Inside Peregrine's cold case agent: 300GB of evidence in an hour

Key takeaways from the Sequoia Capital interview with Peregrine co-founder Ben RudolphDealroom has a profile for this one. Try Dealroom → (September 2026):

A cold case agent as the first product. Rudolph said Peregrine's very first agent tackled cold cases — investigations where a detective must manually sift through 200-300 gigabytes of video, audio, images and PDFs, often still stored as paper records.

Reproducing an exoneration. The agent was built with a customer who had once wrongly convicted and later exonerated a man; asked whether an agent could reproduce that result, Peregrine fed it all the case evidence and, after 30-60 minute runs, matched the detectives' original findings.

Placing a suspect in a Wisconsin case. Now deployed in several US departments, the agent recently worked a similar 300GB case in a Wisconsin county, helping place a suspect at both the crime scene and where the body was found using scattered cell call-detail records.

Unburdening public servants. Rudolph framed the technology as a way to relieve detectives from watching and listening to hours of administrative video and audio, letting agents surface the insights buried in vast, disparate datasets.

Operational outcomes over dashboards. He described Peregrine's agents in terms of concrete outcomes for end users — running for extended periods to glean insights human investigators would take far longer to reach.
