Anduril alumni launch new defense tech startup with backing from Andreessen Horowitz and Point72 Ventures

- Rune, a defense tech startup, raised $6.2 million in seed funding led by Andreessen Horowitz.
- Founded by former Anduril employees, Rune develops software to manage military field logistics.
- Investors are increasingly backing defense tech startups to modernize military capabilities.
Rune, a defense tech startup based in Roslyn, Va., emerged from stealth Wednesday with $6.2 million in seed funding. Andreessen Horowitz led the round. Point72 Ventures, XYZ Venture Capital, and several defense industry executives, including Anduril's senior VP of software engineering Gokul Subramanian, participated.
Founded in 2024 by former Anduril employees David Tuttle and Peter Goldsborough, Rune is developing software to help the military manage field logistics. The current process of deciding whether a particular unit needs more food, fuel, or ammunition is "almost entirely a manual, human-centric process" that "runs off Excel spreadsheets," Tuttle, cofounder and CEO of Rune, told Business Insider.
TyrOS, Rune's software named after the Norse god of war Tyr, gathers data manually tabulated by frontline units. It then autonomously tracks supplies such as food or equipment, predicts future resupply needs, and helps the military determine when and where to restock, especially for resourceβand location-constrained environments. An AI model that Rune is currently building enables its predictive modeling capabilities, but the company is also having initial conversations with "larger AI providers" to explore potential partnerships, Tuttle said.
The 11-person company has developed a prototype of the software, which "has already been in the hands of actual warfighters" in training exercises, Tuttle said. While Rune's software currently relies on manual data entry, TyrOS can integrate with government-owned software to automate logistics data collection, a capability that could become increasingly standard as other defense tech companies develop such technologies.
While several companies manage commercial logistics, TyrOS is built for the unique challenges of military operations. Rune is developing the software to work in areas with limited or disrupted communication, known as DDIL environments. It also enables military units to share data with each other, ensuring connectivity even if one unit's connection is compromised.
In recent years, investors in Silicon Valley have increasingly doubled down on defense tech startups, reflecting a growing commitment to companies hoping to strengthen national security and modernize military capabilities. "What we're seeing is a moment in time where technology can shift the balance between countries," Chris Morales, a partner at Point72 Ventures who also served in the US Navy for eight years, said. "And we're seeing teams that can actually take advantage of the moment."
Defense contractors and startups are also building in the military logistics space. Lockheed Martin, for example, develops battle management and equipment logistics software. Adyton, another startup, is working on mobile tools to streamline communication about equipment and other needs across the military.
Before cofounding Rune, Tuttle led the command and control hardware business at Andruil, where he met cofounder and CTO Peter Goldsborough. Tuttle previously worked at the Joint Special Operations Command, a special missions unit, and in investment banking at Citi. He also served as a field artillery officer in the US Army.
Goldsborough also worked in command and control at Anduril, where he was a chief engineer.
"We spent a lot of time on what we say, how do you fight the force?" Tuttle said. "But equally important and more so, even now is, how do you sustain the force? How do you keep the force fighting past the first day, two days β past the first 72 hours in an actual conflict?"
Almost a year into building the company, the cofounders will use Rune's new funding to continue building out its engineering, business development, and product teams, Tuttle said.
"July Fourth was actually our first official day as Rune employees, which is pretty cool," Tuttle said. "We've been off to the races since."
