Online dating could probably help a lot if it was optimized for actually providing a solution instead of maximizing profit. If these services actually manage to find a matching long-term partner, they will lose two customers.
There’s a Dutch app that’s pretty good (it’s called Breeze). Many tech orgs do find a good solution but they are usually not blitz scaling
Perhaps you'd lose two customers but uh people are a renewable resource. If your service actually worked well you'd have an endless supply of future customers as your previous customers reproduced.
But its definitely a problem that actually doing matchmaking isn't as profitable as a chat app. Well for a publicly traded company in today's environment of short-term thinking; perhaps if it was a dividend company it would be feasible.
