Legora, the legal AI company valued at $5.6 billion earlier this year, said on July 29, 2026, that it is acquiring Wexler, a London startup whose software pulls verifiable facts out of very large sets of case documents. The price was not disclosed. Wexler was advised by TD Securities.
Wexler is Legora's fifth acquisition of 2026. Its product will become part of Legora's agentic operating system, the platform on which the company runs AI agents for legal work, and Wexler's engineers will form the founding team of a new Legora engineering hub in London.
Wexler's clients include litigation and disputes teams at law firms Clifford Chance, Goodwin and Herbert Smith Freehills Kramer, as well as legal and compliance teams inside large companies.
What Wexler built
Gregory Mostyn and Kush Madlani founded Wexler in January 2023 after meeting at Entrepreneur First. Mostyn, the chief executive, grew up around litigation through his father, a barrister who later became a judge, Artificial Lawyer reported. Madlani previously traded derivatives at JP Morgan, completed a master's degree in machine learning at UCL and worked on fraud-detection models at Tractable.
Rather than writing summaries of documents, Wexler's software passes them through a series of checks to isolate individual events: who said what, to whom, when, and why it matters to the case. Each fact can be traced back to its source, and the company says the system can work across more than one million documents in a single case. Lawyers use it to build chronologies and evidence records for litigation, arbitration and investigations.
In 2025 the company also launched Wexler Real-Time, a tool meant to flag false or inconsistent statements as they are made during depositions and hearings, Pulse 2.0 reported.
“Every dispute and every investigation comes down to the facts, and finding them is often the most manual and expensive part of legal work.”
Growth and funding
Wexler now has 18 staff and customers in both Europe and the United States. Legora said Wexler's revenue grew eightfold over the past year, with net revenue retention above 400%, meaning existing customers more than quadrupled their spending.
The startup raised a $1.4 million pre-seed round in December 2024 led by Myriad Venture Partners, with angel investors from ComplyAdvantage, Moonpig, Tractable and CreditKudos. In September 2025 it raised a $5.3 million seed round led by Pear VC, with Seedcamp, The LegalTech Fund and Myriad also taking part. At the time of the seed round it said more than 70% of its users were in the US.
Why Legora is buying
Legora chief executive Max Junestrand said that disputes and investigations depend on establishing the facts, which is often the slowest and most costly part of legal work. He argued that as AI agents take on more of that work, the number of fact queries will rise sharply, and that Wexler's system is built to handle that volume.
Inside Legora, Wexler's engine will act as the fact layer under the company's agent workflows. Litigators will be able to assemble chronologies and evidence records without leaving a matter workspace, while in-house teams will be able to search contract and communication archives for factual risks before they become claims.
Mostyn said building the factual picture of a case is the hardest part of disputes work, and that Wexler would keep serving both litigators and in-house teams after joining Legora.
Legora's acquisition run
The deal follows a $600 million Series D earlier in 2026 that valued Legora at $5.6 billion. The company says more than 100,000 lawyers at 1,500 law firms and in-house legal teams in over 50 markets use its platform.
Wexler follows Walter AI, Qura, Graceview and Cadastral, the four companies Legora had already bought in 2026, according to Legal Technology and Lawyers Weekly. With five acquisitions in seven months, Legora has been using its new capital to add specialist products and teams, and Wexler's staff give it an engineering base in London.
