The current trend of migration from blockchain to artificial intelligence is undeniable. Every week, there are reports of companies or individuals abandoning the cryptocurrency industry or incorporating AI into their portfolios. Bitcoin miners are transitioning from mining to focusing on AI infrastructure, and venture capital firms are now funding AI companies instead of crypto firms.

However, it is unusual for leading team members to leave one company and join another in the same vicinity. This is precisely what has happened to the senior marketing team at crypto exchange Coinbase, with several members joining San Francisco-based OpenAI, the creator of ChatGPT, over the course of a year or so. Although Coinbase has a large marketing team, with around 150 staff members, six senior roles have been filled by former Coinbase employees at OpenAI. The migration of marketing talent began with Sarah Russell, who joined OpenAI as VP of integrated marketing and operations in November 2024, after spending over a year at Coinbase.

A month later, Kate Rouch became OpenAI's chief marketing officer, having previously held the same role at Coinbase for three and a half years. Rouch was followed by Elke Karstens, who joined OpenAI as head of international marketing in March 2025, after a brief stint at a London-based paytech startup. In September, two more transitions occurred: Kaitlin Gianetti became head of integrated marketing management at OpenAI, and Amy Robbins joined as brand insights lead, both having left Coinbase.

Most recently, Nina Mogavero joined OpenAI in December 2025 to work in marketing strategy and operations, a month after leaving Coinbase. A person familiar with the situation described the exodus as no coincidence, citing Rouch as the key figure in enticing former Coinbase colleagues to join OpenAI. A Coinbase spokesperson downplayed the departures, stating that the marketing team is over 150 people and that the departures are normal. OpenAI did not respond to requests for comment.

This trend is not limited to marketing, as other departments have also seen AI as more attractive than crypto. Tom Duff Gordon, the former VP of international policy at Coinbase, left to become OpenAI's head of EMEA Policy.

Other Coinbase alumni have also joined OpenAI, and the company is not the only machine learning firm to win over Coinbase marketing talent.
