Tumblr founder and CEO David Karp will step down before year-end, handing the reins to president and chief operating officer Jeff D’Onofrio.

Karp shared his farewell to employees in a Tumblr post, saying in part: “I look back with so much pride at a generation of artists, writers, creators, curators and crusaders that have redefined our culture, and who we have helped to empower. There are no words, though, that can express how sincerely grateful I am for the privilege of working with you. This team and place has been my family and home for most of my adult life. That I have gotten to spend this time working with people so spectacularly talented and unstoppably optimistic is a blessing I hope you have shared and will continue to share.”

He continued, “I beg you to understand that my decision comes after months of reflection on my personal ambitions and at no cost to my hopefulness for Tumblr’s future or the impact I know it can have. The internet is at a crossroads of which this team can play a fundamental role in shaping. You are in the driver’s seat, and I am excited to see where you go.”

When Yahoo and AOL combined to become Oath earlier this year, there was no mention of Karp’s role.
