The Theseus founders met at the El Segundo hackathon, got into Y Combinator two weeks later, and flew their first GPS-denied drone navigation prototype two weeks after that. Today, just 7 months later, they've completed long-distance tests on base with American special forces. I got to sit down with Ian Laffey, Theseus CTO, to ask a bunch of technical questions about how the product works. (And he only had to tell me "sorry, that's a secret" one time.) I hope you enjoy the convo! Timestamps 00:00 — What is Theseus? 00:37 — What role does GPS play in modern conflict? 04:27 — What are the state of the art drones, and where did Theseus start? 07:35 — How did the company get started so quickly? 16:32 — How does GPS-denied drone navigation work? 21:56 — How can you defeat countermeasures & make the product resilient? ("If I say anything, my co-founders will kill me.") 24:11 — Why visual spectrum and not other sensors? 30:20 — Why is hardware so hard? 32:32 — How can you iterate quickly when building hardware? 38:21 — What's it like to build a hardware company as part of Y Combinator? 41:11 — What will Theseus demo before demo day? 42:27 — How do you move fast as a defense company? 47:30 — How well does the current prototype perform? 51:39 — What's next?
