The girl who was kidnapped aged 10 and kept locked up in a cellar by pervert Wolfgang Priklopil for eight years before escaping aged 19 is now aged 23.
Local media reported that she had invested 35,000 euros to start the company Consolea GmbH named after a cactus that grows in the Caribbean.
The company is located in the posh first district which is in the centre of Vienna and lists its activities as "promotion and marketing".
Spokesman Dusan Uzelac said: "Now that her book is on the market she wants to concentrate on her new firm and on the development and promotion of her own projects."
Local media said the projects were closely linked with Natascha's name which she didn't want to allow anyone else to take control of.
She is currently on a two-week holiday in Austria and plans to start work in the new company on her return.
Natascha has become a millionaire many times over from the sale of interviews and photographs and from the publication of her book.
