Legora today (29 July) announced that it is acquiring London-based startup Wexler, which uses large language models to help lawyers extract and organise key data from documents relevant to their case. Wexler is used by some of the world’s leading litigation and disputes teams at Clifford Chance, Goodwin, and Herbert Smith Freehills Kramer, as well as in-house legal and compliance teams at large global enterprises. Its engineering team will form the founding team of Legora’s London engineering hub. This is Legora’s fifth acquisition in 2026.
“Every dispute and every investigation comes down to the facts, and finding them is often the most manual and expensive part of legal work” said Max Junestrand, CEO and co-founder of Legora. “As agentic systems take on more of that work, fact queries won’t just grow, they’ll multiply by orders of magnitude. Wexler is the infrastructure built to handle that scale today.”
Wexler’s engine runs documents through a gated pipeline that isolates discrete, verifiable happenings – who said what, to whom, when, and why it matters to the case – rather than returning summaries or loosely sourced excerpts, at scale over 1,000,000 documents per case. The product is used by litigators, arbitrators and investigators working matters that require exhaustive, source-traceable fact development, the fact-lawyering at the heart of every dispute, as well as in-house legal teams to surface and resolve factual issues before they escalate into disputes.
Wexler was founded in January 2023 by Gregory Mostyn and Kush Madlani. The company has since grown to a team of 18 with a significant client base in Europe and the United States, expanding revenue eightfold year-on-year with over 400% net revenue retention. Wexler’s product will become part of the Legora agentic operating system, and their team will become a cornerstone of the engineering hub Legora is building in London.
“Fact-lawyering is the most challenging part of disputes work: the endless, painstaking review needed to map the facts, the issues and the characters into a compelling theory of the case,” said Mostyn. “From a week-long investigation to a decade-long class action, building the case brain has never been harder, and it has never mattered more. We are delighted to be joining Legora and to continue serving the expert litigators and investigators working on the world’s most complex cases, as well as the in-house teams trying to get ahead of those cases before they’re ever filed.”
We’re told that combined with Legora’s platform, Wexler’s engine will become the fact layer underneath Legora’s agentic workflows. Litigation teams working inside Legora will be able to build the case brain for every matter: fact chronologies and evidentiary records without leaving a matter workspace, corporate legal teams will be able to use it across contract and communication archives to catch factual exposure before it becomes a claim.
The acquisition follows a $600 million Series D round earlier this year that valued Legora at $5.6 billion. Legora’s other acquisitions this year are Walter AI, Qura, Graceview and Cadastral.
