Picogrid secures $45M to establish itself as the neutral integration layer for contemporary defense.

      The Pentagon is acquiring defense hardware more rapidly than it can ensure interoperability among the various systems. With an influx of sensors, autonomous platforms, edge computing, electronic warfare payloads, space, and underwater systems, each operates in its own unique language. Picogrid, a company established six years ago in El Segundo, California, has secured $45 million in funding to bridge this communication gap.

      The Series A funding, which was announced on Thursday under embargo, was led by Bessemer Venture Partners, with Washington Harbour and GSBackers participating alongside existing investors such as Initialized Capital, Starburst Ventures, and the Czech fund Credo Ventures.

      This new funding follows the company's $12 million seed round completed in early 2024 and arrives as investment sizes in defense technology continue to increase.

      Picogrid argues that integration has become the limiting factor in military effectiveness, rather than invention. A force may possess the best drone and radar available, yet still face challenges in integrating these technologies into a command network that wasn't designed to accommodate them.

      The company positions itself as the “open integration layer,” taking a neutral stance: it creates a solution designed for the entire ecosystem rather than being rebuilt for each specific mission. According to Picogrid, this ecosystem now encompasses over 100 defense systems from various vendors, both established and emerging, including Skydio, Northrop Grumman, Echodyne, CX2, and Neros. The diversity of this mix is crucial since manufacturers of drones and prime contractors seldom collaborate to ensure interoperability, ultimately costing the field operator.

      “The systems are improving, but the connections between them aren’t keeping pace,” remarked Zane Mountcastle, Picogrid’s co-founder and CEO, who previously developed early autonomous systems as an Army contractor before founding the company. “Field operators are facing this issue daily, and our goal is to alleviate that burden.”

      Mountcastle indicated that the funding would be used to scale production in California, Oklahoma, and other locations to meet the demands of US forces and their allies.

      Bessemer’s interest aligns with its strategic direction. David Cowan, the partner overseeing the deal, has spent recent years building a defense technology portfolio that includes companies like Breaker and DEFCON AI, along with earlier investments in Rocket Lab and Anthropic.

      “With the proliferation of autonomous systems across all domains, the need for a hardware-agnostic and interoperable infrastructure layer is evident,” he stated, referring to Picogrid as “on track to become the next integration prime.”

      This assertion carries significant implications. The integration primes of the previous era were the system houses that connected the platforms of their time, and the term is not easily given in the procurement landscape. Picogrid has not revealed a valuation for this funding round, nor its employee count or revenue, leaving the gap between interoperability and becoming a prime contractor largely dependent on trust at this stage.

      However, the trajectory of funding is clear. European defense tech investment reached a record high last year and has continued to increase into 2025, with an even greater demand emerging from the US.

      Picogrid is betting that the next decade will see a surge in systems, vendors, and networks that exceed the capacity of the traditional integration model, positioning a neutral entity as necessary to maintain cohesion among them.
