Sandstone: release blog. When you work in legal for long enough, you start to see a pattern: the smarter and faster the business moves, the more legal becomes the bottleneck. It's not because legal teams aren't strategic. It's because their context, the playbooks, instincts, and judgment that make them indispensable, gets lost between inboxes, Slack threads, and SharePoint folders. That's the problem Sandstone built Sandstone to solve. Today, Sandstone is officially launching Sandstone and announcing its $10M 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. See more on its incredible advisory panel here. Sandstone built Sandstone for every in-house lawyer who's ever thought: There has to be a better way to work. From frustration to focus. My co-founder Jarryd lived it firsthand as in-house counsel at a fast-growing B2B software company. Every day, he was buried under Slack pings, procurement tickets, and redlines. Each one depending on some bit of institutional knowledge hidden in someone's head or an outdated doc. Meanwhile, I spent years at McKinsey leading the legal tech practice, building legal tech for big firms and Fortune 100 companies. A lack of context impacted every layer of every company I worked with. When Jarryd and I compared notes, the realization was simple but profound: in-house legal teams actually want transformation. There has not been an AI tool built to serve their needs. Sandstone brought together a remarkable team of lawyers and engineers from across legal tech and AI research, and Sandstone was born. What Sandstone has built. Sandstone is the first platform for AI-native legal departments. It unifies legal data, workflows, and business context into a single intelligent system embedded directly within the tools businesses already use. Instead of reinventing the wheel with every intake or contract, Sandstone helps legal teams retain and evolve their know-how by creating a legal home that becomes their secret weapon. Its vision is that in-house legal teams wake-up in the morning and check Sandstone. It is not just another point solution they use at work, it is the way they work. Sandstone turns lawyers into 10x legal-business strategists, and enables the legal team to be a revenue center, not a cost center... And it happens in a beautiful, intuitive interface. For the people who make it real. This launch belongs to the team as much as the vision. The builders, engineers, and legal ops pros who've put their fingerprints on every line of code: you've turned an idea into a living platform. To its early clients: thank you for your belief and your feedback. You've helped Sandstone shape Sandstone into something real and practical, not theoretical. To its investors and advisors: thank you for seeing the potential in what's long been an overlooked category. Your guidance, from AI research to enterprise scaling to legal innovation, keeps Sandstone honest and ambitious. And to everyone in-house who's ever said, "We need something designed for us," this is for you. Sandstone is just getting started, and Sandstone is already working with dozens of in-house teams from fast-growth startups to global enterprises. Sandstone has assembled a super-team of legal engineers. Its team brings experience from places like McKinsey, Microsoft, Google, Davis Polk, LexCheck, NetDocuments, Paul Hastings, Luminance, Robin AI, Akin Gump, Brightflag, Wolters Kluwer, and many other leading firms and tech companies. Sandstone has former GCs coding and working directly with its clients. If you're an in-house lawyer, legal ops leader, or GC who's ready to work differently, join Sandstone. - Nick and the entire Sandstone Team
