Sandstone raises $30M for AI built around in-house legal work

Sandstone has raised $30 million to expand an AI platform designed for in-house legal teams. The company is targeting the work that sits between legal advice and business operations, where corporate counsel must review contracts, answer recurring questions, manage approvals, and coordinate with teams across a company. That focus distinguishes the product from general-purpose legal chatbots and consumer-facing document tools. The financing adds to a crowded but commercially important legal-AI market in which buyers care as much about permissions, audit trails, and integration with existing systems as they do about model quality. Sandstone's test will be whether it can become a system of action for legal departments rather than another drafting assistant, and whether its automation produces measurable reductions in outside counsel spending or turnaround time.
