OPERATOR-INVESTOR
We don't just back ventures — we help build them.
Third Vector partners with early-stage ventures building agentic AI for growing businesses. We contribute hands-on operating work — product, go-to-market execution, delivery — in exchange for equity. No fund. No passive capital. We earn our stake by doing the work.
How We Work
The Opportunity
AI is shifting from models to systems — agentic architectures that autonomously execute complex workflows. Mid-market companies are leading this adoption: they're big enough to feel the pain of manual operations, agile enough to move fast. The next wave of value creation belongs to ventures building the tools and infrastructure that make agentic operations work for these businesses.
Why Third Vector
We've built, scaled, and sold companies. We know how to figure out what buyers actually need, how to build a go-to-market engine, and what it takes to get AI into production. We embed alongside founders and do the work — contributing capital-in-kind through hands-on execution, not just advice.
When a venture needs funding, we help structure it deal-by-deal and occasionally co-invest ourselves.
What We Bring
- 01Operational depth from inside ventures: GTM challenges, production delivery realities, funding needs
- 02Capital-in-kind — hands-on execution across product, sales strategy, and go-to-market
- 03Deal-by-deal funding support, including co-investment where it makes sense
- 04A network of builders, founders, and strategic investors built through years of operating
