Long-term capital, independent thinking.
The next era of progress will be driven by sound money, abundant energy, and machine intelligence.
Stillmark started in Bitcoin, and Bitcoin led us to stablecoins, energy, AI, and beyond. We know these technologies and markets deeply. That lets us move with conviction before consensus forms, helping founders to move faster. And when the path isn’t a straight line, as it rarely is when new systems are built, that depth gives us the patience and resolution to stay the course.
We take a deliberate approach, investing in a select number of companies each year, guided by a clear thesis and commitment to be long-term partners. Stillmark is now deploying from Fund II.

Stillmark invests in teams tackling fundamental problems at the base of the systems they operate in: money, energy, AI, and the infrastructure that connects them. We partner with founders in industries of critical economic relevance, building companies meant to last generations. Hard problems, serious markets, no nonsense.
Founded Stillmark in 2019 after investing at venture firms in Los Angeles and New York, focused on infrastructure and enterprise technologies, including frontier data and cloud infrastructure, as well as commerce technologies. Has worked alongside Bitcoin founders and core developers since 2013.
Joined Stillmark full-time in 2021 after 12 years in AI research and engineering at X, SandboxAQ, and Heal, where he led AI and machine learning before its acquisition by Humana. Holds a 2021 patent on ML-driven gene discovery and gene editing in plants (US20220301658A1).
