About this ranking

What this page ranks

This page ranks 38 of the 50 assessed custom software development agencies in New York, United States — the ones carrying a published score — out of 56 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 New York, United States. 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 50, so the strongest award available here is top 5%.

The 6 custom software development agencies not yet assessed are listed on this page but not ranked.

A further 12 were assessed and no published evidence of their work was found, so no score is shown for them.

Placement is paid; it does not affect the ranking, cohort membership, or any agency's score. Ranking position, cohort membership and the score itself are not for sale.
