This is our team

Andy Kulosa
Andy Kulosa

CEO


Andy Kulosa has never taken the conventional path. As the lead singer of the punk rock band Dödelhaie, he learned early on how to generate attention — whether on stage or through guerrilla marketing for his own music‑label shop.

His drive for innovation pushed him further, ultimately leading to Microsoft Advertising honoring him as Trailblazer of the Year, an award for visionaries who redefine the boundaries of technology.

Throughout his journey, Andy has not only seen how networks operate — he has built successful, long‑lasting agency and expert networks himself. These experiences shape his perspective on genuine collaboration and modern alliances within the digital industry.

Julia Riedel

Julia has been bringing her experience as an executive assistant to senior management since 2008, with roles in start-ups, NGOs, and large corporations. She thinks ahead, organizes with foresight, and ensures — with a great deal of empathy — that our CEO and the team can stay focused on what truly matters.
Her calm, reliable manner makes her a trusted point of contact and a genuine pillar of the team — always there when it counts.
