Who we have worked with
Your people aren't the problem. The missing system is.
Clients live in one tool, ads in another, invoices in a third, and call notes in someone's head. So follow-ups slip, hours vanish and every AI tool gives you generic answers. CustOS, the custom operating system we build around your business, fixes that.
TodayWith CustOS
Quotes go unanswered because nobody had timeIt flags it, writes the email, and you approve
The phone rings and nobody picks upIt picks up, answers and adds the appointment
You piece the numbers together at month endOne screen each morning shows what's going on
AI only knows what you paste into itIt works from your own data
Every week you wait costs you the same lost hours and the same cooling leads. The sooner you start, the sooner your system knows your business.
CustOS: the system that learns your business.
Custom-built, so you only get the parts that earn their keep. They all share one foundation: what one learns, the rest can use.

One screen each morning: what needs you, how much money came in, which client needs attention.

What is System Lab?
System Lab (also written Systemlab) is a Budapest company that brings artificial intelligence into Hungarian businesses: it finds where AI will pay off most, builds CustOS, trains the team and keeps the system running. Its founder is Bendegúz Tóth, and its website is systemlab.hu.
What is CustOS?
CustOS is the custom operating system we build around your business. Your key data comes together in one place, and AI teammates work on top of it. We set it up in your own accounts, train your team and run it for a monthly fee.
How is it different from a ChatGPT subscription?
ChatGPT sees what you paste into it, while CustOS works from your business's own data. The AI teammates see client, advertising and financial data in one place and prepare the next steps, and you approve them.
What do I get from the free assessment?
We look at your processes and data, tell you where AI will pay off most, and what to start with. You also get the assessment in writing, even if you don't continue with us.
More questions
Where is our data stored?
In your own accounts. We only ask for the access we need, and before setup we write down what data is used, by whom and for what.
What happens after launch?
We don't leave you on your own: we monitor the system, fix issues, send a monthly report with specific recommendations, and extend it as your business needs.
How long until it is up and running?
We give you the start date of the first part in writing after the assessment. The time for the full system depends on the size of the company.
Do we need a developer in the company?
No. We handle setup and operation, and we train your team to use it.
How much does it cost?
The price depends on the size of the company and the task, so we give you a specific figure at the end of the assessment. The e-book and videos are coming soon, and their planned prices are listed in the Shop.
