I do a free beta, then various paid betas. The goal is also to find a price point. A user can either leave feedback in my betas and get that month free, or they can pay. The idea that all they have to do is give feedback for a free service usually works well... Eventually, when it's easier to pay, some users will start leaving money instead if feedback. At some point I'll raise prices a bit and stop the feedback for service system. I've done this for: https://projectpiglet.com/ https://projectpiglet.com/ and https://easy-a.net/ https://easy-a.net/ And a few others, it's always fairly successful - assuming you have a decent landing page and you can advertise the site in your target market for cheap / free.
