San Francisco – September 17, 2026 – Cooley today announced the launch of Cooley GO Public, a proprietary AI-enabled offering developed by Cooley’s capital markets lawyers and legal engineers to be used with ChatGPT Enterprise to transform how companies prepare to enter the public markets. Cooley was a design partner with OpenAI to build the new experience.

The first GO Public offering enhances the Form S-1 drafting process using a system of purpose-built AI agents. Combining client information and agent-powered research with Cooley’s know-how, judgment and deep market experience, GO Public accelerates research and drafting so working groups and management teams can focus on critical strategic questions sooner.

“GO Public marks a major advance in legal service delivery, focused in an area we know deeply and designed to give clients greater speed, certainty and insight,” said Rachel Proffitt, partner and CEO of Cooley. “GO Public reflects our ongoing commitment to lead our industry as legal work becomes more technology-enabled and outcome-focused while remaining deeply grounded in human judgment. We’re excited to build on this model across our practices as we expand how AI-enabled legal services can take shape.”

Purpose-built for each IPO

Drawing on Cooley’s decade-long leadership at the top of the US IPO market[1], GO Public is designed to:

  • Start with the client, not a precedent. Build the initial draft leveraging company-specific information and deep research, using Cooley drafting guidance, detailed background instructions and curated precedent to inform the work.
  • Accelerate speed to quality. Prepare an initial, bespoke S-1 draft in minutes rather than days, allowing our team to apply substantive judgement and experience to issues sooner.
  • Adapt as the deal evolves. Update the S-1 as transaction terms change, with thoughtful prompts and targeted review.
  • Increase efficiency and predictability – including around cost. Give management teams more time to focus on running their businesses and other aspects of the IPO process while supporting more predictable planning around time, resources and spend.
  • Keep judgment with Cooley lawyers. Our experienced capital markets lawyers are involved every step of the way, including the legal analysis and the final work product.

Rethinking capital markets execution

GO Public’s underlying architecture also has potential applications beyond IPOs across a variety of equity and debt capital markets transactions.

“GO Public is our vision for the future of capital markets practice,” said Dave Peinsipp, partner and co-chair of Cooley’s global capital markets group. “Our collaboration with OpenAI has allowed us to rethink how this work gets done – moving lawyers and management teams more quickly through intensive preparation and into questions that require judgment, market experience and strategic thinking. We see enormous potential not only for IPOs but for capital markets transactions more broadly.”

“We want to give firms the ability to build AI around the expertise that makes them distinctive,” added Jason Boehmig, GM Legal Industry at OpenAI. “Working side by side with Cooley, our forward-deployed engineers are helping turn that expertise into tools like GO Public – combining frontier intelligence with the firm’s own data, workflows and ways of working to support lawyers through complex, high-stakes transactions.”

Extending the model through Cooley AI

GO Public is the first in a series of capabilities Cooley is developing through Cooley AI, its AI services company focused on making the firm more AI-native – enhancing how work gets done while rethinking how legal services are staffed, priced and delivered, with human judgment and client relationships at the center.

Cooley AI brings together legal, AI, data, product, engineering and operational skill and knowledge to put that strategy into practice and create more responsive, insightful and predictable experiences for clients.

Beyond capital markets, Cooley AI plans to focus initially on private companies, funds and M&A before expanding into additional practices.
