for one you can get started with a private repo without paying for it. You can securely share it with your entire team and not pay one cent, and you can do that just by creating an account on gandalf.io.

Secondly, for those who're starting out using dockers, a four docker plan is optimal because most folks use a combination of containers inheriting from public and private repos. So you can pay $4 per month for 4 repos using gandalf.io whereas you have to pay a minimum of $7 per month for docker.io's service.

Thirdly, this is just the beginning and we're working on a roadmap of features, some of which docker.io might not provide.

Fourth - support is important when using a service, and support can have a specific flavour when using a startup offering. try gandalf.io to understand the flavor :) !
