Longeye Raises $20M Series A as More Than 50 Justice Agencies Adopt Its AI Investigative Platform

Funding led by N47, with participation from Andreessen Horowitz's American Dynamism practice, will expand Longeye across local, state, and federal justice agencies; Longeye expands Ambassador Team to help agencies transition to AI workflows

SAN FRANCISCO, October 21, 2026--Longeye, the leading AI-powered investigative workspace built for the justice system, has raised a $20 million Series A led by N47, with participation from Andreessen Horowitz's American Dynamism practice, and now has more than 50 justice agencies using the platform.

Those agencies have worked more than 2,300 investigations on Longeye, reviewing more than 15 million pages of documents, more than 10 million images, more than 32,000 hours of audio and video and more than a billion rows of financial and phone records. That represents more than 200,000 investigator-hours of evidence review, the equivalent of 100 investigators working full-time for a year. The casework includes at least 230 homicide investigations and at least 160 sexual violence cases.

Longeye works with local, state, and federal agencies across the U.S., and the funding will accelerate that growth.

Modern investigations generate more digital evidence than detectives can reasonably review by hand. In 2025, 14,085 people were murdered in the United States, 123,332 rapes were reported to police, and the FBI logged nearly $21 billion in internet crime losses, more than the City of Chicago's entire annual budget. Violent crime has fallen, but the evidence behind each case keeps growing: phones, message threads, bank records, video and jail calls, landing on teams already carrying full caseloads.

"Every investigation now produces evidence that could make the justice system more effective and more fair, and much of it goes unread because no one has the time to work through it," said T.J. Rylander, General Partner, N47. "When we spoke with agencies on the platform, investigators kept telling us Longeye was getting them through evidence that would otherwise have sat untouched, in a way they could check and defend. The Longeye team is taking a long-term, responsibility-first approach that stands out from the other companies in the space. We didn't see that anywhere else in the market."

Longeye lets investigators search and analyze evidence already collected in an investigation. While much of the market wraps general-purpose chatbots with little additional underlying infrastructure, Longeye pioneered the Faraday Method, an engineering system designed from day one around how criminal justice information has to be handled. Longeye has filed patents for its citation engine, which links every substantive finding to the original message, document, or recording, allowing investigators to verify the source before relying on it. Longeye meets the requirements of the FBI's CJIS Security Policy, and agencies retain ownership of their data.
