Investment thesis
SYN Ventures invests in disruptive, innovative companies across cybersecurity, industrial security, national defense, privacy, regulatory compliance, and data governance. Founded in 2021 by a team of former CISOs, CEOs, CTOs, and founders with long careers in security, the firm invests from the earliest stages of company formation and enterprise traction through exit. Drawing on hundreds of years of combined security experience, the team aims to serve founders as an extension of their team, advising through the challenges of company and category building, and views its capital as the least valuable part of the partnership.
