I love to build products people love.

Hi, I'm Till.

For 18 years I have been building tech companies and digital products as a founder and product lead. I step in when things get complex – relaunches, regulated markets, high pressure – and bring structure, speed, and AI-first workflows.

Coaching & Consulting

AI-First

I use AI daily for requirements, prototyping, test and workflow automation – and build it into products where it really helps users.

Product Management

I own the full product lifecycle – from ideation and business modelling to MVP, scaling, and relaunches.

UX & UI

I turn user research and data into clear flows and interfaces, working closely with designers from the first sketch to the release.

Web & App Development

Proven track record managing international in-house and external dev teams across SaaS, B2B, B2C web and app products.

Agile Scrum

Backlog grooming, roadmapping, user stories, refinements, and retros are my daily bread.

Coaching & Leadership

I coach Product Owners and dev teams, stepping in fast to bring structure and reliable delivery to challenging situations.
