INSIDER - Dec 6 - The Inner Circle is a selective dating app with 1.3M users, but they only approve half the number of people who apply. Anyone who posts a "duck face" mirror selfie will not be allowed to join elite dating app The Inner Circle, the company's co-founder David Vermeulen said. The selection process is not only down to photos, though - the team of seven dedicated screeners also look at age, profession, and education. The average Inner Circle user is 31, but most are between the ages of 25 and 45. Celebrities or models, however, may get approved even if they're in their early 20s.
