When considering product development it may help to focus on an early adopter group [1]. Use that to grow and add more features. Having a group of early adopters (happy test subject) is crucial.
"So, the minimum viable product is that product which has just those features (and no more) that allows you to ship a product that resonates with early adopters; some of whom will pay you money or give you feedback."[2]
While you could argue that some products appeal to certain segments (unexperienced users vs more experienced users), there still is no reason why you couldn't use that customer group and refine your existing product, create a secondary product (addition), or a new one entirely focused to that 'other' customer group. In this example, a new product focused to the more experienced user might be easier as that is exactly who you focus on for an early adopter group.
