Startup Idea: Server Side Script Connected Button Startup Idea

Startup idea to build a bootstrapped project, similar to airnoise.io, where a physical button linked to a user account and server-side script can be employed for various tasks. The application offers a different tier system for services that is depending upon the user's subscription.

This is a great example of an interesting bootstrapped project. With a free account, users can file up to 15 complaints a month; for $5 a month, they can file unlimited complaints. The button costs $24. The guy running the project has a full time job too. I do think the price point is too low, but still, it’s very interesting.

I wonder what other ways a button connected to a server side script and a user account could help.
