Looking to make first steps

Hey there,
I am currently 17 years old and live in Germany.
Because of my young age I have almost no experience in things like running a bussiness or managing a start-up.
I know how to programme and even made an App.
Hoever, because the small amount of money I have I never took the step to really push the App and do the marketing and business side.
But I'm really interested on the business side of thing, so I'm looking forward to gain gaining experience on this site

Therefore I'm looking for someone who can give me an insight into their business/start-up.
And gain experience on the businnes side of a start-up.
I'm also open to just contact with somebody likemided (around my age) and exchange ideas/ concepts etc...
Please just hit me up if youre interested:

Cheers !
