Beta versions of your products?

I’m new here so I’asking even though the question has probably been asked before (but hey I made a search)…
Do you post beta versions of your products on your website?

Usually there are no public betas available, the hidden beta boards in the forum are limited to regular beta testers.

Actually I asked this question because I saw an ad about, and I quote, Devongent beta on
Probably an old ad.

Usually we release public betas of new products or major updates. But most betas are just internal.
