The Google Apps Marketplace has grown from 50 to over 300 apps in its first year.

"In the past year, we’ve had the pleasure of collaborating with many of the best developers on the web, working to make it easy for you to extend Google Apps with great apps for your businesses or school,” said Scott McMullan, Google Apps Partner Lead.

Google says it’s learnt the following things over the course of the year:

Web app adoption is accelerating across every business function and needYou value web apps that work together — what we call integrated appsIt’s harder than ever to evaluate and select the right app, given the number of new apps coming to market, and their increasing specialisation

McMullan says that the team is now working on features to make it even easier for customers to find, evaluate and deploy web apps that integrate out of the box.

"Beyond single sign-on and quick access through our universal navigation bar, our best Marketplace apps synchronise data and offer integrated features designed to keep you and your users productive as you move closer to 100% web,” added McMullan.
