I may be wrong, but my assumption is that you are assuming putting your story on something like indie hackers is a lost marketing opportunity.

But I'd say a large percentage of successful small saas products are very niche and would not benefit in the least from talking about it in a public forum.

In my case, none of my customers would be reading anything like indie hackers so I have no reason to get the word out through those channels. It would just invite competition without returns.
