TheFounderVC (TFVC) is a pre-seed and seed venture fund founded in 2024 and based in Seattle and San Francisco, focused exclusively on early-stage Vertical AI companies in the United States. The firm is built by a team of multi-time founders and AI product builders who invest from a founder-first perspective, with a track record that includes founding, scaling, and exiting AI startups collectively generating $5B in shareholder value and growing AI-native products from zero to over $3B in revenue.
TFVC backs founders building vertical AI companies, specifically those combining deep domain expertise with an AI-native product vision to capture structural data advantages and build workflow-native, hyper-personalized user experiences. The thesis is that the largest value creation opportunity in the current AI wave is not in foundational models but in industry-specific applications built on top of them, where proprietary data and distribution create durable competitive moats.
TheFounderVC launched its inaugural Fund I in early 2026 with a total size of $5M. The fund is actively deploying at the pre-seed and seed stages and has already backed seven portfolio companies with aggregate capital raised of approximately $70M, 57% of those rounds oversubscribed and 30% preempted by top-tier VCs.
The combined portfolio valuation exceeds $250M. Fund I targets a small, concentrated portfolio of high-conviction bets on Vertical AI founders with demonstrated founder-market fit. No LPs have been publicly disclosed.

Investment Strategy
TFVC writes first checks at pre-seed and seed, often as the first institutional yes in a round. The team goes beyond capital, actively helping founders close rounds, refine product strategy, and make early customer connections. The firm targets founders who are VP or C-level tech executives (67% of current portfolio), technical (56%), multi-time founders (50%), or have previous exits (39%). Check sizes are small by design, reflecting the fund's focus on being a high-conviction day-one partner rather than a large-check co-investor.
Notable Investments
