Notable Investments
SYN Ventures is the only CISO-founded cyber VC with two former Fortune 500 CISOs as full-time founding partners, backed by an unusually heavyweight bench of cyber operators as venture partners that leads other VCs to actively pull SYN into cyber rounds to add operator depth. The fund runs two distinct vehicles under one brand so founders can stay with a single, deeply specialized capital partner from seed through growth, while using its CISO network to materially drive revenue for portfolio companies through introductions and go-to-market support that often represents a material portion of new ARR in the first 12-24 months after investment.
