Legal technology startup Sandstone has raised $30 million in Series A funding to advance its artificial intelligence platform designed for in-house legal teams. The investment round was led by Lightspeed Partners, with participation from Sequoia Capital.

The funding comes as the legal technology sector continues to attract investor interest, particularly for companies developing AI-powered solutions. In-house legal departments at corporations have become a key target market for technology vendors seeking to automate routine legal tasks and improve efficiency.

Sandstone's platform aims to help corporate legal teams manage their workload more effectively through artificial intelligence tools. The company plans to use the funding to expand its product development and grow its customer base.

The investment reflects broader trends in the software industry, where artificial intelligence applications are driving renewed investor confidence after a period of reduced funding activity in the software-as-a-service sector. Legal technology represents one of several professional services areas where AI tools are being developed to assist with document review, contract analysis, and other routine tasks.
