What we do
Antczak Enterprise International combines product design, financial thinking and day-to-day operations. The company owns products end-to-end instead of acting as an agency.
Product ownership
Full responsibility for concept, design, development and long-term maintenance of digital products, with a focus on clear, calm UX.
From prototype to live app
Health & performance tools
Building simple, evidence-informed tools that help track water, training, steps, sleep and habits without unnecessary noise.
Everyday usability first
Data & finance aware
Product decisions are grounded in numbers: user behaviour, cost structures and long-term sustainability, not just short-term hype.
Built on financial discipline
