Sandstone - 2026 Pricing, Features, Reviews & Alternatives

Sandstone is a cloud-based AI-native operating system for in-house corporate legal departments, designed for General Counsel, CLOs, associate and assistant GCs, practice area leads, and legal operations professionals at scaling companies and enterprises. The platform unifies legal relationships, documents, companies, people, and past decisions in a single connected repository, replacing fragmented inboxes and disconnected tools with a structured, centralized source of record. Sandstone layers across an organization's existing tech stack through 50+ integrations, including email, Slack, and document hubs, without requiring workflow changes from the broader business.

At the core of Sandstone's functionality are AI agents that handle intake, classification, risk scoring, and routing of legal requests drawn from existing business systems. Agents interpret intent, gather context, and direct work to the attorney with the appropriate expertise and available capacity. Routine matters, such as NDAs backed by approved templates, can be auto-resolved with escalation logic applied to higher-risk items. Playbooks are built from existing templates, redlines, and policies, and refine with each use to keep legal positions consistent across the organization. This policy-backed triage model reduces time spent on manual categorization and allows legal teams to maintain defensible, repeatable positions at scale.

Sandstone is built to shift attorney time away from routine triage toward higher-judgment work, positioning in-house legal as a proactive business function. The agentic matter management layer connects intake directly to resolution, with full context preserved throughout each workflow. By consolidating legal data, automating first-pass responses, and integrating with the tools teams already use, Sandstone gives legal operations professionals and practice area leads the infrastructure to manage growing request volume without proportional headcount increases.
