Side-by-side comparison of AI visibility scores, market position, and capabilities
AI-native workflow platform for in-house legal teams raised $10M seed led by Sequoia Capital; 20+ customers including Fortune 500;
About
Sandstone is an AI-native workflow platform built specifically for in-house legal teams, founded in 2023 in San Francisco. The company was created to address a structural problem in corporate legal departments: the volume of routine legal work has grown faster than headcount budgets, leaving general counsels and their teams buried in repetitive contract review, policy analysis, and cross-functional requests. Sandstone's platform automates and streamlines these workflows without requiring the legal team to become technologists.\n\nSandstone's core product allows in-house teams to build AI-powered workflows for contract review, legal intake routing, policy Q&A, and compliance tracking — all configurable without engineering support. The system integrates with existing document management platforms and communication tools, fitting into how legal teams already work rather than requiring a rip-and-replace approach. Target customers are general counsels and legal operations leaders at Fortune 500 and mid-market companies with in-house legal teams of five or more attorneys.\n\nSandstone raised a $10 million seed round led by Sequoia Capital and has signed more than 20 Fortune 500 customers since its 2023 founding — a rapid enterprise adoption curve that reflects both the quality of its product and the credibility of its Sequoia backing. The company operates in the emerging AI legal tech sector alongside tools like Harvey and Ironclad, but its focus on workflow automation for in-house operations teams rather than legal research or CLM gives it a differentiated position in a large and underserved market.
Relativity confidentially filed for IPO in early 2026, the first legal tech company to do so since 2021, while rebranding as a legal data intelligence platform.
