AI for the corporate legal team: practical, efficient, and investor-backed

Sandstone announced a $30 million Series A round led by Lightspeed Partners, with participation from Sequoia. The raise underscores growing investor confidence in AI companies that target enterprise workflows — in this case, bringing intelligent automation directly into in-house legal teams.

The startup’s platform applies machine learning to common legal tasks such as contract review, clause extraction, compliance checks, and playbook-driven approvals. By automating repetitive work and highlighting risk, Sandstone helps legal teams move faster, lower turnaround times, and focus senior lawyers on higher-value strategy and negotiations.

With the new capital, Sandstone plans to expand product features, deepen integrations with enterprise systems, and scale customer success and implementation teams to speed adoption. The backing from top-tier VCs like Lightspeed and Sequoia also gives customers greater confidence in Sandstone’s roadmap and long-term stability.

Why this matters:

  • In-house legal teams across industries can reduce backlog and operational costs while improving consistency and compliance.
  • Embedding AI into legal workflows democratizes access to legal insights, making smaller corporate teams more competitive.
  • Strong VC support accelerates industry trust and faster enterprise rollouts, bringing tangible benefits to more companies sooner.

Overall, Sandstone’s raise is a positive step for the legal tech market: it brings practical AI to a traditionally manual function, enabling faster decisions and more efficient corporate operations.
