Hi, I’m Till.
I have been building tech companies and digital products for the past 18 years, bringing deep expertise in entrepreneurship, product management, AI-driven workflows, as well as coaching and leading international teams from early-stage MVPs to complex, high-pressure relaunches.
Coaching & Consulting
Product Management
I own the full product lifecycle – from ideation and business modelling to MVP, scaling, and relaunches.
Agile Scrum
Backlog grooming, roadmapping, user stories, refinements, and retros are my daily bread.
App Development
Proven track record managing international in-house and external dev teams across SaaS, B2B, B2C web and app products.
AI-Driven
I use AI daily across the product lifecycle and build it directly into products for smarter, faster workflows.
UX & UI
I am a passionate product person with a design thinking, lean, and agile mindset.
Coaching & Leadership
I coach Product Owners and dev teams, stepping in fast to bring structure and reliable delivery to challenging situations.
