Sentinel Ventures

Managing Partners Ben Katz and Cameron Watts lead the firm and appear to share investment-decision authority. Partner David Magli and Directors Sean Plankey and Clif Triplett round out the five-person leadership team. Sentinel's website does not detail an investment committee structure or differentiate between sourcing, diligence, and approval roles within the group.

Sentinel exploits a narrow, policy-anchored mandate — securing the 16 critical-infrastructure sectors defined by the US government — to surface companies that generalist funds overlook. The team's operational backgrounds in cyber and infrastructure defense, combined with a stated network of global partners, suggest deal flow originates inside defense, intelligence, and industrial-operator circles rather than conventional venture pipelines. The firm does not publicly describe its sourcing mechanics in detail.

The firm's website describes only direct equity investments in early-stage companies. Sentinel has not publicly stated whether it makes fund-of-fund commitments, participates as an LP in other venture vehicles, or engages in co-investment structures. Without a public track record of fund commitments, the known posture is direct-deal only.

Sentinel does not publish a formal exclusion list, but its investment thesis effectively filters out any sector not encompassed by the US government's 16 critical-infrastructure categories. Consumer internet, entertainment, adtech, and other purely commercial software plays that fall outside CI security and resilience are absent from the stated mandate.
