Vermietler
All-in-one rental management platform for private landlords
Vermietler launched on May 12, 2026.
What it does
We're building Vermietler because managing rental properties in Germany shouldn't require an expensive Hausverwaltung or a tangle of spreadsheets and paper folders. Most landlords with 1–50 units are stuck in one of two camps: 1) Rent tracking in Excel, tenant documents in random Dropbox folders, Nebenkostenabrechnung once a year in a panic, and receipts stuffed in a shoebox. 2) Paying 5–8% of monthly rent to a property manager for work you could do yourself—if only the tools existed.
Everything a private landlord needs to manage rental units, without paying a Verwalter. Rent, tenants, Nebenkostenabrechnung, documents. The WEG stays with your Verwalter.

We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
