Eugen Rochko, CEO and founder of decentralized social network Mastodon, is stepping down after nearly a decade at the helm and walking away with a sizable exit payment.

"Mastodon grew beyond any of my expectations," he said. "The past two years especially have been overwhelming, and my mental and physical health have taken a dip."

Rochko's move has, by his own admission, been a while coming. In April 2024, the establishment of a US nonprofit was announced with a governing board of directors that included Twitter co-founder Biz Stone. Rochko also announced that his ownership of the trademark and other assets were headed to the nonprofit.
