Max Levchin, the PayPal co-founder, is leaving Google just after a year after the Web giant.
Google also plans to shutter almost all of Slide's applications AllThingsD first broke the news of Levchin's departure and the elimination of the Slide-created apps., a picture-sharing service the company launched just last week.
"Max has decided to leave Slide and Google to pursue other opportunities, and we wish him the best," a Google spokeswoman said via e-mail. "Most of the team from Slide will remain at Google to work on other opportunities."
A note on the Slide Web site disclosed that several other applications will be "retired" as well. They include Slideshow, SuperPoke! Pets, Video Inbox and Pool Party.
"We created products with the goal of providing a fun way for people to connect, communicate and share," the company said. "While we are incredibly grateful to our users and for all of the wonderful feedback over the years, many of these products are no longer as active or haven't caught on as we originally hoped."
The one Slide service that Google plans to continue is Prizes.org, which connects people who are seeking help with a problem to those who can offer a solution for cash.
Levchin's departure is surprising, given Google's recent push into social networking with Google+. But Levchin didn't play any sort of public role in launching the new social network, and it's unclear if he played a significant role in the creation of it. What's more, when Photovine launched, it would have logically been integrated into Google+. But that never happened.
