Razor’s Edge Ventures

Razor's Edge Ventures is a Reston, Virginia-based multi-stage venture capital firm founded in 2011 that invests in high-growth technology companies at the intersection of the national security community and commercial enterprise markets. The firm is one of the most prominent defense and national-security investors in the United States, backing companies across space, autonomy, cyber, advanced sensing, signal processing, AI-enabled systems, aerospace and defense, maritime platforms, and enterprise infrastructure. Three co-founding Managing Partners lead the firm: Mark Spoto, who brings 25 years of engineering, law, and corporate-transactions experience; Jack Kaskaras; and Peggy Styer. Razor's Edge leads rounds across the full investment lifecycle, from Seed through Series C and beyond. The firm closed Fund III at roughly $340 million in September 2022, exceeding its $250 million target, and most recently closed Fund IV at $560 million in September 2025, exceeding a $400 million target — bringing total AUM into the upper tier of dedicated defense-focused venture managers. Across 55 total investments, notable portfolio companies include 908 Devices (handheld mass spectrometry, Nasdaq IPO), HawkEye 360 (RF geospatial analytics), BlackSky (geospatial intelligence, Nasdaq IPO), X-Bow Systems (solid rocket motor manufacturing), BlackSea Technologies (maritime platforms), Corsha (machine-identity cybersecurity), and Integer Technologies (AI-driven cyber, sensing, and autonomy software). The firm made 7 investments in 2025 alone. Razor's Edge differentiates itself through deep relationships with the national security community — including defense prime contractors, government agencies, and classified program offices — that help portfolio companies navigate procurement cycles and achieve mission-critical customer adoption faster than commercially oriented investors could facilitate.
