I turned away my first potential client because they were not my target market. Did I do the right thing?

I recently soft-launched https://warpurl.com/ and today I had my first potential meeting with a client. They turned out to be a Consumer(B2C) and I am targeting(B2B).

I am in the early access phase with the product basically built. It was designed with the intention of B2B, after signing up it creates a "server" for that client. Everything is actually serverless on AWS, but nonetheless creating the infrastructure and resources is still "expensive" not in cost but in work and resource limits per account. Everything is automated at least.

So at the end of the engagement, I explained that they are not really my target market. That I am prepared to give significant discounts, like free for 1 year or the smallest plan free for life to clients that really use the system (B2B) in the early access.

So I knew what the tiebreaker would be; asking if they would be willing to pay the smallest plan fee if they really insist that they want this, and their answer was of course no.

I think I made the right call? It would have been nice to get that first client but I don't think I would have gained any value from them?

The main reason I am in early access with a ready-to-launch SAAS product is that I want a few closer companies before really launching and putting the product out there, is this belief misplaced?
