I think it might be time to go beyond the idea that there are "markets" at all. That's just a vision inherited from mass-produced consumer goods that are all similar.

In reality, demand is much more malleable, and what people want and how those wants coalesce in different product categories is what defines the structure of those "markets."

People would do far better to start from first principles and understand what desires, wants and needs they want to serve, understand what products/"markets" serve those needs, and build products to satisfy them.

Unless of course you just enjoy the distribution advantage given by building something in an entrenched category. But then don't talk about your "tech" "startup" or about "innovation". You're just doing a cookie cutter product like everyone else.
