What Lexical Labs does
Lexical Labs is a UK-based legal technology company that builds Tiro, an AI-powered contract review platform designed to automate the review of inbound, third-party contracts for enterprise organizations. The company's primary customers are in-house legal and contract management teams, with additional use cases across sales and procurement teams, risk managers, and platform integrations that also target small business managers and freelancers. The platform addresses the high-volume, repetitive task of reviewing unfamiliar third-party paper against organizational policies and business rules, enabling triage, risk assessment, and accelerated turnaround.
Tiro combines deep-learning models, a logic-based expert system, and natural language processing to interpret contract concepts regardless of phrasing variations. The system performs automated review at contract intake, clause summarization, risk scoring across more than 20 dimensions, automated precedent search, and metadata extraction that can be pushed as structured data into downstream contract lifecycle management (CLM) systems. The platform is accessible through a web application, a Microsoft Word add-in, and APIs that connect to CLM and e-signature systems. Lexical Labs has layered optional GPT integration, most recently GPT-4 Turbo with a 125,000-token context window that handles documents up to 330 pages, and has introduced agentic AI capabilities for autonomous contract analysis, gap detection, and document retrieval within defined parameters.
The company generates revenue through SaaS subscriptions sold via an enterprise field sales motion with a consultative, demo-led buying process; pricing is not publicly disclosed. Lexical Labs operates as a group comprising Tiro Law Ltd (the primary trading entity) and Lexical Consulting Ltd, with its headquarters located in the Barclays Eagle Lab accelerator in Shoreditch, London. The company was founded in 2015 by Liam Gilchrist, with Simon Black serving as Chairman and William Becker as CTO, and operates with a team of 1-10 employees. Named enterprise customers include JERA & Co., Inc. (Energy) and Stantec Inc. (Engineering and Architecture).
