Uber founder and former CEO Travis Kalanick is stepping down from the company’s board of directors.

“Uber has been a part of my life for the past 10 years. At the close of the decade, and with the company now public, it seems like the right moment for me to focus on my current business and philanthropic pursuits,” Kalanick said in a Tuesday statement. “I’m proud of all that Uber has achieved, and I will continue to cheer for its future from the sidelines.”
