Vannevar Labs supports people on the front lines by building tools that deter and de-escalate conflict with America's adversaries. We build software and hardware for this mission that enable our customers to maintain maritime vigilance, disrupt misinformation, and collect non-traditional intelligence. In strategic competition, the intelligence and actions that shape conflict occur well before war itself. We build tools to win this fight now.
This mission has become urgent. The US and our allies are fighting a war of deterrence with woefully outdated technology. As a team, we believe in public service and that our democracy and government improve only if we put serious, collective effort into improving them, including the technology our government uses.
Since our founding in 2019, we have grown to support a wide range of missions and capabilities across all U.S. service branches, multiple combatant commands, partner nations, and the intelligence community. We have been profitable since 2021, and are backed by investors including General Catalyst, DFJ Growth, Point72, Costanoa, and Felicis.
