According to the announcement, the investment round was led by First Round Capital and had the participation of other investors such as Lux Capital and  Y Combinator.

Theseus announced it raised $4.3 million in a seed funding round this Thursday. The founders went viral on X last year after sharing their hackathon achievement on X. The company will use the new investment to keep developing  Micro VPS, a system that allows drones to fly autonomously without a GPS signal.

“We’re rapidly developing solutions to urgent operational needs by engaging directly with operators and iterating at the pace of a tech company,” states the post. “GPS jamming is the first defense problem we’ve solved, but this is just the start.” According to TechCrunch, the young founders of Theseus went viral on social media last year, after one of the three, Ian Laffey, shared a post on X showcasing its team’s achievement during a hackathon of building a drone for less than $500 that could fly without a GPS signal.

The system, designed by Carl Schoeller, Sacha Lévy, and Laffey—all under 25 at the time—, offers an important solution in the industry by making it possible for drones to fly autonomously using just Google Maps and a camera. After the viral post in February 2024, the three engineers applied for Y Combinator, joined the Spring 2024 cohort, and founded the San Francisco-based company. Theseus’s main product is its Micro Visual Positioning System (VPS), which considers current hardware and software technology to build cheap and efficient drones. “Micro VPS works by looking at the ground and comparing camera images to a large database of satellite maps stored onboard,” wrote the team in the announcement. “By correlating features between the two, our Micro VPS accurately determines the drone’s position and relays that information just like a regular GPS.” The team has been working in collaboration with the United States Special Operations Command and operators who can deploy the system. With the new funding, the company will be able to hire new talent, expand, and keep developing Micro VPS. Other countries like China have also been developing drone technologies in multiple fields, such as the use of drones for cloud seeding, and Ukraine has been using drones to collect data to train AI-powered systems.
