Nest co-founder and former CEO Tony Fadell left in 2016 after reports of strained relationships with Google and Alphabet executives. Fadell's exit was a tough time for the startup, but Nest today has a stronger lineup of top-selling DIY products and more support from Google. Basically, the Google brand is strong enough to weather this change. Here's why.

Nest was founded in 2011 by Tony Fadell and Matt Rogers, two former Apple employees who worked on products like the iPad and the iPhone. Fadell, Nest's first CEO, transitioned to an advisory position at Google's parent company, Alphabet, in 2016 and later left the company entirely. Matt Rogers left Nest in 2018.
