Leo Ringer is the Founding Partner of Form Ventures, an early-stage London-based venture capital firm he launched in 2019 after more than a decade in public policy, including roles at the CBI and advising the UK Secretary of State for Business. His investment thesis targets pre-seed and seed startups in markets shaped by public policy and regulation, focusing exclusively on the United Kingdom. The firm manages over £30m and typically provides early-stage funding alongside regulatory guidance to help founders navigate policymaking. While specific check sizes and lead/follow behavior are not publicly detailed, Form Ventures has made 31 investments, including a February 2026 round in Lifted and holds one exit, Ophelos, which departed in September 2023. Notable portfolio companies include Lifted and the exited Ophelos, though a broader list of named companies beyond these two is not explicitly confirmed in available sources. Ringer distinguishes his approach by uniquely helping UK tech companies understand and navigate policymaking, a capability he notes is rare for VC funds outside the US. He regularly writes and speaks on the intersection of tech
