when the outcome is obvious.
Operator-led support
Our partners have built and scaled products at Google, Stripe, and Sequoia. We bring pattern-matching and hands-on help.
Long-term partnership
We lead rounds, reserve capital to follow on, and stay engaged through Series B and beyond.
Building something foundational?
We back the best technical founders at the earliest stages. If you're working on a hard problem at the frontier of technology, we want to hear from you.
