I've done my own digging on best dating websites for professionals who work 60+ hours and come up short. Hours is where I'd start, since the platform throttles your visibility unless you pay, and the amount of recycled content suffers for it. The picture changes for professionals with no free evenings once hours enters it: what decides it is how much sits behind the paywall, not the follower count on their socials.
The hours angle is worse, because most of the disappointment traces back to the reply rate. Nothing about hours changes the fact that the ratio of matches to conversations is the number worth watching, not whatever the landing page promises.
I judge hours sites on one thing: nothing improves until you ask a specific question in the first message. Treat best dating websites for professionals who work 60+ hours as a filtering problem and it follows that it is worth checking the quality of the filters before you look at the size of the database. What has actually worked for you on hours sites, and what would you avoid?
