Sandstone raises $30M to bring AI to in-house legal teams

Overview

Sandstone, a startup building AI tools for corporate legal departments, has raised a $30 million Series A led by Lightspeed Venture Partners. The round arrived six months after a $10 million seed led by Sequoia, bringing total funding to $40 million in under a year. The company says revenue grew more than 40x over the prior 90 days as it signed customers including Wayfair, Grindr, and ElevenLabs.

Key Takeaways

  • Sandstone's Series A comes just six months after a Sequoia-led seed round.

    With Harvey and Legora burning through eight-figure funding rounds, legal tools have proven to be one of the fastest-growing and most hotly contested verticals among AI startups.

  • 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.

  • The result has little in common with legal reasoning systems like Harvey and Legora.

    Instead, Sandstone focuses on relationship management and workflow automation, both tuned to the unique demands of in-house legal work.

  • Sandstone will also face heated competition from frontier AI labs, which are increasingly turning their attention to the legal space.

    Anthropic has been steadily expanding its Claude for Legal offering, adding new tools in May for case law searches and deposition prep.

  • Through candid fireside chats and high-impact networking, you'll walk away with valuable insights and new connections.

With Harvey and Legora burning through eight-figure funding rounds, legal tools have proven to be one of the fastest-growing and most hotly contested verticals among AI startups. But while those tools focus on private practice, some startups believe there's still plenty of the legal market that isn't being served.

As the founders describe it, Sandstone's initial user base will be the legal departments at small and mid-sized businesses. "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," co-founder and chief operating officer Jarryd Strydom told TechCrunch. "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."
