Sell Webflow Projects on a Subscription Model (Monthly Income)

Marc from my Patreon community asks: I'd be interested in your opinion about https://www.designjoy.co. What do you think of this concept? I've already talked about it with a friend and we came to the conclusion that we couldn't imagine anything more stressful 😂. Nevertheless, I find the idea of productization exciting. Especially if you are a client yourself and only receive prices on request and after a meeting and then negotiate around forever. What do you think about that?
