[XCSme]

I have been, for about 10 years, the solo developer of https://www.uxwizz.com and there are both individuals and companies that trust projects built or ran by a single person.

I think what makes it easier in my case is that the product is self-hosted, so the clients don't have to rely on me to keep things running, plus they always have access to their data and product, even if I disappear.

Furthermore, I make sure to only release builds/publish updates that are not broken and that I am available in the days following a big release.

That being said, there have been many cases where companies (usually on the bigger side) decided not to work together because of my small company size and associated risks (but this mostly happened when discussing special uses-cases or partnerships, not when simply wanting to purchase and use the product as is).
