San Francisco, Mar 29 : Ride-hailing company Lyft's co-founders, CEO Logan Green and president John Zimmer will transition from their full-time roles into non-executive roles, and former Amazon and Microsoft executive David Risher will become the new CEO, the company has announced.

Lyft's current chairman Sean Aggarwal will step down from his post but will remain on the board. He will serve as lead independent director.

Risher, a seasoned technology executive, will become Lyft CEO on April 17.

"Building Lyft with John over the last 16 years has been the adventure of a lifetime," said Green.

"When Risher left Amazon, Jeff Bezos publicly thanked him, vowing to 'build on the foundation you helped pour'. He is the absolute right person to build on our foundation," Green said in a statement late on Monday.

Lyft was founded in 2012 and is one of the largest transportation networks in the US and Canada.

"I am honoured to step into the CEO role at such an important moment in the company's history, and am prepared to take this business to new levels of success," Risher commented.

Risher also co-founded Worldreader, a non-profit organisation that has so far helped 21 million people read.
