Have any companies in the market been successful going the premium route? A service that costs a lot but is designed for the best user experience and outcomes?

For a dating service company not to be overly incentivized to keep users swiping forever, a membership model like with a country club could also work: a large upfront fee to join and then maybe a smaller reoccurring fee to maintain membership.
