Cooley, a leading law firm, built GO Public with ChatGPT to automate IPO preparation, freeing lawyers to focus on strategic decisions.

Cooley, a global law firm specializing in capital markets and IPOs, has developed GO Public, a proprietary AI tool built on ChatGPT Work. This system automates key aspects of IPO preparation, allowing lawyers to focus on high-value strategic decisions rather than manual data processing.

## The challenge of IPO preparation
An IPO involves thousands of tasks and immense data processing. Before GO Public, lawyers often started with precedents from similar companies and adapted them manually. This process was time-consuming and diverted attention from critical strategic work.

GO Public changes this by integrating ChatGPT Work to analyze information, synthesize precedents, and create tailored starting points for lawyer review. The system combines client-provided data, public sources, and curated precedents to streamline the initial stages of IPO preparation.

## How GO Public works
Cooley's legal engineers and practitioners collaborated to translate the firm's capital markets expertise into an agentic system. The workflow includes:

1. Automated data synthesis: ChatGPT Work processes large volumes of information.
2. Controlled agent tasks: The system defines which steps agents can perform automatically.
3. Lawyer review points: Identifies where human validation is required.
4. Curated precedents: Integrates insights from previous analyses.

## Impact on legal work
GO Public allows Cooley to redirect lawyer and management time toward substantive work that drives an IPO. The system provides a strong starting point faster, enabling lawyers to spend more time applying judgment and thinking strategically.

For management teams, this means less time spent on preparation and more focus on running their businesses. The tool helps balance the competing demands of IPO preparation and day-to-day operations.

## The future of capital markets practice
Cooley sees GO Public as a model for transforming capital markets work. The collaboration with OpenAI combines legal expertise with AI engineering to rethink how this work gets done. The firm envisions extending this approach beyond IPOs to other capital markets transactions.
