Satoshi Okamoto Appointed as Head of B2B Marketing Japan at OpenAI

OpenAI has appointed Satoshi Okamoto as Head of B2B Marketing Japan. A seasoned leader with more than two decades of experience, Okamoto arrives from Stripe after serving as Head of Marketing Japan.

A Track Record In Marketing

According to Crustdata people data, Okamoto has spent more than a decade in marketing, including senior leadership roles in Japan at Stripe, Databricks and Pure Storage. At Stripe, a company of 16,641 employees, Okamoto held the Head of Marketing Japan title from February 2024. That role built on an earlier run in the same position at Databricks from 2019 to 2024, as well as a stint as CMO for Japan at Pure Storage.

Before that, Okamoto rose through the ranks at Akamai Technologies, advancing from Product Marketing Manager to Senior Manager, Product Marketing and Localization, and then to Head of Marketing, Web & Security Marketing Division. That progression followed years at Citrix. Okamoto studied at Meiji University.
