ChatGPT Work speeds up Cooley's IPO legal work

Cooley, an international law firm known for capital-markets and IPO work, is the subject of an OpenAI case study describing GO Public, a proprietary product the firm built on top of ChatGPT Work. In 2025 Cooley advised on 180 deals worldwide totaling more than $51.5 billion in deal volume; the piece adds that Cooley has a decade-long run at the top of the US issuer-side IPO market and has advised on more venture-backed IPOs than any other firm over the past 20-plus years.

GO Public runs on what the firm calls an agentic harness: it draws together client-provided information, relevant public sources and Cooley's own curated precedents, then follows a controlled workflow that sets out which steps agents can perform automatically and where lawyers must review and validate the output, according to David Wang, Cooley's Chief Innovation Officer. Before GO Public, teams typically started from a precedent deal at a comparable company and adapted it; the new system instead lets Cooley start from the client's own information, producing what Wang describes as a more tailored starting point built on accumulated 'baked-in know-how' from prior deals.

Dave Peinsipp, partner and co-chair of Cooley's global capital markets group, frames the goal as 'speed to quality': GO Public is meant to get lawyers to a strong starting point sooner so they can spend more time on judgment calls, challenging disclosure and strategic decisions, rather than simply doing the same manual sorting work faster. The firm argues the saved time also benefits client management teams, since IPO preparation competes for the attention of executives who are simultaneously running the business.

Peinsipp calls GO Public 'our vision for the future of capital markets practice' and says Cooley sees potential to extend the approach beyond IPOs to capital markets transactions more broadly. The case study gives no launch date for GO Public, names no specific client or IPO where it has been used, and provides no usage, adoption or time-saved figures for the product itself.

Key facts

  • Cooley built GO Public, a proprietary IPO-preparation product running on OpenAI's ChatGPT Work.
  • In 2025 Cooley advised on 180 deals globally worth more than $51.5 billion, and says it has advised on more venture-backed IPOs than any other firm over the past 20-plus years.
  • GO Public's agentic harness combines client information, public sources and firm precedents into a tailored starting point, with a workflow that sets where lawyers must review and validate the output.
  • Cooley executives describe the goal as 'speed to quality': reaching a strong starting point faster so lawyers spend more time on judgment and strategy rather than manual sorting.
  • The case study gives no launch date, no named example deal, and no usage, adoption or cost figures for GO Public itself.

Why it matters

GO Public is a concrete example of a professional-services firm building a proprietary product on top of ChatGPT Work rather than using it as a general chat assistant: an agentic harness with defined automatic steps and mandatory lawyer checkpoints, applied to a high-stakes, document-heavy workflow where Cooley already leads the market. It shows OpenAI positioning ChatGPT Work as an integration layer for domain-specific enterprise tools in a profession the case study itself calls 'relatively change-averse.'

Who it affects

Cooley's capital-markets lawyers and the management teams of companies going public through the firm, according to the article. OpenAI gets a customer story aimed at other professional-services firms considering ChatGPT Work for similarly document-heavy, review-intensive workflows.

How to use it

GO Public is Cooley's own internal product; the case study describes no way for outside clients or other firms to buy or license it. It is built on ChatGPT Work, OpenAI's enterprise-tier product, whose own pricing and terms are not detailed in this piece.

How solid is it

The account is an OpenAI-published case study built on quotes from two named Cooley executives, David Wang (Chief Innovation Officer) and Dave Peinsipp (partner and co-chair of the firm's global capital markets group), so it is promotional by design. The 180-deals and $51.5 billion deal-volume figures are Cooley's own reported numbers for 2025, not independently verified in the piece. No specific IPO or client is named as a GO Public example, and no metric quantifies the 'speed to quality' claim.

Risks and caveats

The case study gives no launch date for GO Public, no cost or licensing figures, and no measured outcome such as time saved or number of IPOs run through the system. The framing of results (faster preparation, better focus, 'speed to quality') comes entirely from Cooley and OpenAI's own language rather than an outside audit, and the workflow described still routes final review and liability through human lawyers at every step.

“The amazing thing about integrating ChatGPT Work into GO Public is that it brings intelligence to this very large array of information that had to be manually sorted before.”

— David Wang, Chief Innovation Officer at Cooley
