Manifest OS raises $60m to build AI-native law firms outside billable hour model
Manifest OS, an AI legal technology startup, has raised $60 million in Series A funding at a $750 million valuation. Menlo Ventures, Kleiner Perkins, First Round Capital and Quiet Capital led the round.
The company builds and supports law firms that operate on outcomes-based pricing rather than billable hours. It uses AI to automate research, data handling and drafting tasks.
Dan Mishin, Manifest OS founder and CEO, said the funding enables the company to "rethink the entire business model of a law firm." He explained the deliberate choice not to sell software to existing firms, which have financial incentives to bill more hours.
"Instead, we partner with forward-thinking lawyers to help them become market leaders in their respective practice areas, with AI at their core from day zero," Mishin said.
How the model works
Manifest OS operates law firms under the Manifest Law brand. The company incubated its first firm in business immigration through Arizona's Alternative Business Structure program.
Each firm combines three components: a unified brand, an end-to-end AI platform and a centralized back office.
Ilya Fushman, managing partner at Kleiner Perkins, said the approach differs from typical legal tech sales. "Selling AI-native services is where a lot of the industry's value will be concentrated, and Manifest OS is uniquely positioned to build a category-defining market leader," he said.
Background
Mishin founded Manifest OS two years ago. The company operates offices in New York, San Francisco and Phoenix.
Before starting Manifest OS, Mishin founded technology-focused property company June Homes and co-founded real estate investment firm NextStory Capital in New York, exiting both last year.
