Sandstone Raises $30M for the Legal Work Nobody Wants to Do
Sandstone just closed a $30M Series A led by Lightspeed, six months after a $10M seed from Sequoia. That cadence, two top-tier firms, two rounds, half a year apart, tells you the in-house legal agent space got hot fast.
What Sandstone goes after is deliberately unglamorous: the tangle of overlapping tasks and systems that in-house legal teams drown in. Not the flashy AI lawyer arguing in court demo, but the grind of contract intake, routing, and tracking obligations across systems that don't talk to each other. It's a vertical where the work is structured, the documents are dense, and the people doing it are expensive, which is exactly the shape of problem agents are good at and buyers will pay for.
The funding pattern is the real signal. Sequoia seeds it in January, Lightspeed leads the A in June. When two firms that usually compete both want in within six months, it means the early revenue is real and the category is being raced for. Legal has already produced Legora at a $5.55B valuation and Harvey before it. Sandstone is betting the in-house seat, not the law firm, is the next land grab.
Worth watching whether agents for in-house legal becomes its own category or gets absorbed by the horizontal coding and knowledge agents. For now, the money says it's a category. Link: https://techcrunch.com/2026/06/09/sandstone-raises-30m-to-bring-ai-to-in-house-legal-teams/
