ARMADIN , the cybersecurity startup founded by Kevin Mandia, has announced a funding round of $189.9M covering Seed and Series A as part of its public launch, with the formal launch piece published on 10 March 2026. The round was led by Accel, with participation from Google Ventures, Kleiner Perkins, Menlo Ventures, In-Q-Tel, and follow-on investment from 8VC and Ballistic Ventures, and is described as the largest seed and series A funding in cybersecurity history.
Armadin positions itself as an AI-powered red teaming platform designed to emulate attacker methods at machine speed, with Mandia as CEO and co-founders Travis Lanham (CTO), Evan Peña (chief offensive security officer) and David Slater (chief architect). The company’s earlier quiet seed of $24 million was disclosed in late 2025, and Armadin intends to provide autonomous, AI-directed offensive security to close the agility gap against evolving threats.
According to SecurityWeek, the venture aims to combine elite red team expertise with AI to enable rapid identification of exploitable risk across networks.
