AI law startup Norm said on Tuesday it had raised $120 million in a Series C funding round led by Khosla Ventures, valuing the nearly three-year-old startup at $1.2 billion.

Norm has created an AI-native law firm, called Norm Law, that uses the company’s own AI agents, employs human lawyers to supervise them, and offers legal services to enterprise clients. It is also creating AI agents that can monitor other AI agents while they perform their tasks.

The company charges based on results instead of billing its clients by the hour, unlike the rest of the industry.

Norm is one of many legal AI startups that have emerged in recent years, such as Harvey and Legora, seeking to capitalize on the need to automate tedious work.

Other investors in Norm’s Series C include Bain, Craft Ventures, Coatue, Vanguard, New York Life, TIAA, Tony James (former president and COO of Blackstone), Jeff Hammes (former president of Kirkland & Ellis), and Fenwick LLP. The fresh capital will be used to help develop the product and hire more lawyers.

The company has raised more than $260 million in funding to date.
