Surtr raises $4.8M seed to unify counter-drone systems on one screen
Surtr, a Y Combinator Spring 2026 startup, has raised a $4.8 million seed round to build software that combines the sensors, command tools, and effectors used in counter-uncrewed aerial systems (c-UAS) into a single interface. The round was led by Allegis Capital, Eniac Ventures, Gaingels, Robinhood Ventures, and Streamlined Ventures.
The pitch is simple: operators trying to take down drones should look at one screen, not fourteen. Surtr adds a software and data-fusion layer that pulls feeds from radars, cameras, turrets, interceptors, and electronic warfare systems into what co-founder Anshul Ahluwalia calls "a single pane of glass."
The company is also building an autonomy layer on top. The idea is that the system could automatically cue a defensive response — such as a machine gun turret — against an incoming aerial threat.
"There's been a huge stockpile of both sensors and effectors dedicated to detecting and feeding drones, but there's no good way to integrate all of those into one platform," Ahluwalia said. "Operators right now are stuck staring at a wall of screens."
Founded in March 2026, Surtr is run by defense-industry veterans. Ahluwalia was an integration and autonomy engineer at Shield AI, and co-founder Cameron Fiore worked at Shield AI and Anduril.
The two found that plugging third-party hardware into platforms like Anduril's Lattice was harder than working with in-house kit. "These software stacks, like Lattice and Hivemind, were very tailored towards custom hardware built by those companies themselves," Ahluwalia said.
Surtr plans to use the money to expand its team, submit for Pentagon programs, and secure an ITAR license to export to countries including Ukraine. It has already tested its software with military operators after being contacted by Brave1, Ukraine's defense-tech innovation body.
Surtr enters a crowded field. Companies like Picogrid already focus on making disparate c-UAS systems communicate, and the incumbent platforms Surtr wants to plug into are built by well-funded giants like Anduril.
The round underscores how far Y Combinator's output has shifted, with defense integration replacing consumer apps as a magnet for early-stage capital. As militaries stockpile counter-drone hardware faster than they can operate it, the bottleneck is moving from kit to software — and investors are betting on the layer that ties it all together.
