Icon Ventures describes itself as "Foundational VC for AI," building on two decades investing in technically deep areas like cybersecurity and digital health, and it typically leads Series B and C rounds in companies such as Palo Alto Networks, FireEye, Proofpoint, Bill.com, and Teladoc after they've proven their product but before they dominate their market. The firm stays intentionally small and tightly integrated, with added teams in Dublin and Tokyo, and it runs a Canadian Engineering Talent Program that gives portfolio companies a dedicated in-house recruiter to help build engineering teams in Canada.
