## Questions

### Who runs investment decisions at Stillmark?

Founder and Managing Partner Alyse Killeen leads all investment decisions alongside Partner Vikash Singh. Killeen has operated in the Bitcoin venture and policy landscape for over a decade and sits on the boards of several portfolio companies. The firm maintains no investment committee outside this partnership.

### How does Stillmark source proprietary deal flow?

Sourcing is thesis-driven and deeply embedded in Bitcoin developer communities. Killeen's longstanding relationships with core protocol contributors, open-source working groups, and Bitcoin-focused policy circles surface founders who are building on Bitcoin's base layer and Lightning before they seek broader venture attention. The firm generally avoids deal-flow sourced through crypto-wide demo days.

### Does Stillmark invest in tokens or non-Bitcoin crypto networks?

No. Stillmark invests exclusively in equity of companies building on or in service of Bitcoin. The firm does not purchase tokens, participate in protocol treasuries, or back projects native to other blockchains such as Ethereum or Solana, even for hedging purposes. This constraint is fundamental to its mandate.

### What investment stages does Stillmark typically target?

Stillmark focuses on seed-stage rounds, often as the first institutional capital into a company. It will also participate in early-stage follow-on rounds for existing portfolio companies when the capital structure and milestone achievement warrant continued concentration.

### Has Stillmark disclosed its fund size or limited partners?

Stillmark has not publicly disclosed assets under management, fund size, deployment totals, or the identities of its limited partners. The firm runs a deliberately low-profile operation without published performance benchmarks or vehicle documentation in public databases.
