Company Spotlight: Longeye

Longeye moves like an investigator wired to the pulse of a case, scanning the digital noise that buries truth before detectives even hit the scene. Clearance rates sit at 44% for violent crime and 16% for property crime, not because cops lack skill but because evidence now scales like a tidal surge. Hours of jail calls, terabytes of video, stacks of documents and social posts form a maze no human can fully chase. Longeye, built in SF by Guillaume Delépine and Dani, steps into that gap with a platform shaped by field grit and engineering precision, turning overload into opportunity the moment a file lands.

Guillaume Delépine felt the fracture personally when his SF apartment was broken into and the case vanished under backlog. Six years at Skydio put him on the ground with first responders, where he learned what actually slows justice. Princeton and Harvard Kennedy School refined his lens, but real pressure taught him the difference between tech made for demos and tech that matters at 3 a.m. Dani brings the counterforce, an MIT-trained builder who spent 9 years scaling Apollo GraphQL from 20 people to 200+. She led a 40-person Core Platform org that kept pace with some of the fastest product cycles in the industry, sharpening the instincts needed to build systems investigators can trust at full speed.

Longeye ingests audio, video, images, docs and social data, processes it up to 100x faster than a human, and ties every insight back to source with court-ready clarity. It acts like an AI chief of staff, not replacing judgment but accelerating it. In Redmond, detectives uploaded 2,000+ files on day one and uncovered a buried jail-call conversation that led them to a spent shell casing central to closing the case. The platform surfaced confessions hidden in hundreds of audio files and confirmed details in a homicide investigation within minutes. Chief Darrell Lowe said Longeye has already cut months off timelines and reopened gaps thought permanently cold.

Investors moved quickly. a16z’s American Dynamism Fund led a $5M seed round with Seven Stars Capital and strategic voices from Skydio, Producer AI, Baton, SaferMobility and others including Anna Wiesenthal-Birch and Macario Namie. Their thesis is simple. Evidence volume is exploding, AI is finally mature enough to treat it with forensic-grade verification, and low clearance rates require a new kind of force multiplier. Longeye answers with CJIS-compliant infrastructure, no 3rd-party APIs and models that never train on case data, serving law enforcement, prosecutors and public defenders at no cost to preserve balance.

The team ships like the mission depends on it, 200+ pull requests a month from 5 engineers. If you want to build tech that moves with the speed of crime, step into the work that moves justice forward.
