A: Hi,

Thanks a lot :)
So I'' try to answer on your questions.

Great product!

1) Let's say I but 1 code with 7 users. In the future, if I want to increase users how much will it cost me?

It will cost you $10 / month per additional user

2) Have you raised any funding yet? Just want to make sure that this awesome product is here to stay.

No we have not. We have been around 2015 and bootstrapped since then and we are not planning to go anywhere except become larger product with more awesome features ;)
