A CEO from finance × a CTO from data
Trofey is built by two people who work with numbers for a living. That is a method, not a slogan: every decision rests on a measurement against the live market.
Spent years answering one question for a business — "what does this really cost": P&L, cash flow, budgets, a team reporting to her. Now she asks that question daily of the listings market — new, used, and beyond electronics. With numbers.
Over 6 years in data: engineering, analytics, ML, infrastructure; Software Engineering degree (WSEI, Lublin). Tens of thousands of listings a day flow through his pipelines; every threshold is measured, every mistake leaves a test behind.
How we work with numbers
- Measure, don't guess. Every threshold ships after a run over live data and a read of the actual listings, not just the aggregates.
- A journal of refuted ideas. Hypotheses the data killed are recorded alongside the confirmed ones.
- Numbers honest end to end. The competitor counter runs on the same query as the seat limit; the finds history is public for everyone with a one-day delay.
- Tests that bite. Critical modules carry tests that check substance; daily data-quality checks run against the live database.
Why Ukraine
We build a Ukrainian product for the Ukrainian market: local prices, language, the official exchange rate, and a feel for how people actually buy and sell here. Poland and Romania come next, on the same mechanics.
