Corporate identities evolve, just like anything or anybody else. The first logo of Pinterest was made with Bello, back in 2010. Meanwhile, after reaching more than 300 million users in their first decennium, this social media company revised their logo a couple of times already. You can find more information about their logo evolution online, for example at 1000 logos.

ps.
Did you know that also the first logo of Airbnb was set in Bello? No? Now you do.
