Gregory Mostyn

Gregory Mostyn is the CEO and Co-Founder of Wexler, a fact intelligence platform designed to extract, analyse, and verify facts from complex, unstructured information. The primary focus of the system is complex resolution in legal disputes, but it is used across investigations, tax, forensics and insurance claims handling. The platform extracts events, entities, timelines and contradictions from evidence and links each fact to its source sentence, identifying inconsistencies, building the cast of characters and powering complex queries over 250K+ document sets. It is already in use by major law firms, including Clifford Chance, Goodwin Procter, Addleshaw Goddard, and HSF Kramer. Prior to Wexler, he led content, marketing, and sales teams across two senior leadership roles, building go-to-market expertise and an extensive network within the legal sector.
