The perfect matching service would lose 2 new users every login. No different to selling an everlasting lightbulb. The only salvation of such a perfect product would be a "de-networking effect" whereby newly-happy couples would auto-evangelize the site for bringing them together in the first place, but that wouldn't grow the site much.

The success of the "nightclub app" is that people feel they are a match only as long as they "drink", and by morning they are thirsty for more. Growth comes from the heartache of loneliness, failed relationships, and divorce. A worse product (poor matching, and stifled communication) is the actual goal of a more profitable dating app, not simply being a consequence of having more users.
