This is why I think Facebook is ultimately "just" the most successful dating site/app. It matured from facilitating college hookups to sharing baby photos with family. It's the definitive place to find out that your co-worker got divorced, that your high school crush is single again, or that your ex moved across the country and got in amazing shape. The "relationship coach" is your audience of friends, family, colleagues, and acquaintances who see quite clearly how successful your romantic life is by what you (or your partner) share (or don't). I can't imagine many "matching" services/features that would make very good businesses. Unless exclusively focused on hookups, cheating, or escorts, but then naturally a harder pitch to investors.
