Trusted by
to calculate a 300-asset commercial portfolio with 25,000 leases
scenarios in a single stress test
portfolio computed end to end: 150+ funds, 3,000+ buildings
broken formulas. The model is data and calculation logic, not a workbook.
What your team opens every day: a monthly cash flow from contractual rent to market value, actuals and forecast in one chain, every lease with its own rules, every loan with its own conditions.
A 300-asset commercial portfolio with 25,000 leases calculates in about three seconds. Stress tests run 10,000 scenarios.
63 cash-flow lines, month by month: indexation hurdles, rent-free periods, voids, loan conditions, fund fees and exit.
Write a methodology once and run it on every asset, fund and scenario. Customise it without breaking it.
Built on more than 15 years of building financial modelling software for real estate investors and fund managers.
Most fund teams have tried at least one of them, and each hands you a new problem. Apilize is built for the part that keeps breaking: the model itself.
Enterprise planning tools
Governance, workflows and a large vendor standing behind them.
Too cumbersome for the job. Most users touch 30 % of the functionality or less, and every change waits for a consultant and a release.
Excel
Total flexibility. Any analyst can model anything, today.
Large fund consolidations and regular planning rounds: dozens of workbooks, broken links, no history and no way to tell whose version is right.
Custom AI-generated apps
Speed. A screen that looks finished in an afternoon.
No reliable foundation underneath. Hard to trust the maths, hard to exchange data with other systems and contractors, hard to keep alive once the person who prompted it moves on.
The Apilize offer
For large enterprises
Your methodology, your screens and your data flows, built on the Apilize engine and connected to the systems you already run.
For medium and smaller owners and investors
We match Apilize to your data flow and calculation logic and run it for you, fully hosted in the EU. You get the platform without having to operate it.
✕No SaaS that claims to fit everyone, or that gives you more work.
✕No chatbot that spits out isolated Excel models, or web apps that look good and become useless for regular planning or a company-wide rollout.
Apilize is a financial modelling language and calculation engine built for real estate, on more than 15 years of building financial modelling software. Keep the logic you trust in Excel today, write it once in Apilize, and let every app, report and AI agent run on it.
Data in
Excel rent rolls, appraisals, budgets and the models you use today
Accounting, property management and fund administration, connected
Price indices, market rents and interest rate curves from sources you choose
The Apilize foundation
ApilizeBuilt over 15+ yearsYour methodology written as rules, as detailed and as custom as you need. Versioned, auditable and reusable on every building, fund and scenario.
Month by month, lease by lease, deterministic. A 300-asset portfolio in about three seconds, thousands of scenarios in one stress test.
Decisions out
Planning, valuation and fund controlling, on screens built for your team
Ask in plain language. The engine does the maths, so the answer can be trusted
Your system of record, BI, reporting and Excel receive the same numbers
Show us how you calculate today: the Excel model, your indexation rules, cost allocation, fund fees and valuation method. It becomes your model in the Apilize language, and it stays flexible enough to keep changing.
Files, your own systems and trusted market data flow in, every value with its source. Nobody re-keys a rent roll again.
Your own apps, AI agents and the next systems in line call the same engine through the API. One calculation behind every screen, report and answer.
No big-bang project. We start with a free discovery workshop, write your requirements down, then build in short cycles — each one estimated in story points, approved by you and tested on your real valuation scenarios.
Free, up to one day. We walk through your valuation processes with your team. You get a scope outline and a first estimate.
Free, up to one day, led by your project owner. We walk through your valuation processes with your team: models, data sources, reports.
You getWithin a few days, a short write-up: scope outline, open questions and a first estimate in story points.
Read more about this stepOne development agreement: the requirements phase as a fixed package, and the terms for everything after it.
On the basis of the write-up we sign one development agreement. It covers the initial requirements phase as a fixed package and sets the terms for the delivery cycle: story-point rate, cycle length, hosting, IP, data protection.
You getFixed terms up front. Scope is agreed cycle by cycle, in story points.
Read more about this stepTwo tracks in parallel, your financial models and your data infrastructure, ending in a baseline specification and a prioritised backlog.
Two tracks run in parallel. Financial models: we analyse your existing valuation models (Excel, ARGUS, EstateMaster exports) and capture the requirements for the future ones. Data infrastructure: we map where your data lives today and which integrations, flows and validation rules to build.
You getA baseline specification and a prioritised backlog with story-point estimates: the overall budget range and the order in which things get built.
Read more about this stepPick, estimate in story points, approve, build, test on real scenarios. Repeat. Only approved story points are invoiced.
Each cycle: pick and refine the next backlog items with your owner, estimate them in story points (1, 2, 3, 5 or 8), approve the scope, build, then test in a test environment with your own data and models. What you learn shapes the next cycle.
You getOnly approved story points are invoiced. The specification stays current, so you always know what exists, what is in progress and what remains.
Read more about this stepYour users, your hosting choice, your data. The cycle continues for further models for as long as you need it.
Once the backlog covers your first end-to-end valuation process we go live: your users, your hosting choice, your data migrated. The cycle continues for further models and features as long as you need it.
You getFrom go-live the commercial model applies, and improvements to the engine and platform reach you continuously.
Read more about this stepSomeone who will use the application themselves, train their colleagues on it, and can give us access to the data, models and systems we need. Plus your models (Excel is fine), example reports and one IT/data contact.
Valuation, refinancing, value-add, investor updates, portfolio review, investment committee: each answered from the same model, in the time it takes to ask.
Valuation justification
A monthly cash flow over every lease, the multiplier derived from the appraisal. Reviewers check assumptions instead of formulas.
Refinancing negotiations
Test each bank’s offer against LTV and interest cover while the call is still running, and know your walk-away point.
Value-add scenarios
Lease up the vacancy, add capex and incentives, change the exit, and see the return before you commit a euro.
Investor updates
Booked history and forecast in one chain, so every report, distribution and waterfall starts from the same figures.
Portfolio review
Fund figures computed from the building models underneath, never pasted together from twelve workbooks.
Investment committee
Thousands of paths across rents, voids, rates and exit yields, on the same model the committee approves.
In 30 minutes we load a live portfolio, stress it, and show you where every number comes from. Then we talk about yours. If it fits, the free discovery workshop is the next step.
