MetamorphGet startedMetamorph is made by DataCrew Kft., a digital analytics agency in Hungary. It exists for an unglamorous reason: we kept running into the same measurement problem at client after client, ran out of workarounds, and eventually decided the problem deserved a product of its own.
2024
Péter Juhász-Nagy founded DataCrew Kft. in 2024 and launched it as DataCrew Agency, a full-service digital analytics agency serving the Hungarian market. The work was measurement itself: tracking implementations, server-side tagging, and making sure the numbers a marketing team acts on are actually true.
The pattern
Working across a lot of accounts teaches you which problems are yours and which ones are everybody's. The one that came back most often was the conversion that never reaches an ad platform at all — the enquiry handled offline, and above all the phone call. Advertisers were buying calls and optimising for everything except them.
The first product
So we built the tool for it. Phonevert made phone-call conversions measurable and pushed them back into the ad platforms as real conversions. Along the way it picked up something we had not set out to build: it could still deliver conversions into Meta for clients whose domain Meta had restricted.
2026
That side capability turned out to be the thing clients asked about most. If the Meta data restriction was the problem people cared about most, it deserved its own product rather than a corner of a call-tracking tool. That is Metamorph: one line of code that gets a restricted site's conversions back into Events Manager, on the same pixel and the same ad account.
We are not neutral about this problem. We spent years being the ones who had to explain to a client that their campaigns had gone dark through no fault of their own, and that there was nothing in the standard toolbox to fix it. Metamorph is the tool we wanted to have in that conversation.

Founder · DataCrew Kft.
Péter has spent his career in digital analytics — building the measurement setups that agencies and advertisers make budget decisions on. He founded DataCrew Kft. in 2024, built Phonevert to close the offline-conversion gap, and started Metamorph once it was clear that Meta's data restrictions needed a product rather than a workaround.
Connect on LinkedInMetamorph was built by the people who do the tracking implementation, not by marketers describing one. That is why it behaves like a measurement tool: every relayed event is visible in the API log, request and response, so you can check our work instead of trusting it.
100 EUR per month plus VAT per pixel, 10 million relayed events per pixel included, and a 7-day free trial. No tiers, no sales call, no annual contract. Add or remove pixels yourself.

The free check tells you in about a minute whether Meta has applied data sharing restrictions to your domain — no signup, no card. If it has, the fix is one line of code and it is usually live the same day.
