Legal Assist AI Reviews

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 lead orchestrator behind every Leah product. It 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. Irreversible actions wait for human approval, and company playbooks and precedent are engineered into each agent's context. Leah Contracting, Leah Legal, Leah Procurement, and Leah Finance all run on Maestro, so work moves across functions without manual coordination. A contract negotiated in Leah Contracting can carry its obligations into procurement and surface its exposure into legal. Each new workload runs on the same harness, with the same governance and audit trail. Leah prices against completed workloads, so customers pay for work, not tokens. Customer data is never used to train models, and the agents, workflows, and applications customers build remain their intellectual property. Leah is SOC 2 Type II certified and runs single tenant on any cloud, in any region, or on a virtual machine inside the customer's own perimeter. Leah has offices across New York, London, Dubai, Mumbai, Sydney, Glasgow and Singapore.
