Longeye, a startup building AI-powered investigative tools for law enforcement and the justice system, has announced the close of a $5 million seed round led by Andreessen Horowitz’s American Dynamism Fund. The company also revealed that its platform is already operational with the Redmond Police Department in Washington, where detectives used it to surface previously overlooked evidence—including a confession-like conversation hidden in jail call recordings that ultimately helped close an active case.
The company was founded by Guillaume Delepine, formerly of Skydio, who emphasizes that the fundamental deterrent to crime is not punishment severity but the certainty of being caught. This aligns with Longeye’s core mission: accelerating investigations by allowing detectives to process vast amounts of digital evidence—audio, video, images, documents, and social media—without sacrificing verification, compliance, or privacy. With violent crime clearance rates at 44% and property crime at just 16% in 2024, and with 70% of investigators reporting they lack the time to review all evidence, the need for such tools is immediate.
Longeye’s platform provides multi-format analysis, real-time transcription and translation, verifiable citations tied back to source material, and rapid search across thousands of files. Importantly, it runs on AWS GovCloud and avoids third-party APIs, ensuring compliance with FBI and federal security requirements. By design, its AI models never train on case data, and each investigation is isolated—giving it a “privacy by design” advantage in a sector where chain-of-custody and credibility are paramount.
The Redmond Police Department’s early adoption underscores both the urgency and effectiveness of this approach. Chief Darrell Lowe reported that the platform has cut months off investigations, uncovered leads that might have been lost, and even advanced progress in a cold-case homicide. For a mid-sized jurisdiction facing the same digital evidence overload as major cities but with fewer human resources, these efficiencies directly translate into safer communities and stronger trust between police and residents.
Andreessen Horowitz’s David Ulevitch contextualized the investment by comparing Longeye’s mission with other public safety startups like Skydio, Flock Safety, and Prepared 911. The explosion of digital evidence represents both a crisis and an opportunity, he noted, and Longeye’s focus on both AI speed and forensic-grade verification addresses the critical balance between utility and legal integrity.
The round also attracted support from Skydio’s founders, AI and security entrepreneurs, and law enforcement veterans, highlighting strong conviction across both the tech and public safety ecosystems. The funds will support product development, engineering expansion, deployment to more agencies, and a notable commitment: providing AI services free of charge to public defenders’ offices, signaling a broader dedication to balance across the justice system.
Longeye frames its technology as a way to dissolve long-standing trade-offs—between speed and thoroughness, between wide evidence collection and privacy, between closing cases and resource constraints. By enabling investigators to move “at the speed of crime,” the company positions itself not only as a law enforcement tool but as a force multiplier for the entire justice system.
