It seems as though companies (targeted towards start-ups and apps) will give away free shirts to users in exchange for sharing pictures of yourself wearing the t-shirt!
The compensation is unclear, so you may just get some new shirts out of the deal - and who doesn't love free clothes?
The site is new, and so at this point is just collecting prospective models. When you sign up, you will be placed on the waiting list, BUT you will be bumped up based on the number of referrals that you get.
Join the waiting list here to get in on the ground level of this neat side hustle!
