Shield Capital was founded by Philip Bilden and Raj Shah, who began planning the firm together in 2015 around cybersecurity seed investments before formally launching it in 2021. Bilden brings more than two decades as a Managing Director at HarbourVest Partners, a private equity firm managing over $100 billion, plus deep U.S. Navy family ties spanning four generations; Shah is a former F-16 fighter pilot who led the Defense Innovation Unit, the Pentagon's flagship technology innovation organization, across both the Obama and Trump administrations. That combination of institutional investing credibility and direct national-security operating experience shapes Shield's specific thesis: back dual-use companies serving both commercial and defense customers in AI, autonomy, cybersecurity, and space, operating in strategic partnership with L3Harris Technologies. The firm's advisory board includes former Defense Secretary Ash Carter and former National Security Advisor H.R. McMaster, and its debut fund closed oversubscribed at $186 million, 55% above target.
No confirmed exit yet - Shield's clearest proof point is its oversubscribed $186 million debut fund, closed 55% above target, and its strategic partnership with L3Harris Technologies to pursue dual-use defense and commercial technology investments
