Sandstone is an AI-native platform built for corporate legal departments — the lawyers working inside companies, not law firms. It acts as an operating layer that unifies all incoming legal work arriving through Slack, email, and Jira, triages it automatically, then executes tasks like contract drafting, redlining, and legal analysis using AI workflows trained on each company's own institutional knowledge (prior contracts, playbooks, past decisions). Crucially, it also pulls in business context from HR, sales, and other internal systems, so lawyers see counterparty history and strategic signals before they start work. The product tracks legal ops metrics like cycle times and auto-resolution rates so GCs can report measurable value to the C-suite. It is sold to General Counsel, CLOs, legal ops leaders, and practice area leads at both SMBs and Fortune 500s. The key differentiation: Sandstone is built for the operational chaos of in-house teams, not the legal reasoning needs of private practice — a segment the founders argue has been systematically underserved by the AI legal boom.
