About Investor

David Rothzeid is a Principal at Shield Capital, leaning into early-stage defense and security themes where “product-market fit” often means “operator trust + deployment reality.” Typical stage focus: seed through Series A, with an eye for dual-use companies that can win in commercial markets and still matter in the national-security stack. Typical check range: $100K–$5.0M. Background-wise, he’s been positioned close to the defense innovation ecosystem, which usually translates into sharper judgment about procurement friction and real-world constraints.
