Sandstone Launches with 10 Million Dollar Seed Led by Sequoia for AI Legal Teams

New York based startup Sandstone has officially launched with 10 million dollars in seed funding led by Sequoia Capital to address the persistent inefficiencies in corporate legal departments. The investment round included participation from SV Angel, Kearny Jackson, and over 20 general counsels from major corporations. The platform is designed to turn fragmented institutional knowledge into live, agentic workflows that integrate directly with business tools like Slack and Salesforce.

The company was founded by legal and technology veterans from firms such as McKinsey, Davis Polk, and NetDocuments who were frustrated by the administrative tax of repetitive work. Co-founders Nick Fleisher and Jarryd Strydom recognized that legal teams were often buried in procurement tickets and redlines due to a lack of shared context. Their solution acts as a Legal Home where teams can operationalize their expertise rather than just storing documents.

Sandstone allows legal departments to deploy custom AI agents in under ten minutes to handle intake and triage. These agents learn from every interaction to build dynamic playbooks that evolve with the company's risk profile. By connecting every workflow to the specific business context, the platform ensures that legal intelligence is applied consistently across the entire organization.

The startup is already partnering with dozens of in-house teams ranging from fast growing startups to Fortune 500 companies. Early customers report a dramatic reduction in turnaround times and better visibility into operational bottlenecks. As the legal industry moves toward AI native solutions, Sandstone positions itself as a critical layer for business orchestration.

According to Sequoia partner Bogomil Balkansky, the founders' unique blend of in-house experience and technical scale is what sets the platform apart. The new funding will support the growth of the engineering team and the expansion of the platform's capabilities.
