Senior Product Manager
Fabian Seibt
AI-first Product Thinking · GenAI & Platform Products
Senior Product Manager at congstar, working at the intersection of digital products, platforms and applied AI. I design and scale web and broadband products with an AI-first mindset — not as a pure AI engineer, but as a product leader who integrates GenAI and automation into discovery, delivery and operations. In parallel, I run my own product lab (Loggify), exploring GenAI-powered use cases and hands-on digital product prototyping.
