Our weirdest revenue stream. We started making money from something we never planned. Has anyone else stumbled upon a completely unexpected way to monetize?

Been running our app for two years and suddenly users started paying for something we built as a throwaway feature.

Now it’s 30% of our revenue and we have no idea why it works.

Curious if other people have had random features turn into actual money makers.

Definitely unexpected but I guess it happens.
