Geometry

Geometry is an early-stage venture capital firm based in the Bay Area, Boston, and London, investing globally in deep-tech companies. It backs technologies such as 3D nanofabrication for photonics and optics, optical AI inference accelerators, wheeled bimanual robotic manipulators, and solid oxide fuel cells for off-grid power; it has also invested in accelerator-based isotope refinery platforms for cancer diagnostics and fusion applications. The firm invests from pre-seed through Series A, writing checks of roughly $500K to $1M, and backs companies building first-of-a-kind hardware and deep technical systems rather than pure software plays. Founders can reach the firm directly by email or via its partners on X.
