xG-Afterwork #4

On September 18, 2025, more than 60 builders from across the ecosystem gathered at Fraunhofer HHI for the fourth edition of xG-Afterwork, united by one question: What’s next?

Keynote Spotlight

• Dr.-Ing. Matheus Ribeiro-Sena (Telekom) laid out a real path toward the Quantum Internet. He shared what Telekom is building inside its labs, how they work with startups—and where the next big opportunities are.

Startup Pitches that Shaped the Night

• Roman Laabs (Sirius Computer) — Post-quantum security for RAN

• Sepideh Kouhini (Fiber Like) — Connecting small cells with light

• Martin Naydenov (swiff.ai) — AI-native cloud gaming

• Ehsan Tohidi (Fraunhofer HHI) — Network digital twins for smarter infrastructure

Real Impact

Community connections are what make our events special. Two highlights captured that perfectly.

• Kai Numssen (m4wireless) discovered a new use case in a casual conversation.

• Flybionic credits a past xG-Afterwork connection for their recent pivot and growth.
