Gabriel is Co-Founder and CEO of Streamline Systems, a Y Combinator-backed startup building a low-cost navigation module that replaces GPS for drones and military platforms.

Gabriel was a Senior Software Developer at Torus, a p2p protocol for AI agent swarms, and studied Aerospace and Information Engineering at Cambridge before leaving to go full-time on the startup. He also built a content agency that scaled faceless creators to billions of views across 10 languages using custom Premiere Pro automation.

Gabriel left Cambridge against advice, moved back in with his parents with about 15K GBP to his name, and kept building after a YC S26 rejection. He was down to his last 1K GBP, enough for a few more drone crashes, by the time his YC interview came around.

Streamline Systems joined Y Combinator's F26 batch, and PitchBook lists $500K raised from Y Combinator. Gabriel co-founded the company with Charlie Jessett, who serves as COO.

Streamline's drop-in module works with ArduPilot, INAV and PX4 flight controllers and has demonstrated satellite-independent autonomous flight with GPS handoff. The company is working with defence and PNT partners across the US and Europe to remove satellite dependency.
