Looks nice, but I'd never not pay for a service because you're paying somehow, or the service won't be around for long.
Here's our pricing page (with paid tiers - you have to scroll down): https://www.profitwell.com/pricing
If you're curious around the science/data that went into this (the longer story), you can check out a talk I gave at our SaaSFest conference: https://pi.wistia.com/medias/jdywlrpowl. We used our Price Intelligently software to determine market willingness to pay/feature value before writing too much code.
As always, let me know if you have any questions. Happy to help.
Thanks for the info!
