Facebook App Growth Rate: Amazin’ Giftbox

My friend Gil and I launched a facebook just under a week ago called the Amazin’ Giftbox.

It’s a simple free gift app with a twist — instead of sending gifts consisting of little graphics we create, we allow you to choose any item on Amazon.com and turn it into a virtual gift. Send a Segway, a book, a Camaro, flowers, diapers, anything. Amazon really does sell it all.

Anyway, it’s been interesting to see how viral apps can grow even now as app fatigue has started to set in. (See graphs at right.) Started from zero less than a week ago, we’re now at 3,562 users with zero promotion (beyond demoing the app a few times, which had minimal effect on the numbers.)

Top graph shows # of users added per hour, bottom is total user growth. It’s only a week, but still interesting.

Built from the ground up to be viral, Amazin’ Giftbox has outgrown our first app, Amazin’ Wishlist, which had a 4 week head start!
