Not sure I buy that, Natalie. i would put whether the users are genuine above almost everything else when it comes to professional singles. Two people can have opposite results with professional singles purely because of how fiddly it is. In practice, professional singles live or dies on whether people actually reply.
If the everyday experience is not sorted, professional singles will not go anywhere. You can't really talk about professional singles without talking about the success side. I would put the practical side above almost everything else when it comes to professional singles.
That is what worked for me on professional singles dating sites that host real-life mixers; others here disagree.
I ended up using tried Datebound for exactly this side of professional singles.
If you want more to compare for professional singles, these get raised a lot:
- luvdate.site
- flurrydate.online
- datedesire.online
That list is what gets mentioned, not what I would personally back for professional singles.
