“Is it suitable for me, independent from where I am in my career?”

Sure it is! We created the materials particularly with three types of users in mind:

– College students. I.e. people who are approaching the last part of their studies and getting ready for their first job. The thinking here is that college often lacks a good preparation for landing a work environment. Our program helps you fill that gap.

– Early Career Professionals. I.e. people who are in their 1st or 2nd job and experiencing their real strengths and areas for development. Our offering helps them to both further enhance their talents, and address their development needs.

– Mid Career Professionals. I.e. people who are at a point that they want to make a choice. Pursue what you are doing? start another job? Our programs are very useful in terms of addressing the latest needs and requirements in work life. CareerCube.io is keen to support your up-skilling or re-skilling.

We recently also got some members who actually are at the last phase of their careers and were looking for ways to get ready for stepping up their ‘fit’ to job requirements, up-skilling them to complete their careers with success.



“Is it suitable for people living outside of the USA?”

Yes it is!

The materials are created by an international team with a lot of experience in all five continents.

Some of our recent members are based in Australia, South Africa and China. Some of them took the CareerCube.io membership to prepare for their studies in the USA. But the materials are created such that they can be used across the world.

“What are the payment methods?”

We make use of the Stripe payment method. This is a trusted global player, known for excellent security. This allows you to use any credit card of choice. In addition you can use Paypal to pay your subscription.

“Do I pay each month?”

For individual members we have two options. You either pay per month, and your membership is automatically continued each month, unless you drop us a mail before the end of the month ([email protected]). Or you take a yearly subscription and pay for 12 months upfront. When you pay annually, you benefit a 50% discount on membership fees!. Please note, that also the annual memberships continue automatically unless you give notice to us before the end of the year ([email protected]).
