In a remarkable tale of innovation and serendipity, a viral tweet about a hackathon project has led to a $4.3 million seed funding round for Theseus, a San Francisco-based startup that's developing GPS-free drone navigation technology. The company, founded by three engineers who met at a hackathon, aims to combat GPS jamming issues in military drones, particularly in conflict zones like Ukraine.

The story began on February 18, 2024, when Ian Laffey posted on X (formerly Twitter) about a drone he and his colleagues, Sacha Lévy and Carl Schoeller, built at a hackathon. The drone, which cost under $500, used its camera and Google Maps to calculate its coordinates, eliminating the need for GPS signals. The tweet went viral, catching the attention of investors and military organizations.

The trio, all engineers under the age of 25, decided to apply to Y Combinator's Spring 2024 cohort, and were successfully accepted. This led to the formation of Theseus, with Schoeller as CEO. The company's technology has significant potential to address the issue of GPS jamming, which has plagued drone operators in Ukraine, forcing them to rely on high-tech goggles for navigation.

Theseus joins a growing flock of drone-related startups, including Skydio, Shield AI, and Anduril, which have collectively raised billions of dollars in funding. However, Theseus differentiates itself by focusing on the hardware components and software that enable military drones to fly unmanned without GPS, rather than building targeting systems or drones themselves.

While Theseus has not yet secured any U.S. military deals or been deployed in an actual battlefield, the company has entered into an agreement with U.S. Special Forces for early testing and development. A recent photo shared with TechCrunch shows the system in action at a secret Special Forces base.

The $4.3 million seed funding round, led by First Round Capital, with additional backing from Y Combinator and Lux Capital, will be used to further develop the technology and hire for three engineering roles. Theseus's rapid progress is a testament to the power of innovation and collaboration, as well as the potential for hackathons to spawn groundbreaking ideas.

In a LinkedIn post, Schoeller reflected on the unconventional origins of the company, noting that starting a business with people you've known for under a week "generally isn't advised." However, in Theseus's case, the leap of faith has paid off, and the company is poised to make a significant impact in the drone technology space.

As the drone industry continues to evolve, Theseus's GPS-free navigation technology is likely to play a critical role in shaping the future of military drone operations. With its innovative approach and significant funding, the company is well-positioned to tackle the complex challenges of GPS jamming and provide a critical advantage to military forces around the world.
