How Avant Media Ltd works — and who runs it

Who runs Avant Media

Avant Media is led by István Antal — a senior engineer with twenty years of production-software experience across investment banking, commodities trading, B2B commerce, media, and consumer services. Full career history at istvan.xyz.

The studio is single-engineer by design: clients work directly with the person who writes the code. No account managers, no handoffs, no junior on rotation.
