Sandstone Raises $30M to Modernize In-House Legal Teams

Sandstone has raised $30 million in Series A funding, led by Lightspeed Venture Partners, to build AI-powered tools that give in-house legal teams a shared, searchable layer of institutional knowledge.

In-house legal teams have long relied on individual lawyers to retain and apply institutional knowledge. Sandstone says this creates a core problem: when legal context lives only in people's heads, it cannot scale, cannot be routed intelligently, and is lost when those people leave. The company's software is designed to capture and centralize that context so it can be used across every legal workflow.

The Funding Round

Sandstone closed a $30 million Series A round led by Lightspeed Venture Partners. Existing investors also participated. The company previously closed a seed round, though the amount was not disclosed publicly.

The funding will go toward scaling enterprise customer success, hiring across all functions, and building a community for in-house legal professionals.
