This is cool, I was in a similar position when I was going to try to raise some money for a potential product (which I didn’t end up doing…). I was thinking about putting something together like this for fun out of the hundred or so of decks I downloaded and had found online, but wasn’t sure how to go about requesting permission from all the deck creators and even managing how to find them. So I didn’t go through with it.
The fact that you were able to get permission from all these people, with an order of magnitude more decks than I had is astounding! Kudos, do you mind if I ask about the secret sauce to how you were able to get all these deck authors to agree to let you use these on your site?
