When a tech startup finishes making prototypes and creates a cool new app, the leaders think about the best ways to money from it. They look at costs, how much they want to earn in the long run, what other similar services are doing to attract customers, and how much their target users to pay for certain features. They might let people use it for free or at a lower cost at first to get more users and attention, and then decide on the right amount to for subscriptions. The price for different subscription levels should match what makes their app special for different types of customers, considering their hobbies, how much money they have to spend, and what other apps can't give them. Besides selling the app directly, they can also make profits by letting big companies use it or by sharing user data with advertisers. This helps keep the app free for regular users. Like any pricing plan, they need to adjusting it based on how people are using the app, to find a good balance between and viable profit margins.
