Alyse Killeen

Alyse Killeen is the GP and Managing Partner of Stillmark and is focused on the Firm’s investments. With close to 10-years of experience identifying and investing in frontier technologies, Alyse founded Stillmark to focus solely on investments in innovation in the Bitcoin ecosystem. In 2013 Alyse entered the Bitcoin industry as one of the first institutional investors to study the potential of Satoshi Nakamoto’s invention. Her first investments in the field were made in 2014 and include the initial financing for Blockstream, a now unicorn company for which she serves as a Board Director. Alyse is also on the boards of Satoshi Energy and IBEX Mercado.

The Bitcoin blockchain and Bitcoin’s Lightning Network are applicable across sectors, geographies, and demographic groups. In kind, Alyse organized and manages Stillmark as a generalist fund with specialty competence and expertise in Bitcoin technologies. Alyse believes that Stillmark can consistently and sustainably identify large-scale investment opportunities in the private market, across sectors, that are either freshly unlocked or advanced by Bitcoin technology and/or bitcoin the digital, bearer asset.

Stillmark is differentiated as a Bitcoin-dedicated fund in that it is developed on a foundation of experience and insight in both the traditional practice of venture capital and in the technologies that define the firm’s mandate. Prior to Stillmark, Alyse was on the investment teams of Los Angeles-based venture capital firms Clearstone Ventures Partners and March Capital Partners, concentrated in part on data science, cloud networking, and cybersecurity technologies as they emerged.
