The tenant layer on top of your software
Your tenants stay. The extra work does not.
mieterOS takes tenant communication off your plate - and puts recurring revenue on your portfolio, where nobody earned anything before. Your software stays. The ballast goes.
We are still building - not available for every portfolio yet.
Too much work. Too little return.
Less work
The tenth email about the same question, three programs, a PDF pile that belongs to no one. mieterOS catches the requests before they reach you.
More revenue
Someone has long been earning on the building - just not the management company. mieterOS puts recurring commissions on your portfolio, without tenants paying more.
mieterOS replaces nothing: It sits on top.
Your management software stays. The utility statement still comes out of your system - mieterOS only shows it to the tenant, to view and download. The lease is signed via mieterOS and then handed over to your existing process. The only thing actually replaced: an old tenant portal nobody uses anyway.
The knowledge base that gets smarter with every answer.
A tenant asks. The knowledge base answers when it can - around the clock, without you doing a thing.
When a new question comes through, you answer once. mieterOS checks your answer for reusability and takes it in.
Next time, the question is already answered. Every week, fewer messages reach you at all.
No guessed text snippets, but a knowledge base that learns your portfolio.
At every building, someone earns on energy and on contracts today. Rarely is it the management. mieterOS turns that around - without your tenants paying more.
Energy in the basement
Electricity and gas for the building are brokered via CLEOenergy - at basic-supply level terms. The margin that would otherwise stay with the supplier flows to you as a recurring commission. Nobody pays more.
Brokering to the tenant
Contents insurance, internet and more - brokered right where the tenant decides anyway. Every referral a commission, no work for you.
Your tenants see milo. With your logo.
milo is the app where your tenants find everything: messages, documents, the utility statement, damage reports, consumption. What management delivers comes from you - milo only makes it visible, in one place tenants open of their own accord.
- Messages
- Documents
- Statement view
- Damage report
- Consumption
Three products that already exist.
mieterOS is not a slide. The management layer is running, milo is the app for the tenant, CLEOenergy brokers the energy. What registers for early access here is not a concept, but the next portfolio that comes on board.

You manage - or you own.
Fewer requests, fewer contacts, an extra income with no added effort.
A recurring revenue line from your portfolio - no refurbishment, no extra cost for tenants.

Every management company works differently - some with modern software, others with Excel and Outlook. mieterOS doesn't judge that: it sits on top of what you already have and takes over the tenant side alone - the layer that has been missing. We are not building the next management program, we are building exactly that layer. Now is the right moment to be part of the launch from the very start. If that fits your portfolio, let us talk.
