Sandstone Announces its Launch to Invent a Better Way for In-House Lawyers to Work

Sandstone, the home for AI-native legal departments, led by Nick Fleisher, Liam Germain, and Jarryd Strydom, has announced its launch with a $10 million seed round led by Sequoia, with participation from an incredible group of additional investors as well as over 20 GCs, law firm partners, and customers.

Experience in fast-growing B2B companies and legal tech consulting revealed a critical gap: in-house legal teams face inefficiencies from scattered knowledge and outdated processes, with no AI tools built for their needs. Sandstone was founded by a team of legal and AI experts to transform in-house legal operations.

Sandstone is the first AI-native platform for legal departments, unifying legal data, workflows, and business context into a single intelligent system within existing business tools. This “context in motion” allows legal teams to retain and evolve knowledge without reinventing processes for each contract or intake.

Designed as a central hub rather than a point solution, Sandstone transforms legal operations, enabling teams to act as strategic business partners and revenue generators, all through an intuitive, user-friendly interface.

The launch reflects the work of engineers, legal ops experts, and builders who turned Sandstone into a living platform. Early clients shaped it with feedback, while investors and advisors contributed guidance spanning AI research, enterprise scaling, and legal innovation.

Sandstone’s mission is to enable the first generation of AI-native legal departments, where institutional knowledge becomes a core competitive advantage. Already deployed across dozens of in-house teams from fast-growth startups to global enterprises, the platform is supported by a team of legal engineers with experience at McKinsey, Microsoft, Google, Davis Polk, LexCheck, NetDocuments, Paul Hastings, Luminance, Robin AI, Akin Gump, Brightflag, Wolters Kluwer, and other leading firms. Former GCs work directly with clients to ensure practical, scalable solutions.
