Arceus raises $17M to build an AI-native law firm
What's the deal? ArceusDealroom has a profile for this one. Try Dealroom →, a startup pairing a law firm with contract-review software, raised a $17 million Series A led by Greycroft, with Craft Ventures and South Park Commons participating. The figure brings its total funding to $17 million. Founder Mac Liu says the firm can shrink a standard contract review from days or weeks to a few hours — and if it takes more than eight hours, it's free.
What's the endgame? Arceus staffs attorneys and builds software to speed their work. Employees submit contracts straight from Slack; a virtual agent pulls context from systems such as Salesforce and HubSpot, suggests changes, then routes the matter to one of the firm's lawyers for final review.
Who's building it? Liu, a two-time founder, isn't a lawyer. He held tech roles at Robinhood and Anduril, then started Vultron, which sold software to defense contractors. Earlier this year he sold Vultron to govtech firm pWin, keeping the cash and recycling it into Arceus.
Why it's different: Liu runs Arceus more like a startup than a firm. He hired engineers before his first lawyer, has employees in the office six days a week, and wants every customer request acknowledged within five minutes — a target he says the firm hasn't yet hit.
"You're not pinging a lawyer because you just want to chat," Liu said. "You're nervous about something, you're questioning something, and you want to feel like someone's there."
What could go wrong? Rival neofirms were often started by in-house lawyers whose software reflects years of legal work. Crosby founder Ryan Daniels was a fractional general counsel; Vector LegalDealroom has a profile for this one. Try Dealroom →'s Mitch Duncombe was a lawyer at Y Combinator. Liu lacks that firsthand legal background.
The signal: Arceus follows the model popularised by Crosby, recently valued at $400 million, which builds software for its own lawyers. Liu argues the real competition isn't other AI-native firms but traditional firms, in-house teams, and the software vendors selling to corporate lawyers. He expects customers may eventually need fewer internal lawyers — a lofty goal while most legal departments are still figuring out where AI belongs.
