What StillMark does
StillMark is a Bitcoin-focused early-stage venture capital firm founded in 2019 by Alyse Killeen in Los Angeles, operating as a distributed team of 2–10 professionals. The firm invests at the Pre-seed, Seed, and Series A stages, with initial capital commitments typically ranging from $250,000 to $3,000,000, and follows on in subsequent financings. StillMark's mandate is to back founders whose plans, products, and technologies advance Bitcoin's core principles—decentralization, self-custody, fungibility, and censorship resistance—and to serve as a long-term partner through subsequent rounds and across both favorable and unfavorable market cycles.
The firm's portfolio of 20+ companies spans the Bitcoin and Lightning Network stack, including Lightning Labs (payment infrastructure), Casa (self-custody and wealth management), Amboss Technologies (Lightning payment operations and routing), Meanwhile (Bitcoin-denominated life insurance), Gridless and Satoshi Energy (mining with renewable energy), Hoseki (proof-of-reserves), Voltage (enterprise Lightning node hosting), Alpen Labs (ZK rollups and smart contracts on Bitcoin), IBEX Mercado (Lightning-as-a-Service), Bitstack (Bitcoin savings app), Glimpse (Bitcoin prediction markets), and Striga (crypto and banking APIs for Europe). StillMark has also extended its thesis into AI/crypto convergence through investments such as Ridges (a Bittensor subnet for autonomous AI agent training).
StillMark generates returns through equity ownership in portfolio companies, benefiting from exits via acquisitions or public offerings, supplemented by standard venture fund management economics (management fees and carried interest on its funds). The firm is currently investing out of its second fund and reports a global investment scope. GTM is direct and founder-led: the firm proactively engages founders early—often before incorporation or departure from prior roles—and distributes capital through direct investment relationships supported by content marketing, conference presence (Bitcoin++, MicroStrategy Conference, Pacific Bitcoin), podcast appearances, and earned media (Bloomberg). Limited partner and detailed fund-level financial data are not publicly disclosed.
