What works today

From offer to decision, without spreadsheets.

We use Nobar OS internally on our own portfolio. It is a young product that we are actively building.

Deal analysis

Send a listing or an address. Get a three-source valuation, a risk review and a clear verdict.

Counterparty screening

Sellers, tenants and co-investors are checked against public registers before you sign anything.

Financing and cash flow

Loans, rate fixings and liquidity across the whole portfolio in one view. Know when you will need cash, and how much.

Reports and overview

Portfolio status, deadlines and open tasks in short summaries. Only what matters, not twenty pages.

Built on Claude

Claude reasons. The database remembers. You decide.

A founder and one part-time assistant run the portfolio with Nobar OS. That is the lean model we are building for.

  1. 01Intake. Claude, through the Anthropic API, reads the listing, appraisal and registry extracts.
  2. 02Method. Every deal runs through the same written checklist and valuation steps.
  3. 03Record. Results are stored in one database, not in chat history.
  4. 04Decision. Claude proposes a verdict. A person makes the final call.
What we are adding

The whole life of a property, in one place.

From an analysis tool to a platform for everything an investor and their team handle around real estate.

Coming soon

Mortgage and bank-terms comparison built into every deal analysis.

Property sales

Preparation, valuation and sale management from listing to handover.

Insurance

An overview of policies per property, renewal reminders and offer comparison.

2 · Partner pilot A small group of partner investors and advisors, with limited access.
3 · Public launch Team access, roles, permissions and further modules.

Questions

Is Nobar OS available to the public?

Not yet. We use it internally. A limited partner pilot comes next.

Does the AI make the decision?

No. Claude prepares the analysis and proposes a verdict. A person approves it.

Which markets does it cover?

The Czech Republic first, because the methodology and public registers are built around it.

Want to be among the first?

We plan a pilot with a small group of partner investors and advisors. Tell us what you would use it for.
