Has anyone here successfully launched a SaaS product like this? How did you get your first testers. I will not promote

This might sound ridiculous, but I built a product without thinking about how to sell it. No pricing strategy, no launch plan—just the idea that it’s something I really wanted to use.

It’s a help desk/ticketing system for small businesses and startups. I found most existing options either way too expensive or missing basic features I knew I could build myself. So I spent the last four (five?) months making something that fits my needs as a small software company.

Now comes the real challenge: finding actual users.

We’ve had interest from a few companies, but everyone is "too busy" to actually try it. I don't want to jump straight into selling without getting real feedback from users first. We tried some beta software forums, but the only feedback so far was from someone who didn’t like the name.

If you were in my position, where would you go to find engaged beta testers?
