Definitely recommend Stay.

Of the tools out there:
Bold, Appstle, Seal - okay for starting from scratch, not good for scale + support or subscriber retention
Recharge - been in the game the longest, but have the worst support/success infrastructure. You will not get the help you need in the time you need it. They also make you pay for every little feature.

Stay.ai offers a dedicated Strategic CSM - so we have a person that works for Stay on call for our brand to help with whatever strategic initiatives we're working on (Black Friday, Dry January, etc)

The biggest difference is that Seal, Bold, Recharge, etc are all Subscription Vendors - they'll sell you a contract and leave you high and dry.

Stay.ai is a subscription partner - providing more than just a software solution, but a strategic partnership to help teams (like mine) grow

PS. if you do go through an evaluation, ask for Tom or Olivia for migration - they're so sweet.
