I purchased Linke early on and I am glad I did.

I have a couple of link shorteners & bio-page builders but this is my favorite.
It's easy to use.
Setting up C-name is a breeze.
Creating bio pages is easy and fun.
Lots of features other similar apps don't have.
Unlimited links, custom domains and bio pages!
Analytics is pretty cool.

Also noticed some improvements - like downloadable VCard !!
Awesome!

Overall, this is one of the best Appsumo deals.
