TrialMatrix started in a courtroom.

Founded by trial lawyers from Kirkland & Ellis and Cooley. Built by an engineer who ran systems at Amazon and Meta.

The case record outgrew memory.

A single matter now produces millions of emails, messages, and exhibits. A handful of lines in mountains of evidence can decide the case. For decades we found them the only way there was: war rooms, chronologies, and the memory of whoever had lived with the case longest, usually a fourth-year associate at 2 a.m. That worked before. It does not work at this volume.
The contradiction that breaks an expert could be sitting in an interrogatory response from ten months back. Maybe someone remembers it at exactly the right time. What if no one does?
TrialMatrix builds a structured ontology of every assertion in your case — who said it, when, under oath or not, and what it contradicts elsewhere in the record. Every answer cites the exact line of evidence it came from.
Built by trial lawyers. Command of the record should be engineered, not remembered.

Courtroom judgment meets hyperscale systems.

The new way to build a case

It was night and day from one trial to another. In our last multi-week MDL, TrialMatrix was the single source of truth. Every contradiction in their expert's deposition was flagged instantly.
Diana Hu
Litigation Partner, Cooley LLP
The most useful litigation tool I currently pay for, hands down. It's fast, connects exhibits directly to witness outlines, and handles complex discovery without slowing down.
Max Harrison
Trial Counsel, Latham & Watkins
The best trial prep platforms have a deep connections engine. TrialMatrix doesn't just store documents; it maps the relationships between facts and witnesses so nothing gets lost.
Andrej Karpathy
Founder, Blackwell Legal
We went from hundreds of loose PDFs to a fully connected matrix of facts. We spend less time searching and more time crafting the narrative. Truly an unfair advantage in the courtroom.
Patrick Collison
Managing Partner, Crawford & Co.
No more frantically searching binders mid-trial. I called out a contradiction in written discovery from ten months ago, locked to the citation. The jury saw it instantly.
Yuri Favi
Senior Associate, Finnegan
It's definitely becoming a requirement for modern litigation. It raises the baseline of what's possible in complex business trials. Simply brilliant engineering.
