Assessing Competitive Landscape

Competition is good and even helps validate business is worthwhile.

• However, how do you determine whether you should join the competition?
• Let's say you research and find competitors that aren't very much different from another but have slight differences in pricing and high level features. Why would it still be viable for more of these competitors to exist and more to be born?
• What would you be trying to validate with landing pages if there are already competitors with different variations of pricing and feature combinations already?
