Who EstateMate is built for.
Owners with a property manager
Your property manager handles the day-to-day. You keep the full picture and stay in control.
- See at a glance which rents are below market, which leases are expiring and where the upside is.
- For every property: expected rent next to debt service, and what is left once costs and financing are paid.
- Leases and loan agreements digitised and analysed, with every figure linked to its source document.
Family offices
Multiple entities, multiple people, one set of numbers.
- The portfolio broken down by entity and property, available whenever you need it, every figure traceable.
- Role-based access: family members, directors and staff work in the same system, each with the permissions their role needs.
- Reports for the bank and for shareholders from the same data: rent roll as at any date, loan schedule and income statement, as PDF or Excel.
Asset managers and larger portfolios
For portfolios run by a team. We are building this out on our own portfolio, together with the first customers of this size.
- Expiries, stepped rents and rent increase potential across every property, totalled, in one list.
- Ask questions of the whole portfolio: every flat under 7 euros per square metre, one filter, one click.
- Role-based access for the whole team. Whatever else an in-house team needs, we build with you.
What EstateMate does differently
The same work in four worlds.
| EstateMate | Excel and folders | DIY AI tools | Manager software | |
|---|---|---|---|---|
| Rent overview pull the rent roll · check actual against target · see vacancies | Ready: actual and target, with the document | Kept by hand, quickly stale | Re-check every result, different tomorrow | Request and wait |
| Rent potential track rent steps and deadlines · check headroom against the local index · follow up on increases | Due steps and headroom, with the contract | Formulas and deadlines in your head | Plausible, but checked by hand | Runs only on reminders |
| Payments and liquidity check incoming rents · see outgoings against balances · know whether a building is paying its way | In and out per building, continuously | Re-typing statements, duplicates surface late | One-off only, no ongoing monitoring | Your own accounts stay out of view |
| Financing fixed-rate periods in view · remaining debt per date · which loan to pay down first | Fixed rates, remaining debt, scenarios on your numbers | Own spreadsheet, only as good as its upkeep | "Looks right" is not enough for the bank | Loans usually missing entirely |
| Documents and traceability assemble the bank's package · find the document behind a number | Every number leads back to its source | Search, request, hope | Source not traceable afterwards | Piece by piece, on request |
| Reports and packages report for the bank or the accountant · status per building · hand over as a fixed snapshot | On demand, as a fixed snapshot | Copied together fresh every time | A different format every time | Manager's view, barely adjustable |
| The honest limit | Plugs into your existing software - the modern way to run your portfolio. | Costs nothing and is often enough for two or three buildings. | Fast and surprisingly helpful for one-off questions in between. | Built for the manager's day-to-day, and strong at it. |
Real estate and operational expertise, under one team.
We run a portfolio of our own and have built organisations of thousands of people. EstateMate is our own tool, and we bring it into your office.
Ari Birnbaum

Ari runs his family's family office in Munich: a portfolio of over a thousand units, in-house management, a team of five. Before that, two years in tax advisory.
No software could show his portfolio the way an owner sees it: cash flow, financing, value per property. So he built it himself. Since 2025 he has run his entire portfolio on EstateMate.
