I wouldn’t say “beta” unless your software is really buggy and subject to change. Then I would make that really clear (“our software is incomplete and unstable”) and accept that I’m going to have less users. You could also say version 0.x, which isn’t very noticeable. “Beta” has kind of lost its meaning, since plenty of really buggy software has been released for a long time, and plenty of amazing software is still in beta or 0.x because the developers want it to be absolutely perfect.
