At Longeye, we're taking
a stand for truth.

We think like detectives. And build like engineers.

Longeye is an AI-powered investigative workspace that helps law enforcement agencies make sense of massive volumes of digital evidence up to 100x faster. Every day, investigators face thousands of hours of video, audio recordings, messages, and images that need to be reviewed.

In the field, that speed changes what is possible. We've seen a single detective's pilot grow into 80 fellow investigators using Longeye without prompting. We've seen an investigator close three cases in her first three days with the product.

We've also seen the truth inside digital evidence change the course of serious cases, including child-abuse investigations where confessions helped dismantle the defense. Our customers' work has earned national media attention because when investigators can find the truth faster, the justice system can move with greater confidence.

Investigation

What drives us

Balanced Justice

We're committed to strengthening the integrity of the justice process for all. As part of this commitment, Longeye plans to provide AI services free of charge to public defenders' offices.

Built With Investigators

We're a team that listens to the people we create products for. Longeye is the product of working side-by-side with police on the ground to find real solutions.

Privacy First

Our AI models never train on case data and every investigation remains fully isolated. We built our security from the ground up with defense in depth.

Engineering excellence committed to public safety.

While Guillaume was helping Skydio grow from serving zero to 650 public safety agencies, Dani was leading a massive engineering team to commercialize the ubiquitous core platform for Apollo GraphQL. Now these childhood friends are teaming up to make AI happen for law enforcement.
