Several Coinbase Marketing Executives Join OpenAI Over Past 18 Months

Six senior marketing executives from cryptocurrency exchange Coinbase have joined artificial intelligence company OpenAI over the past year and a half, according to CoinDesk. The moves include Coinbase's former chief marketing officer and other senior roles.

The transitions began in November 2024 when Sarah Russell joined OpenAI as vice president of integrated marketing and operations. She had previously served as senior director of integrated marketing at Coinbase. Earlier in her career, Russell worked at Meta's headquarters.

In December 2024, Kate Rouch became OpenAI's chief marketing officer after spending three and a half years in the same role at Coinbase. Elke Karstens joined OpenAI as head of international marketing in March 2025, following a three-month stint at paytech startup Finom.

Karstens had previously worked at Coinbase and spent over 10 years in marketing roles at Meta. The following September saw another two transitions: a director of integrated marketing at Coinbase became head of integrated marketing management at OpenAI a month after leaving Coinbase, where they had worked for just over four years.

This individual also previously worked as a brand marketing executive at Meta. A senior manager of insights at Coinbase joined as brand insights lead at OpenAI directly after leaving Coinbase, where they had spent three and a half years. Most recently, a marketing and strategy professional joined OpenAI in December 2025 to work in marketing strategy and operations, a month after leaving Coinbase where they had spent three years in marketing and strategy.

OpenAI has hired personnel from Coinbase in other areas beyond marketing. Earlier this month, the former VP of international policy at Coinbase left to become OpenAI’s head of EMEA Policy. Other Coinbase alumni who have headed to OpenAI include a product manager who joined the AI firm in April 2025.

The head of design at decentralized trading platform Base left Coinbase in October 2025 after just over five years. A data science professional left Coinbase in September 2024 to become a member of OpenAI’s data science team.

A person familiar with the situation stated that the moves were connected, describing Kate Rouch as the key figure in recruiting former colleagues. The person noted that Rouch had hired many of them or brought them from Meta.

“To be fair, she hired a lot of them or brought them from Facebook.”

A Coinbase spokesperson stated that the company's marketing team consists of over 150 people and described the departures as normal personnel changes. The spokesperson added that while some employees left to join OpenAI in the past year, the company wishes them well.

CoinDesk reported that Coinbase maintains a 150,000-square-foot office in San Francisco, where OpenAI is also based. OpenAI did not respond to requests for comment, and Kate Rouch did not respond to a request for comment. In a related move, the marketing lead behind Coinbase’s Base layer-2 network left after nearly five years at the exchange to head startup marketing at AI lab Anthropic earlier this month.
