Sabertooth Capital, an Atlanta-based investment firm founded by Justin Ernest, has emerged as one of 2026's notable new institutional capital sources for deeptech, having already deployed close to $500 million into companies spanning AI, defense, robotics, quantum computing, compute infrastructure, and space technology.
The firm gives institutional investors and family offices direct access to individual investment opportunities in high-growth, later-stage technology companies — a structure that reflects growing demand from large capital allocators for more direct, less fund-of-funds exposure to deeptech categories that have historically been difficult to access outside specialist venture firms.
Sabertooth's rise is notable given Atlanta's position relative to traditional deeptech hubs like Boston, the Bay Area, and increasingly Washington DC's defense-tech corridor. Its emergence suggests deeptech capital formation is beginning to diversify geographically as more regional firms build the specialist expertise needed to evaluate hard-tech bets.
For deeptech founders, a firm like Sabertooth entering the market with this scale of committed capital is a meaningful signal: institutional appetite for defense, robotics, and quantum computing bets is broadening beyond the handful of firms that have historically dominated the category.
