Description

Flat Capital AB is an investment company founded in 2013 by Nina and Sebastian Siemiatkowski. The firm specializes in making long-term, passive investments in pioneering, unlisted growth companies led by dedicated entrepreneurs worldwide.

The company's core philosophy is a hands-off approach, offering patient capital and trusting founders to build long-term value.
