These ideas are called swamp in our framework because they will drain your energy, time and motivation and get you no where.. Here are a few real examples, submitted by fellow bootsrappers. They seem totally legit or even great on the surface:
Simple and intuitive inventory managment software for small ecommerce sites owners with integration to major platforms such as woocommerce and shopify
A music/sound platform that host AI generated music to keep people focused in productivity work.
A habit tracker, but concentrated on fighting unhealthy habits instead of building positive ones.
Restaurant discovery app as a marketing platform for businesses and 2for1 coupons for customers
a historical forex data api for developers, that returns clean data from central banks
But these are all ideas where we have many similar products with zero or very low engagement, meaning people have tried and tried but no one really cares.
Without validating your idea it's extremely easy to end up chasing one of these swamp ideas and wasting months or even a year of your life in the process.
Remember, everything has an opportunity cost and shitty ideas have a huge one
The same energy that got you to build an MVP nobody cares about, might have given you an MVP that is generating revenue already.
Context: We failed more times with our ideas than we would dare to admit and we wanted to build a platform that ensures that others don't have to and can find solid (profitable) ideas with less suffering and time wasted.
