“Here,” says Fabian, turning his swivel chair around, “the magic takes place.” Magic.

As Fabian says, it doesn't sound stupid, but self-deprecating.

He is 27 years old and walks around in some kind of pajamas with pink unicorns printed on them.

He broke off his studies and is currently living again with his parents in Hamburg-Bergedorf.

That doesn't sound like a success story - but it has turned into a company worth millions.
