Corporate legal departments have long been slower to adopt new technology than their outside counsel counterparts. A $30 million Series A funding round for Sandstone suggests that gap is closing quickly.
The round was led by Lightspeed Partners with participation from Sequoia Capital. Sandstone plans to use the capital to expand its AI platform designed specifically for in-house legal teams. The company targets the repetitive, document-heavy work that bogs down corporate lawyers: contract review, compliance checks, and nondisclosure agreements.
AI Targets a New Legal Frontier
Most legal technology investments have focused on law firms. Sandstone takes a different approach by building for corporate legal departments directly. These teams often manage thousands of contracts with small staffs, making them prime candidates for automation.
Generative AI models now allow these tools to extract key terms, flag risks, and even suggest edits. Sandstone's system learns from each organization's own legal playbook. This reduces the manual review time from hours to minutes.
Why This Matters
In-house legal teams face mounting pressure to control costs while handling more work. The average corporate legal department spends over 60% of its budget on outside counsel. By automating routine tasks, Sandstone helps bring that work back inside.
The practical impact is significant. Legal operations leaders can reallocate their lawyers to higher-value strategy work rather than contract reading. For businesses, faster contract cycles mean faster deals. The investment from Lightspeed and Sequoia signals that venture capital sees this as a multi-billion dollar opportunity.
Funding Signals a Shift in Legal Tech
Sandstone joins a growing list of startups competing in the legal AI space. But its focus on in-house teams rather than large law firms gives it a distinct position. The Series A round suggests investors believe the corporate legal market is ready for enterprise-grade AI.
The company will face challenges. Data privacy is paramount when dealing with sensitive legal documents. Sandstone must also prove its tool integrates smoothly with existing document management systems. Still, the funding provides a strong runway to address these issues.
As AI continues to reshape professional services, Sandstone's raise is a clear indicator that corporate legal work will not be left behind.
