The story of the Hlídej stavbu founder
Why did I create this platform?
“When I was renovating my own apartment, halfway through the work the construction company sent me change orders for another CZK 180,000, citing ČSN standards. As a layman, I had no way to verify them. I discovered that thousands of homeowners in the Czech Republic overpay millions of crowns every year. That is why Hlídej stavbu was born – an indicative check of the contract and budget, so you have more to go on.”
About the company
The service is operated by Simfico CZ s.r.o., IČO 03910393, Klánovická 591/1, Hloubětín, 198 00 Praha 9. It started during a personal renovation, when extra work and the works contract could not be checked as a layperson. Hlídej stavbu is not a law firm and not an expert opinion. In the beta the account and the first scan are free. Questions and further scans: info@hlidejstavbu.cz.

Frequently asked questions
Is the AI contract check a legal service?+
No. Hlídej stavbu is an information tool – it flags risky clauses and suggests wording, but it does not replace a lawyer. For unusual contracts we recommend consulting an attorney.
How much does it cost?+
This is a public beta: the account and AI audit are free, no card required. We are not taking payments yet.
What happens to my uploaded contract or budget?+
The document is processed only for the analysis and only you see the result. Details are in the privacy policy.
Can the AI check an itemized budget too?+
Yes. It compares the budget against our price database (anonymised samples and market estimates) and flags items well above typical prices. It also points out missing items that later come back as change orders.
Does it work for renovations and new builds?+
Yes, both – the modules cover the whole cycle from comparing bids through the contract and construction to warranties and claims.
Can I share the project with my site inspector or bank?+
Yes. You can share the project with read or edit roles, and every important decision is recorded.
