Ask HN: Which niche online businesses would you love to own?

I like email marketing companies, please don't buy them up and destroy them

Nah, the point is these businesses are so good the owner would never sell. So there's nothing to buy. It's more for inspiration, like, what does a good, neat, fun, useful, little internet business look like?

Looks like you are living your dream :) Best of luck with it!

Great one! Internet native, simple web page, low cost and clear value transfer between the company and the customer.

Edit: to make the comment more useful

I've admired 750 Words as an internet business from afar for a while now. Combo of Morning Pages being a time tested tool (with Tim Ferriss as a practitioner no less) and it being a perfect match for the internet and a small subscription (daily journaling with streaks)

The webmaster has some interesting write-ups on Indie Hackers for people wanting to know more...
