Can you please tell me how to convert attention into money? Genuine question, since it seems like the business model of a lot of B2C startups out there.
i consider membership, subscription, pro features, in app purchases and premium features to be almost equal. Same for ads and sponsorships. In other words: that leaves you with ads, premium featues or selling the data. Which can be quite hard to sell, depending on your audience (I consider Twitter a good example).
