TinderUs is a consultancy firm that develops the profiles of Tinder app users. It suggests the best photos for clients to use, improves their profile tagline and opening lines and also gives advice on flirting.
TinderUs charges clients $50 and has had over 200 bookings, according to its founder Michael Raven.
"Our consultants are early-20s women, who work in fashion, who give guys a second opinion on their profiles, what images they think would best portrait themselves, and how they should present themselves online," he told CNBC via email. "These simple methods really do improve a profile - it's all about getting a second opinion."
