This can be solved by pre-registrations. I've done this before for two sites - Member of the Tribe and JSpot (both Jewish dating apps - http://JoinJspot.com ) This lets you wait until you have a certain threshold of users before you launch.

Pre-registrations for online dating are different than with other kind of consumer apps. Daters eventually stop being single. So pre-registrations are most useful if they are for a short period of time - no more than, say, eight weeks. This ensures that your profiles are accurate (single people are actually single and will become active users once you launch.)
