As answered by people managing Leah and LayerStack Arm-based Cloud Server.
Leah's answer
A Harness, Not a Copilot: An agent can do a task. A harness gets agents working together to run the process reliably. Deterministic handoffs, approval gates, context engineering, observability, and a full audit trail.
Depth Beats Breadth: Built for the commercial enterprise with a decade of operational depth inside Fortune 500 legal, contracting, and procurement operations. Domain-specialized agents handle the regulatory, contractual, and procurement realities that horizontal AI cannot.
One Connected System: A contract negotiated in Contracting carries its obligations into procurement and surfaces exposure into legal. One harness, not three silos passing files.
Pay for Work, Not Tokens: Leah prices against completed workloads, aligning cost to work done.
Run It Where You Want: Single tenant on any cloud, any region, or on a VM inside the customer's perimeter.
Build It, Own It: Customer data never trains models. Agents, workflows, and applications customers build remain their IP.
