Cooley and OpenAI Build AI System for IPO Filing Work

Cooley said on Sept. 17 it launched an AI-enabled IPO preparation service built with OpenAI and designed for ChatGPT Enterprise. The offering targets Form S-1 drafting, one of the most labor-intensive stages in taking a company public. Cooley lawyers remain responsible for legal analysis and the final filing.

The launch places a major capital-markets practice at the center of a shift from general-purpose legal AI tools toward systems built around a law firm’s own methods, precedents and client information. Cooley developed the product with OpenAI as a design partner and is positioning it as the first capability from Cooley AI, a new services company intended to change how the firm uses technology, staffs matters and prices legal work. The move extends Cooley’s decade-long position near the top of the U.S. IPO market into legal operations and workflow design.
