What this page ranks
This page ranks 26 of the 28 assessed custom software development agencies in Warsaw, Mazovia — the ones carrying a published score — out of 28 listed.
The score measures how well an agency documents its own work in public — named clients, quantified outcomes, and whether those outcomes are attributed to the agency rather than described as the client's own results. It does not measure client satisfaction, price, or availability.
Cohorts and awards
Agencies are compared within a cohort — here, Custom Software Development in Warsaw, Mazovia. A cohort must be large enough to express the band being awarded: at least 8 assessed agencies for a top 25% award, 20 for top 10%, 40 for top 5%, and 300 for top 1%. This one holds 28, so the strongest award available here is top 10%.
The 1 custom software development agency not yet assessed is listed on this page but not ranked.

Paid placement
