Lyft Co-Founders to Resign; David Risher Is Named CEO

Lyft’s co-founders said on Monday that they would step down from their day-to-day responsibilities at the company, which has struggled through layoffs and disappointing financial results even as Uber, its biggest rival, has strengthened.

The founders — Logan Green, Lyft’s chief executive, and John Zimmer, its president — are resigning after more than a decade with the company but will stay on its board of directors, they said.

David Risher, the chief executive of a nonprofit called Worldreader and a member of Lyft’s board, will replace Mr. Green as chief executive. Mr. Green’s last day will be April 17, and he will become the chairman of the board. Mr. Zimmer will depart his current role at the end of June and become vice chair, the company said.

“As I pass the baton to David, I want to share this: We continue to have an incredible opportunity to push the boundaries on how transportation can help connect people and build a better future,” Mr. Green said in a blog post.
