If men are the ones paying and women getting in for free, this is no different to the nightclub cover charge model. In both cases, men are the real customers (big spenders) and women are the product. It's the same as the social media business. Advertisers are the customers and users are the product.
Why? In traditional products, the users pay for access to the assets. Dating app men pay for access to dating app women.
Women on the other hand are often given perks for free to get them to continue to use the app, making them a cost center the app must finance to maintain.
Edit: like don’t get me wrong, if we’re going to use such cold analogies the companies definitely care about their supply, they need to be able to sell it
