Score Rationale
Stralis has minimal credible signal for defense-specific investment despite YC pedigree. No named founders with defense or aerospace expertise are evident, no government contracts or pilot customers are mentioned, and hydrogen-electric propulsion is a crowded aerospace space (Airbus, Heart Aerospace, ZeroAvia all ahead). While emissions-free aviation aligns with DoD sustainability goals (SECDEF climate priorities), the company shows no evidence of defense customer pull, military specification targeting, or meaningful capital deployment relative to the ambitious hardware challenge—making this a consumer/commercial aerospace play that happens to mention defense, rather than a defense-first company.
