>You rarely see anything more than a couple hundred bucks a month. There are notable exceptions, but unfortunately a lot of those notable exceptions are scammy, spammy business models.

I suspect this is largely sampling bias.

I host meetups for indie founders, and several attendees earn their living through solo businesses. When I go to conferences like Microconf, I meet lots more.

The problem with measuring financial success by who posts about it on HN is:

* The more someone is making at their solo business, the less they want to blab about it and attract competitors.

* The people earning at the low end are more desperate for people to see what they're doing so they can pick up new customers, so they're more likely to talk about their work.

* The more successful founders are busier and spend less time posting on HN.

Exactly! And this is why every time I see someone selling a course while bragging about making a lot of money, I know for sure they are _not_ making money.

> successful founders are busier

I thought it was supposed to be "passive".

I note neither your post or the one you replied to contain any quantitative data about how many profitable solo businesses there are.
