The Bitcoin Policy Institute lists Zell as its President, at the top of a core team that includes an executive director, a managing director and heads of policy, research and government affairs. The organisation states that it was established in 2021 and is a registered 501(c)(3) non-profit with EIN 88-1567390.
Its published profile of him does not carry an extended biography, listing instead the volume of material he has authored or co-authored for the institute: quarterly reports, commentary, policy briefs and podcast appearances. BPI's own description of its work is research and education on Bitcoin specifically, presented as non-partisan and aimed at policymakers, and Zell's output sits inside that remit rather than alongside it. The directory records only what the organisation publishes about him.
