broken formulas. The model is data and calculation logic, not a workbook.

Run your portfolio like the business it is.

Five things every real estate investor wants to know, every day. Apilize answers all of them from the same model, so nobody has to reconcile five versions of the truth.

Value

Know what every asset is worth today and at exit, and why. Valuations you can defend to auditors and buyers.

For valuers and fund managers

Income

See where next year’s NOI comes from, lease by lease, and act on vacancies and indexation the day they appear.

For asset managers

Capital

Walk into every refinancing knowing your covenant headroom under each term sheet on the table.

For finance and treasury

Risk

Stress the investment thesis across thousands of scenarios before the committee, or the market, does it for you.

For investment committees

Trust

One number for investors, auditors and regulators. Every value carries its source, author and time.

For fund administration and IR

Designed to support your money decisions.

The decisions on your calendar, each answered from the same model, in the time it takes to ask.

Valuation justification

What is it worth, and why?

A monthly cash flow over every lease, the multiplier derived from the appraisal. Reviewers check assumptions instead of formulas.

Can the building carry 5.5 %?

Test each bank’s offer against LTV and interest cover while the call is still running, and know your walk-away point.

What is the upside worth?

Lease up the vacancy, add capex and incentives, change the exit, and see the return before you commit a euro.

Why Apilize

Why not a planning suite, Excel or an AI-built app?

Most fund teams have tried at least one of them. Each solves part of the problem and hands you a new one.

Heavy enterprise planning tools

Good at

Governance, workflows and a large vendor standing behind them.

Where it breaks

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

Good at

Total flexibility. Any analyst can model anything, today.

Where it breaks

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

Good at

Speed. A screen that looks finished in an afternoon.

Where it breaks

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

Your logic, on a foundation that lasts.

For large enterprises

We build your apps on our foundation. You own them.

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

Customised to you, hosted on our secure EU cloud.

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.
