AI Evangelist & Product Lead AI, sipgate GmbH · Stefan Lange-Hegermann explores the question of how product development changes when code costs almost nothing anymore. Prototypes replace specifications, building replaces discussing — and judgment becomes the real bottleneck. He also works on this in practice at sipgate: as Product Lead for sipgate Flow, a platform that enables AI agents to conduct real phone calls — with phone numbers, call control, audio streams, STT and TTS via an API, without needing your own telephony infrastructure.
