LONDON, Sept. 23, 2025 – wexler.ai, the AI platform for complex litigation, today announced a $5.3 million seed round led by Pear VC, with participation from Seedcamp, The LegalTech Fund, and pre-seed lead investors Myriad Venture Partners. The funding comes as the company launches Wexler Real-Time, a groundbreaking real-time legal fact-checking feature as part of its fact intelligence platform, already used by top global firms to build chronologies, query vast case materials, and surface key inconsistencies. The new capability flags false or inconsistent testimony as it’s spoken in depositions and hearings. The company also announced new global law firm customers including HSF Kramer, Goodwin Procter, and Addleshaw Goddard.
Since its pre-seed round in 2024, wexler.ai has grown its ARR by 20x and reduced manual review by at least 75%, helping leading law firms and corporate legal teams establish facts faster and with greater accuracy. Long-standing customer Clifford Chance has also embedded wexler.ai across its dispute resolution practice, and Burges Salmon has also adopted the platform to enhance its legal workflows.
“We’re replacing slow, manual, and error-prone litigation review with a system that thinks like a litigator but operates at machine scale and speed,” said Gregory Mostyn, co-founder and CEO of wexler.ai. “With our newest release, litigators can not only build a winning case strategy by mastering the evidence, but challenge inaccuracies as they happen in proceedings.”
“At Pear, we love to partner with highly ambitious founders who are tackling big problems with unique tech," said Kathleen Estreich, Partner at Pear VC. “Greg and the wexler.ai team are building what’s quickly becoming essential infrastructure for litigation. They combine real-time fact-checking with workflows designed for how lawyers actually win cases, becoming essential for all litigators.”
“In complex disputes, establishing the facts is often challenging and time consuming,” said Charlie Morgan, Partner at HSF Kramer. “The wexler.ai platform is helping our teams do this more quickly and effectively, which in turn helps us improve case strategies, deliver more value and secure the best outcomes for our clients.”
Purpose-Built AI for Litigation
Unlike broad legal AI tools, wexler.ai is designed specifically to think like a litigator. The platform delivers verified, actionable facts with speed and scale, replacing slow and error-prone factual analysis with workflows built for case strategy. For example, tasks like building detailed chronologies that once took days can now be completed in about an hour.
“Litigation is one of the most complex and high-stakes areas of law, and wexler.ai is redefining how lawyers uncover and use facts,” said Tom Wilson, Partner at Seedcamp. “We believe Wexler’s team is building foundational technology that will change the economics of litigation, making legal teams faster, sharper, and ultimately more successful.”
The system extracts, analyzes, and verifies key factual information across massive case datasets, transforming raw data into usable work product. With the ability to process up to 500,000 documents per upload and support multilingual deployments, the technology enables global firms to handle the complexity of modern disputes with precision.
BigLaw Adoption & Multinational Expansion
Growing adoption across top-tier firms highlights the platform’s category-defining role in litigation. From AmLaw 50 leaders in the U.S. to multinational firms in London, and rapid growth in APAC, users report dramatic reductions in review time and stronger confidence in case strategy. Today, more than 70% of wexler.ai users are in the U.S., with rapid growth across the UK, Europe, Canada, and Australia.
“We like the accuracy and litigation-focused design of Wexler - it's truly a product for litigators.” said David Hobbie, Director, Knowledge & Innovation at Goodwin. “Our lawyers have found it invaluable for early case assessment and thorough fact analysis, including identifying conflicting evidence. We look forward to continuing our partnership with Wexler as adoption spreads and as more fact-related features like the real-time fact checking function are released.”
The new funding will accelerate wexler.ai’s product development; increase the scale of documents to millions per upload, expand the engineering and commercial teams; support wexler.ai’s U.S. launch; and scale multilingual, region‑specific deployments to meet growing demand from top‑tier law firms and corporate teams. Built by privacy and security experts, wexler.ai employs user-specific encryption keys, data masking, and complies with SOC 2 Type II, ISO 27001, GDPR, and AWS Cloud Security standards.
