Picogrid has raised $45 million in a Series A led by Bessemer Venture Partners, with Washington Harbour and GSBackers joining alongside existing investors Initialized Capital, Starburst Ventures, Credo Ventures, Giant Step Capital, and Alumni Ventures. The El Segundo, California company builds the software and edge hardware that connects drones, sensors, radars, C2 interfaces, and autonomous platforms across the fragmented ecosystem of modern military procurement.

The bottleneck

The Pentagon is acquiring autonomous systems, edge compute, EW payloads, space systems, and AI models faster than it can integrate them. Each new platform arrives with its own data format, communication protocol, and command interface. Operators in the field end up managing one-to-one relationships with individual systems rather than a unified operational picture. Picogrid's position is that integration, not invention, is now the binding constraint and that the answer is a neutral, vendor-agnostic middleware layer built once for the ecosystem rather than rebuilt mission by mission.

Product stack

Legion is Picogrid's core platform: an API-first data layer that connects and commands mission assets, streams sensor data, tasks unmanned systems, and bridges third-party C2 interfaces including ATAK. Orion is the browser-based command interface that sits above Legion, providing live sensor feeds, AI overlays, and configurable dashboards for controlling autonomous systems in the field. The Expeditionary C2 Node family, Lander, Helios, and Portal, provides the rugged edge hardware layer: power, compute, and connectivity for austere environments where cloud infrastructure is unavailable or unreliable. Lander is built for long-duration stationary operations; Helios is designed for mobile frontline deployment. Legion runs across all three, which means the integration layer moves with the mission rather than remaining fixed at a base.

Picogrid's stated integration ecosystem now spans more than 100 defense systems, including Skydio, Northrop Grumman, Echodyne, CX2, and Neros. The company also participates in the U.S. Space Force's R2C2 program, a $999 million IDIQ effort to modernize satellite ground systems, delivering modular, cloud-ready software for space operations interoperability. Program ceiling figures are not revenue; they indicate procurement access and contract vehicle validation.

Contract trail

Picogrid arrived at its Series A with a documented contract progression across Air Force, Army, and Space Force programs. In April 2025, the Air Force awarded a $2.7 million contract for next-generation C2 modernization. The Army followed in June 2025 with a $1.1 million Legion deployment contract to connect siloed military systems. A $3.2 million Air Force award in September 2025 covered unmanned-systems integration using Legion and Helios.

The company's largest publicly disclosed contract at the time, a $9.3 million Air Force SBIR Phase III award announced in February 2026, funded Legion-based counter-drone integration at selected Air Force bases, connecting sensors, jammers, and base-defense systems through what Breaking Defense described as "translator" software. A joint contract with Guardian RF at Vandenberg Space Force Base, also in February 2026, addressed drone-defense requirements around sensitive launch infrastructure.

In April 2026, Picogrid won a contract with the XVIII Airborne Corps for battlefield-system integration focused on counter-UAS, and the Army's Joint Innovation Outpost deployed Picogrid technology in contingency operations, moving from procurement to forward deployment in fewer than 90 days. In May 2026, Picogrid joined the Army's Right to Integrate sprint at Fort Carson. FedRAMP High Authorization, received in March 2026, cleared Legion for federal deployments handling sensitive unclassified data.

Founding context

Zane Mountcastle and Martin Slosarik began building defense technology more than a decade ago as Army contractors, where they encountered the same integration fragmentation the company now addresses commercially. Mountcastle has described the core problem as operators being told "we don't have access to that" across systems that were theoretically on the same side. Picogrid formally launched from those contractor years and raised a $12 million seed in early 2024, at which point the company already claimed more than a dozen federal contracts and active usage by Ukraine's Ministry of Defense. The Series A, announced May 29, 2026, follows that seed by roughly 27 months and scales production across California, Oklahoma, and other U.S. locations.

David Cowan at Bessemer, whose prior defense bets include Breaker and DEFCON AI alongside earlier positions in Rocket Lab and Anthropic, described Picogrid as having built "connective tissue" across military systems and said Bessemer views the company as on a path to become the next integration prime, a position between a software company and a defense prime that owns the layer other systems plug into rather than building those systems itself.

What the record does not yet show

Named recurring revenue customers, contract-specific booking figures, and deployed unit economics are not publicly disclosed. IDIQ ceilings and SBIR awards establish procurement access and technical validation; they do not confirm commercial scale. The "integration prime" framing is an investor thesis stated at Series A, not a market outcome. Whether Picogrid can hold a vendor-neutral position as larger primes build competing integration layers e.g Anduril's Lattice, Palantir's Maven is the structural question the contract trail does not resolve.
