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. mieterOS manages the tenancy, not the property - and connects to your software via interfaces instead of replacing it. The utility statement still comes out of your system - mieterOS delivers it to the tenant, to view and download. The same goes for everything your software needs to reach tenants or owners: mieterOS handles the final delivery and becomes the one reliable source per tenant and owner. 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.
There is no mieterOS revenue source that is not shared with you - and no monthly fees.
Contract brokerage across the portfolio
Energy via CLEOenergy - the brand behind the mieterOS building-energy module -, later insurance as well. The commission comes from sales and acquisition costs that fall away on the supplier side in a portfolio-wide switch - not from the price tenants pay.
Brokering to the tenant
Electricity, insurance up to pet health cover, internet and TV, deposit guarantees, subscriptions and mobility - brokered right where the tenant decides anyway.
One-off commissions, paid out to you
Here the money flow reverses: mieterOS pays out to managers and landlords - for neoflat Premium placements, move-in packages or brokered one-off jobs such as the move-out cleaning.
Offer placements in the milo portal
Local partners and exclusive resident offers in the milo portal - only with residents' consent. And here too: you participate.
milo Premium
The optional resident subscription: ad-free, with perks at participating partners. A consumer subscription - whose revenue you share in as well.
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
One platform, four faces.
mieterOS manages the tenancy - and shows every party its own face, all on the same data core. This is not a slide: the management layer, milo and the energy brokerage are already running. CLEOenergy is not a product next to the platform but the brand behind its building-energy module.

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