AppSumo Briefcase is a curated subscription bundle of premium software to help founders grow their business.
I am an AppSumo customer for almost 2 years and love it so much because of their great bargaining skills, customer support and ability to provide us great SaaS tools at highly affordable rates.
All the included SaaS tools are of premium quality and highly useful and available at highly affordable subscription fee.
Nothing as such
With Briefcase you get to pick and choose the tools you need to run your business - some you use daily. This is especially huge when there are products you don't use everyday but are nice to have in your arsenal of tools for when you do need them.
Access to a suite of tools to get your business growing bundled into a single low monthly price.
