Who runs investment decisions at TWENTYTHREE ADVISORY?

Co-founders John Sjölander and Andreas Feuk jointly manage the firm's investment decisions. Sjölander brings operational experience from e-commerce and digital growth companies, while Feuk contributes a background in banking and capital deployment. Their combined oversight allows the firm to blend principal investing with hands-on advisory support for portfolio companies.

Does TWENTYTHREE ADVISORY invest in fund commitments or only direct deals?

The firm's capital is deployed entirely through direct deals into private companies. There is no public record of fund-of-funds commitments or LP stakes in external venture capital funds. This direct-only posture supports the co-founders' thesis that concentrated, hands-on investing generates better alignment and better outcomes.

Where does TWENTYTHREE ADVISORY invest geographically?

The investment mandate covers Europe, with a concentration in the Nordics, the United Kingdom, and Germany. The firm's Stockholm headquarters anchors its local network, but it pursues opportunities across the continent where consumer technology and internet brands are scaling.
