What is the smallest/simplest product that you've seen that makes good revenue?

When I first heard of bingo card creator from Patrick Mckenzie, I was so surprised at the simplicity of the product. I thought people paid money only for complex business applications (after all, on the internet everyone expects things to be free).

Do you have any examples of simple/small products that generate revenue (yours or others’)?


Ya this is a kind of interesting phenomenon. https://www.hellobar.com/ is one that comes to mind.


does it make money though? seems like a free project?

Hm you know what I’m not sure. I’m pretty sure they used to charge for it - maybe they don’t any more.

I took a quick look at it yesterday. Basic usage is free, but many configuration options prompt you to upgrade to a premium account.

I think it’s grown now but I believe that at one point birthdayalarm.com was a simple service to get reminders about friends’ birthdays. Did it make money? Absolutely - this is from an article in the Guardian “… in 2003, Birchhad breakthrough with a greeting card site called birthdayalarm.com, and the money starting rolling in. “Birthday Alarm did work and became popular in 2003, and we were taking £10,000 a month, so it was very exciting. Then it went to £10,000 a day and we thought: ‘This is great’. Then we made £300,000 in a month, so that was the biggest turning point for us, by far,” says Birch”

wow, that much money from a birthday greetings site, incredible!

I found this one to be very interesting (6 figures a year) - https://www.storemapper.co/

Yeah I met a guy who still maintains that website within Monkey Inferno and he told me what it currently makes, it’s still doing well. Great, simple and valuable idea…
