Description

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.
