Leah is an enterprise agentic AI company designed to autonomously run complex work across legal, procurement, finance and shared services. Founded in London in 2015 and backed by SoftBank and Insight Partners, Leah serves 400+ global enterprises and supports mission-critical processes in regulated industries. Leah works with partners including Microsoft, Google, OpenAI, Anthropic, PwC and KPMG to support enterprise transformation programs globally. Leah Maestro is the agentic operating system behind every Leah product. It’s the harness that governs how specialist agents act through deterministic handoffs, approval gates, context engineering, memory, permissions, and observability, with an auditable record at each stage. Enterprises decide where autonomy ends and human authority begins. Leah Contracting agents apply company playbooks, draft and redline agreements from pre-built industry templates, and run market-standard and playbook-based risk review. They negotiate with clause-level autonomy and keep obligations running within governance. Leah Legal coordinates specialist sub-orchestrators, from contract review, obligation tracking and matter management to privacy, IP, and outside counsel spend, with legal teams holding approval authority at every gate. Leah Procurement runs source-to-pay from requisition to payment and supplier intake to contract close. Agents act across spend orchestration, sourcing, negotiation, contract management, and supplier risk monitoring. Leah Finance applies the same governed execution to revenue recognition and financial controls, giving finance teams agent-driven speed with the approval gates and audit trail Maestro provides. Leah has offices across New York, London, Dubai, Mumbai, Sydney, Glasgow and Singapore.

Claude for Legal is an AI-powered assistant developed by Anthropic designed specifically for legal professionals, enabling them to efficiently manage documents and conduct research. This tool is capable of summarizing extensive files, extracting and comparing crucial information, drafting and refining text, and aiding in the analysis of contracts and various documents. Legal teams, whether in law firms or corporate settings, can leverage Claude for Legal to streamline their document workflows and access recurring knowledge, ensuring they have the necessary context and source materials at their fingertips. Additionally, users can review the AI-generated responses as part of their comprehensive workflow. Available on both desktop and mobile platforms, Claude for Legal facilitates information processing and content creation; however, it is essential for users to verify the outputs, exercise professional judgment, and make informed legal decisions independently as part of their practice. This means that while the AI can enhance efficiency, the ultimate responsibility for legal accuracy and compliance remains with the user.
