SAN FRANCISCO--(BUSINESS WIRE)--Sep 30, 2025--
Longeye, developer of AI-powered investigative tools for law enforcement and the justice system, today announced it has raised $5 million in seed funding led by Andreessen Horowitz's American Dynamism Fund. The company simultaneously announced the successful deployment of its platform with the Redmond Police Department, where detectives have already used the technology to surface previously buried evidence in active investigations.
Founded by former Skydio GTM leader Guillaume Delepine, Longeye addresses a critical challenge facing modern law enforcement: the overwhelming volume of digital evidence in criminal cases combined with a stark reality—in 2024 only 44% of violent crimes and 16% of property crimes were solved nationwide. Meanwhile, 70% of investigators report that they lack the time to go through all the digital evidence for their case work.
“America is desperate for a safer society that still protects civil liberties, but we will never get that until the justice system moves at the speed of crime,” said Guillaume Delepine, founder and CEO of Longeye. “The biggest lever we have to deter crime isn't the severity of punishment—research consistently shows it's the certainty of being caught that prevents criminal behavior. When criminals believe they’ll be caught and prosecuted, they don’t commit the crime in the first place.”
Longeye’s platform uses AI to analyze and prioritize overwhelming volumes of audio, video, and thousands of pages of documents while maintaining strict FBI compliance requirements and linking all findings to verifiable source material. In its initial deployment with Redmond Police Department in Washington, detectives uploaded more than 2,000 files within the first day. The platform identified a confession-like conversation buried in jail call recordings that had previously gone undetected, leading officers to the location of a spent shell casing that effectively closed the case—demonstrating immediate operational value in active investigations.
The seed round was led by Andreessen Horowitz’s American Dynamism fund, with participation from Seven Stars Capital and strategic angels including Adam Bry and Abe Bachrach (founders of Skydio), Seth Forsgren and Hayk Martiros (founders of Producer AI), Nate Robert (founder & CEO of Baton), Kevin Mullins (CEO of SaferMobility), Macario Namie (CMO, Skydio), Anna Birch (VP People, Skydio), John Bautista (partner, Orrick) and Geoff Caldwell (retired Captain, San Bruno PD), along with other law enforcement professionals and industry leaders.
"The explosion of digital evidence represents both an opportunity and a crisis for law enforcement," said David Ulevitch, General Partner at Andreessen Horowitz. "We've backed companies like Skydio, Flock Safety, and Prepared 911 because we believe technology can fundamentally improve public safety. Longeye's approach—combining advanced AI with rigorous verification standards—enables investigators to leverage this data effectively while maintaining the integrity required for criminal proceedings."
Longeye's platform delivers government-grade security and capabilities built for the needs of detectives and investigators:
- Multi-format analysis: Audio, video, images, documents, and social media data
- Relevance ranking: Surfaces the most critical evidence first based on case context
- Verifiable citations: Every summary links back to original source material
- Secure hosting: Self-hosted on AWS GovCloud (used by the FBI); no third-party APIs
- Language support: Real-time translation and transcription in Spanish, Mandarin, and more
- Privacy by design: Models never train on case data; each investigation is fully isolated
- Rapid search: Query thousands of hours of content and get results in seconds
The impact is already visible on the ground in Redmond, where detectives are experiencing dramatic time savings on active cases.
“In Redmond, we face the same challenges as larger jurisdictions, but with fewer people to manage the workload,” said Chief Darrell Lowe, Redmond Police Department. “As a premier law enforcement agency, Redmond is committed to staying ahead of the curve when it comes to public safety technology. Longeye has already proven its value, cutting months off investigations, surfacing leads we might have missed, and even closing gaps in a cold-case homicide. Every hour Longeye gives back to my detectives is an hour invested in solving cases, supporting victims, providing closure and strengthening community trust.”
The funding will support product development, expansion of the engineering team, deployment to additional law enforcement agencies, and the development of tailored solutions for prosecutors and public defenders. As part of its commitment to balanced justice, Longeye plans to provide AI services free of charge to public defenders' offices.
"Law enforcement has always faced impossible trade-offs—you can be fast or you can be thorough, you can cast a wide net or preserve privacy, you can solve cases or respect resource constraints," Delepine added. "AI changes that calculus entirely. Now we can process massive datasets while being more targeted about what investigators actually review. We can finally move faster without sacrificing truth or privacy."
