Help Makers learn how to respond to challenges by taking part in 'war games'; exercises that are carried out to test or improve tactical expertise.
Makers, entrepreneurs, side-project enthusiasts.
It would probably be a chatbot that sets scenarios that Makers might face and asks them to choose between a number of options, which leads to consequences and more decisions to be made until the venture is either a success or failure.
Start with a free chatbot service (embedded on the landing page).
Map out the various scenarios.
Test with Maker community.
Decide on a validation point (probably number of users/interactions allowed on free service).
Then move to paid chatbot service.
Figure out payment model (small payment each use, lifetime subscription, ask at the the end (buy me a coffee-style))
Promote to Maker community on Twitter, ProductHunt, indiehackers, etc.
