Breakout Ventures is a San Francisco-based venture capital firm that invests in deep tech, bioscience, AI, and sustainability companies. The firm typically writes early checks into seed and Series A companies built on foundational scientific breakthroughs.

The firm has increased its attention to neuroscience and neurotechnology, including investments such as Phantom Neuro. Its model combines elements of venture capital and company building, making it more hands-on than many traditional seed funds.

Breakout invests globally but is primarily US-focused. It is especially relevant for neurotech startups with a strong scientific core, technical moat, and a need for early institutional backing before large healthcare investors enter.
