Excerpt from the original posting

Vannevar builds AI systems for the Department of War's most consequential missions. We have 125 deployments across every branch and combatant command spanning our core platform and five distinct products. An an example of how we work, when major combat operations started with Iran, we fielded a new product supporting 24/7 operations and 9,000+ users in three months.

We focus on embedding directly with operational units supporting great power competition with China, combat operations with Iran, and counter-narcotics missions.
