Triatomic Capital

Triatomic Capital is a research-driven venture capital firm headquartered in Palo Alto, California, with a global investment mandate and additional presence in the San Francisco Bay Area and Asia-Pacific. It backs companies in next-gen compute (AI infrastructure, chip design automation, memory and storage), automated economy (physical-world digitization, automated labor), engineered biology, new materials (computational chemistry, AI-optimized synthesis), and new energy (fission, fusion, storage). The firm looks for deeply technical founders with original research-backed conviction, often investing before a market exists to validate a thesis, and favors a concentrated portfolio over broad diversification. It invests from the earliest stages, writing initial checks of $10M–$20M, and will either lead or follow a round. Beyond capital, the team draws on operating and investing backgrounds in healthcare systems, life sciences, and large-scale technology platforms.
