WARSAW
A data analyst in Warsaw, on your side of the table.
Not an agency. One data scientist, a registered Warsaw company, and work you can check.
Zastron Labs is a one-person data studio in Warsaw. I build honest websites, custom business systems and data analysis for small firms, from 690 zł a month, with no setup fee. The company is registered in Poland (KRS 0001250566), I work in Polish and English, and everything I build for you, code, content and domain, is yours. Warsaw clients get me in person; the rest of Poland gets me remotely.
WHAT I DO
Three things, done properly.
-
A website kept honest
Hand-built, fast, secure, and never left to rot. Hosting, domain and updates handled, with a plain-language monthly note on your numbers. From 690 zł a month.
-
A system built for your day
One custom tool that fits how your business actually runs: booking with automatic reminders, a client list that never forgets a renewal, a quote calculator. See how it works.
-
Analysis you can act on
Your numbers, cleaned and answered in plain words, with every figure traceable to its source. Forecasts with their honesty stated, and tests before you spend. The method.
WHY LOCAL
What a Warsaw business gets from a Warsaw analyst.
-
A person, in person
We can sit down over coffee in Warsaw and look at your numbers together. The person you meet is the person who does the work.
-
A Polish company, a Polish invoice
Zastron Labs sp. z o.o., registered in Warsaw, invoices in złoty. No exchange rates, no foreign contracts, no mystery.
-
Your language, both of them
Work delivered in Polish, English, or both. Useful when your customers speak one and your suppliers the other.
-
GDPR done seriously
Your customers' data is handled under EU law, and I will tell you plainly what we can and cannot do with it.
PROOF
Check my work before you email me.
My own product, Cario, is built on public data: the Polish national vehicle registry, UK inspection records, and part prices researched across Polish shops. Every number on the live dashboard traces back to its source, and the case study shows the working. That is the standard your project gets.
QUESTIONS
Asked before, answered honestly.
-
How much does a data analyst cost in Warsaw?
At Zastron Labs a website kept honest costs 690 zł a month. A site plus one custom system, like booking with automatic reminders, costs 1 490 zł a month. A data scientist on retainer, with a monthly analysis of your numbers, starts at 3 490 zł a month. One-off projects get a fixed written quote. No setup fee, month to month, prices exclude VAT.
-
Do you only work with businesses in Warsaw?
No. The company is registered in Warsaw and I meet Warsaw clients in person, but I work with businesses across Poland remotely, and with international clients in English.
-
Do you work in Polish or English?
Both. Everything I deliver, from the website copy to the monthly analysis, can be in Polish, English, or both. This site itself runs in both languages.
-
What kind of businesses do you help?
Small firms where bookings, clients and repeat visits drive the money: salons, clinics, workshops, studios and local services. If I look at your situation and honestly think data will not move your numbers, I will say so before you pay anything.
