I am working on a SaaS now and the amount of effort required to build a product for 1, 200 or 2.000 persons is roughly the same. There isn't 200 persons out of 20.000 who will accept a sub-par product and pay for it. However, once you get a few people paying for it, there are already more who you just need to discover.
Instead of 200, focus on 5 potential customers only.
