Is it just a matter of targeting different customers and selling to them? Better marketing efforts? Or do you think they usually come out with a superior product off the bat?
Ex: Clearbit founded 4 years after FullContact, then newer competitors like Lusha Ex2: Middesk growing rapidly where Trulioo/Cognito had a 7 year headstart
Markets and technologies are not bounded spaces. They only seem "crowded" because all the existing players are doing similar things, when in fact the entire pie could be made much bigger if you do things a different way.
