Extension traction 300+ installs

Problem

Romanian shoppers compare the same product across many retailers, but prices, stock, discounts, and product matches are hard to evaluate quickly and confidently.

System

Pretzi combines SEO-facing product/store/category pages, browser extension overlays, merchant coverage, price tracking, alerts, conservative matching, and affiliate routing into one comparison workflow.

My Role

I shaped the product direction, extension UX, matching rules, merchant coverage, privacy positioning, tracking flows, monetization setup, and launch packaging.

Scope & Guardrails

Pretzi is strongest where coverage, accuracy, privacy, distribution, and monetization have to stay aligned.

Owned Product direction, extension UX, matching rules, merchant coverage, tracking flows, privacy positioning, and affiliate setup.
Guardrail Matching is conservative, methodology is public, and affiliate routing is separated from ranking logic.
Trade-off Coverage growth is balanced against data quality, supported-store behavior, extension permissions, and user trust.

Product Evidence

The proof leads with product-data operations, merchant coverage, and privacy decisions. Extension installs are useful secondary traction, not the core positioning.

Monetization Affiliate routing is separated from ranking and comparison logic.
