Keyzia: our review

Keyzia targets estate agents, tradespeople and diagnosticians, with a simple promise: bring together in a single interface what a construction and real estate professional would otherwise have to look for across seven different tools. The vendor, the company NEXT P, is French and based in Nantes; the product itself is still young, and its public documentation leaves several questions open.

What the platform covers

Seven building blocks make up the offer. KeyMap displays, from an address, more than 1,000 cross-referenced data points — local zoning plan (PLU), energy performance rating, transaction history, ownership — useful for an agent preparing a viewing without opening ten browser tabs. KeyChat answers a tradesperson's or agent's business questions, around the clock, in the tone of an expert assistant. KeyScore gives a property a score out of a hundred based on criteria such as insulation or heating. KeyPark tracks a property portfolio over time, KeyWatch sends personalised alerts, KeyPrompt offers a library of ready-to-use prompts, and KeyDash gives an overview of how a team is adopting these tools. An eighth module, KeyConnect, is announced as coming soon.

What's missing to trust it with your eyes closed

Two concrete gaps, even before talking about price. First, privacy: Keyzia's own data protection policy states that some data may be transferred outside the European Union, without saying which data or to where, and mentions no security certification — no ISO 27001, nor equivalent. For a tool that handles ownership and transaction data, that's a vagueness a demanding firm or agency should get cleared up before signing. Second, proof of use: none of the pages we consulted shows a client testimonial, a reference logo or a case study with figures, even though the site presents itself as the sector's "expert" assistant. The method behind the score or the valuation is likewise described only at the level of criteria (insulation, heating, environment), never down to the actual calculation. None of this proves the tool is bad; it only proves that it needs to be tested first-hand before drawing a conclusion, which is what we recommend in our training engagements with real estate professionals.

On price, a question that stays unanswered

No page on the showcase site displays an amount. The pricing grid, with a choice between monthly and annual billing and a credit system called "Keyz", only appears after creating an account on the app. A manager who wants to compare Keyzia against a competitor before spending time on a demo can't do so from the public site.

Our recommendation

Keyzia deserves a trial, not immediate adoption. The address-based database and the centralisation of trade tools answer a real need, and the vendor is no ghost site. But as long as the price stays hidden behind an account and the privacy policy admits transfers of data outside Europe without detailing them, keep the tool to a supervised trial rather than a full rollout on sensitive files.
