For the makers and artists of the legal landscape—specifically the legal departments at small and mid-sized businesses—this funding round signals a shift away from the high-stakes private practice tools dominating the headlines. While the industry watches giants like Harvey and Legora consume eight-figure rounds, a new contender is targeting the overlooked reality of in-house teams drowning in overlapping tasks and fragmented systems. Sandstone has raised $30 million in Series A funding to solve exactly that mess.
The funding round and key backers
The Series A was led by Lightspeed Venture Partners, joining existing investors Sequoia, Mantis VC, SV Angel, Operator Partners, Kearny Jackson, Daybreak Ventures, and Litquidity Ventures. This injection comes just six months after a $10 million seed round in January, which was also fronted by Sequoia.
Why in-house legal teams matter
Unlike the legal reasoning engines built for private practice, Sandstone focuses on relationship management and workflow automation tailored to the unique demands of internal legal work. As co-founder and chief operating officer Jarryd Strydom explained to TechCrunch:
“They open up their laptop in the morning, they see all the work that’s come in through different intake channels, whether that’s Slack messages, emails, Jira. AI helps them route and triage that work appropriately, and then they can build custom workflows on top of our platform to actually execute work, whether that’s drafting, reviewing, or providing legal analysis.”
The strategy is to provide value where more generalized AI deployments often fail. Strydom notes that Lightspeed’s conviction lies in highly specialized vertical AI, arguing that a granular understanding of workflows is essential to determine how artificial intelligence can genuinely assist.
Competing with the giants
Sandstone will inevitably face stiff competition from frontier AI labs increasingly turning their gaze toward the legal sector. Anthropic has been steadily expanding its Claude for Legal offering, having added new tools in May specifically for case law searches and deposition prep.
