A business doesn't have to be perfect prior to initiation. The model can be backward, the rates wrong, the clients untenable. Only by making mistakes and rectifying them, one by one, will you arrive at a solid business.
Again Faster was founded as an ad-supported blog (with no ads). CrossFit, Inc. was founded as a local gym (with no Affiliates). Neither exists as it was envisioned.
