If it's SaaS, you should be monetizing from day one. An MVP in SaaS is the minimal product that people will pay for, that's the starting point. You evolved the product from there.

There's nothing wrong with an exclusive, it gives you an opportunity to execute well and align a strong public announcement with a high-profile client, if picked correctly.
