FOUNDER & INCUBATOR — REAL ESTATE · HOSPITALITY · AI

I build companies where real estate, hospitality and AI meet.

Five ventures, live and growing in public. Here is what each one does, how it is doing and what I am learning — and soon, a place for other founders to show their work the same way.

THESIS

Old industries, local trust, new leverage.

The same pattern runs through every venture: a fragmented, offline-heavy market where people struggle to know whom to trust — rebuilt as a lean, data-driven product.

01 · REAL ESTATE

Trust is the product

The biggest decision most people make, guided by whoever knocks first. Verified local track records change that.

02 · HOSPITALITY

Direct beats the middleman

Hosts and guests both lose to platform fees. Direct booking and curated quality bring the value back to them.

03 · AI

Leverage for a team of one

AI does the ratings, the content and the operations, so one founder can run several real-world businesses.

ABOUT

Hi, I'm Thomas.

I co-founded stayFritz in 2019 with Kerstin Langenberg: a family company in Schliersee that now runs 189 holiday homes in the Alps, on Mallorca and in Istria, with its own teams on site. Alongside it I build ventures that apply the same playbook to other markets where trust is local and the tools are old: estate agents, rent pricing for landlords, regional jobs, licensed rentals. I run them lean, with a lot of AI doing the routine work.
