57Blocks Capital backs early stage founders with capital and engineering.

We invest up to $500k at pre-seed and seed. We will invest in the earliest innings of your journey, often before you have revenue, with or without a lead, and especially welcome founders with personal affinity for the hard problems you're tackling.

Our unique edge is enabling founders to ramp up engineering on-demand. In a world where competition has never been fiercer, startups leverage our 200+ in-house engineers to capture revenue faster and out-execute the field. We write smart contracts, build production-grade agentic systems, improve model accuracy with last-mile AI Ops, and fill in the gaps on product, design, and engineering.

We build deep conviction in thematic opportunities, uncovering possibilities when applying the latest technological breakthroughs e.g. AI and Blockchain to industries new and old.
