William Green
Founder & CEO. Leads client strategy, runway planning, and coordination across every engagement.
WGF Group combines disciplined leadership, hands-on finance operations, and a global specialist network to help founders make better decisions before cash becomes a crisis.
William founded WGF Group to make high-caliber finance leadership accessible before a startup can justify a full-time finance team.
His approach draws on military leadership—clear priorities, accountable execution, and calm decisions under pressure—alongside international finance experience coordinating teams and partners across markets. The result is practical financial infrastructure founders can use, not reporting that arrives too late to matter.
