Analysis
Watchtower Labs emerged from stealth with $35 million in seed financing led by Shield Capital and Conviction, with Founders Fund also participating, according to Pulse 2.0. The company builds AI decision software for military leaders and planners, starting with logistics and sustainment planning, using AI, simulation and optimization to model operational futures while keeping human decision-makers in control of final actions.
Watchtower was incubated inside Shield Capital itself, and the fund's founder, Raj Shah, serves as the startup's chairman -- a structure where the lead investor also built the company before the round. CEO Akhil Iyer is a former Marine special operations officer and a former Shield Capital investor; co-founders Souren Aghajanyan and John Morman previously led engineering teams at Microsoft.
A government customer before the round closed
Before this seed round was announced, Watchtower had already secured a meaningful government relationship: the Defense Innovation Unit selected the company in January 2026 under the Joint Sustainment Decision Tool program, and the company has worked with the Naval Postgraduate School since 2025. That sequencing -- government traction first, headline funding second -- is unusual for a seed-stage defense startup and suggests Watchtower's cap table is being built around a product that already has a foothold inside the Pentagon's innovation pipeline rather than a pitch deck alone.
Watchtower's approach sits alongside a broader wave of venture-backed defense AI companies, including Anduril and Shield AI, both of which have raised at multibillion-dollar valuations on hardware-plus-software bets, and Palantir, whose government-facing decision software set the template this category still follows. Watchtower's bet is narrower and earlier-stage: logistics and sustainment planning specifically, rather than the broader battlefield-autonomy pitch that has drawn the largest checks in defense tech this year.
Founders Fund's participation alongside Shield Capital and Conviction adds a recognizable name with a long history of early defense-tech bets, including Anduril. For Watchtower, the test ahead is whether the Joint Sustainment Decision Tool contract converts into a larger program of record -- the kind of multi-year government commitment that would justify the next round's valuation far more than the $35 million seed itself.
