That’s a very good point of testing the product idea with the landing page. With one of my teams we setup a landing page, but we decided it is more cost effective to do develop the MVP in an agile iterative way and attracting with it our potential customers, than investing in identifying the ideal customer to test the product idea. Our main set back in testing the idea with a landing page was that we actually needed to identify our potential early adopters to get a relevant feedback on our product idea. How do you actually identify these early adopters that could give you the early feedback you need?
