New York-based startup Manifest OS has closed a $60 million Series A round at a $750 million valuation, with backing from Menlo Ventures, Kleiner Perkins, First Round Capital, and Quiet Capital. The company has been set up to power new model law firms using fixed-fee and outcomes-based pricing. It is positioning the raise as the largest Series A in legal technology history – unless we’re missing something it’s not, Eudia raised $105m Series A last year, but it’s a massive Series A nonetheless, particularly as it has been in stealth mode to date. [NB A representative for Manifest OS has contacted us to point out that Eudia received $30m in commitments upfront with a remaining $75m contingent upon them acquiring other companies and that therefore this is the biggest.]
Manifest OS intends to build and operate its own law firms under the “Manifest Law” brand, currently focused on business immigration. The model combines a proprietary AI platform, centralised back-office operations, and a shared brand.
The company launched its first firm 18 months ago under Arizona’s alternative business structure (ABS) programme.
Founder and CEO Dan Mishin, himself a former immigrant entrepreneur, frames the core problem as the billable hour model, which he argues creates misaligned incentives for both clients and lawyers. He points to data suggesting 80% of American businesses and consumers cannot afford legal help when they need it, and notes that billing rates rose an average of 7.4% in 2025.
Michael Bloch, a partner at Quiet Capital, said in a post today (28 April): “When I first met Dan Mishin, most legal AI companies were building copilots and thin model wrappers for lawyers. AI-native services were still deeply non-consensus. Dan and I aligned immediately on the real opportunity in legal: not giving lawyers one more tool, but using AI to provide and power better legal services directly.”
Manifest says it plans to use the funding to expand into global immigration services.
