I have an interesting question. Say there is an already established business that has more than proven the idea is viable. What does it take to... join the same market space? Can you offer the same features at the same price? Can you offer the same features at a lower price? Can you offer less features at a lower price? Are there cases where there is only room for one player and no matter what you do, you will not be…
Short answer: let the data do the talking. How big is the market? Have you driven paid/organic traffic to a landing page? Have you tested any funnels? Have you gotten feedback your prospective customers?
You can do all these things with a minimal investment.
