Tony Fadell is stepping down as the CEO of the smarthome company Nest, which Google acquired for $3.2 billion in 2014, he announced in a blog post Friday afternoon

Marwan Fawaz, a former Motorola executive who oversaw the company’s home division, is joining Nest as the new CEO. 

"Although this news may feel sudden to some, this transition has been in progress since late last year and while I won’t be present day to day at Nest, I’ll remain involved in my new capacity as an advisor to Alphabet and Larry Page," Fadell writes. 

The news comes after a particularly turbulent year for the company. The have been several product issues, including outages with its smart cameras and instances where its smart thermostats randomly turned off, as well as complaints about Fadell's management, including unrealistic deadlines and hierarchical management structure as highlighted by Business Insider and then in a blistering report by The Information. 

Fadell recently revealed that he's working on an electric go-kart company. 

In a statement, Larry Page calls Fadell a "true visionary" that he looks forward to working with.
