Startups, whether entrepreneurial or intrapreneurial, need to carefully parse out the enthusiasm they evoke and earn. Here is a short taxonomy to consider:
The enthusiasm of friends and families
The enthusiasm of your team
The enthusiasm of industry experts
The enthusiasm of investors
The enthusiasm of early adoptor customers with placed orders
The enthusiasm of later adoptors with placed orders
It is wise to consider each in their own context, not generalizing one to the other. Often, the synergy of them together paints the richest canvas for moving forward.
