I know the guy behind Grailed from MFA and he definitely doesn't have any venture capital or money. It's just one guy and he has a partnership with PayPal where they are covering the fees for a limited time.
Let's be real though, how hard would it be, at the end of your extremely long work day, to come home, and write a one paragraph update. It would take 30 seconds to boot up the computer, 4 to open the browser, 2 to get to styleforum, 1 to get to the posts, and a minute to type a reply.
Mauro, I'll take that job now. I'm a web designer so I can help you with that aspect. Oh, I do photography too. My salary requirements are one shirt per day until I have all of the shirts and then money.
