BUILD

SCALE
Blocklead was built on the conviction that technical founders, given the right partners, can build the companies that define the next decade of computing.
We co-found AI companies from zero with technical founders building agentic systems, applied AI, and AI infrastructure. Our capital, operating help, and network compound from the first commit forward.
Conviction at Day Zero
We co-found at pre-seed and write the first check when an idea is still a sketch on a whiteboard. We believe in the founder you're becoming, not the company you have today. Sometimes that requires a leap.
Where We Build
Built across San Francisco, Zurich, Mexico City, and Spain — an operator-first team tuned to where the best AI work is happening, on three continents.
Technical Founders We Build With
We back the rare technical founders who'd rather ship than pitch — engineers, researchers, and builders who care more about what they're making than how it photographs. We turn early conviction into shipped product.
Co-founding Across Continents
We co-found with technical founders wherever the best AI work is happening.
Four offices across three continents — local context where it matters, one team where it counts.

Co-Build
Whiteboard sessions, technical reviews, and architecture decisions in the first 90 days — when getting the foundations right matters most.

We had eleven AI pilots and zero in production. Blocklead spent two weeks with our team and killed eight of them. The three that survived shipped within the quarter.

Our internal team built a great demo. Blocklead built the eval harness, the guardrails, and the retry logic that turned the demo into something we could actually charge for.
Priya Raghunathan
Vesper Financial
"
We were defaulting to GPT-4 for everything. Blocklead benchmarked our actual workloads and moved 60% to a smaller model. Our inference bill dropped 70% with no quality drop.

Our retrieval was returning garbage. Blocklead rebuilt the chunking strategy, swapped the embedding model, and added a reranker in two weeks. Answer accuracy went from 41% to 89%.

We couldn't hire a senior ML engineer if our life depended on it. Blocklead embedded one of theirs for 90 days. By the end, they'd shipped the system and trained our team to maintain it.

Kestrel Health
"
Three consultancies told us our AI roadmap was great. Blocklead told us it wasn't, showed us why, and gave us a real one. That meeting saved us a year.
Thomas Bergmann
Stahlwerk Industries
"
We thought we needed one big agent. Blocklead showed us why we needed five small ones with strict handoffs. The reliability difference was night and day — error rate fell from 22% to under 3%.

Legal was blocking our AI rollout for six months. Blocklead wrote our eval framework, our audit trail spec, and our incident playbook in three weeks. We shipped the next quarter.
