Ask HN: Can I turn my side project into a business?

Congrats, it looks good and translated well into English. A platform for independents to upload their event and take bookings would be good. These types of events attract a local market/patronage and so that's where your market is for each User (Independent). So in terms of business models you could open your platform for free to the User (independent theatre/event/act) to add their event and take bookings and they could in turn charge local restaurants, businesses etc to advertise through them to their local market; your platform takes a commission of the advertising revenue. Some functional outcomes your app should offer Users; 1) advertise their event and take bookings (done); 2) demonstrate to local businesses the demographics of audience they are attracting to their event (you can capture this on booking-no big deal) 3) provide simple digital marketing tools for the User to promote the event and their advertisers (off the shelf integrations are fine) and 3) collect advertising revenue from participating customers. How all this comes together is a considerable undertaking but you already have a working MVP you just need to work with Users (independents) and Customers (advertises/businesses) to get the product right for both and a businesses model that supports growth. Do that first before building any scale into your product. Good luck and congrats again.
