But while those tools focus on private practice, some startups believe there’s still plenty of the legal market that isn’t being served. Sandstone, which announced $30 million in Series A funding on Tuesday, is focused on an overlooked slice of the legal space, focusing on the tangle of overlapping tasks and systems facing in-house legal teams.

The Series A was led by Lightspeed Venture Partners, with participation from existing investors at Mantis VC, SV Angel, Operator Partners, Kearny Jackson, Daybreak Ventures, Litquidity Ventures, and others. The Series A comes just six months after a $10 million seed round in January, which was led by Sequoia. As the founders describe it, Sandstone’s initial user base will be the legal departments at small and mid-sized businesses.

Instead, Sandstone focuses on relationship management and workflow automation, both tuned to the unique demands of in-house legal work. As Strydom sees it, the focus on in-house legal departments allows Sandstone to provide value where more generalized AI deployments often flounder. Anthropic has been steadily expanding its Claude for Legal offering, adding new tools in May for case law searches and deposition prep.
