Yes, we only set up companies for a year. During that year, all employees of the company can start up a challenge by using the company coupon. After the one-year period the contract can be prolonged with a year or can be stopped.
When the contract has ended, the company coupon will be deactivated and no new challenges can be linked to the company. The open challenges created via a company coupon will remain open until the challenger will close his or her challenge.
