Hungary's first digital analytics agency

Responsible business decisions are made only on data.

So we build bespoke measurement into websites and mobile apps, and help you make sense of the data you already have.

01 — Services

What we work on

A measurement setup is never plug & play. A basic, wired-up one is usually worth little, and its business value is next to nothing.

01

Measurement audit

We review your website's tracking free of charge and give you recommendations - both for fixes and for opportunities to capitalize on.

02

Client-side setups

Full-scope measurement services for any web environment and mobile apps.

03

Server-side setups and offline conversions

Server-side tracking is the top tier of measurement. It feeds the ad platforms far more accurate data, and offline conversions bring the deals closed in your CRM back into the picture too.

04

Data analysis and visualisation

Even the best tracking is worth little if you cannot make sense of the numbers. Data is valuable, but it is easy to get lost in it - so we help you read it.

05

A/B testing and CRO

Plenty of traffic, few results? After heatmaps and behaviour analysis we run A/B tests for a measurable lift in conversion rate.

06

Automation and AI development

It often comes down to connecting systems to each other, or building something that does not exist yet.

07

Analytics consulting and training

Consulting over an online or in-person meeting, and training online or in a classroom - for small and large groups alike.

Not sure which one you need?

03 — About us

Measurement is not always a necessary evil

Sound business decisions can only be made on data. Our goal is to hand you data you can actually interpret, not just numbers on a dashboard.

Our clients range from individual businesses to PPC agencies, and most of them lack the in-house know-how for proper measurement. We deal exclusively with measurement, not campaigns - but we work closely with many PPC agencies and freelancers who know that great campaigns are built on good measurement.

DataCrew was founded in 2024 by Péter Juhász-Nagy, who has been through many agencies before, taken part in numerous international projects, and already led several teams.

    We started working with Péter when we were looking for a solution to a long-standing marketing and tracking problem that we had not managed to sort out properly for months. Péter and his team understood the problem very quickly, and thanks to the setup they built and to the Phonevert.ai system, both the measurability of our campaigns and our conversion rate improved significantly. What I especially value in the collaboration is Péter's fast response time, his flexibility and the professional attitude with which he handles and solves whatever comes up. We did not just get a system, we got a partner we can genuinely count on. I am very happy with the work we have done together so far, and we definitely want to continue it long term.

  • Freelancer

    As a PPC freelancer running a small team of subcontractors, after a while I needed someone to sort out the tracking for my larger clients on my behalf. In the DataCrew team I found exactly the right professional partner for that job. I asked for their help with client-side and server-side tracking, typically for webshops (custom builds and Shopify). Most importantly: when they handle the tracking for me, I am 100% confident that everything will be in order. They always kept the agreed deadlines and prices, and they work fast and precisely. Whether it was a bug fix or an extra request, they always responded quickly, and when a force majeure situation came up, I could count on them for the firefighting too. And whenever I wanted to understand exactly what was going on, they explained it willingly. I can only recommend them: a pleasant, reliable bunch both personally and professionally, people you can genuinely regard as partners.
