A Meta executive who co-founded Diem digital currency is set to leave the company at the end of this year to embark on new projects.

David Marcus said in a blog post Tuesday he will be leaving the parent company of Facebook after seven years.

Marcus started at the company in 2014 and worked for the Messenger platform for years. A trusted lieutenant to CEO Mark Zuckerberg, he moved on to the company’s digital wallet service, Novi, and then co-founded Diem digital currency, Bloomberg reported.

“While there’s still so much to do right on the heels of hitting an important milestone with Novi launching — and I remain as passionate as ever about the need for change in our payments and financial systems — my entrepreneurial DNA has been nudging me for too many mornings in a row to continue ignoring it,” Marcus said.
