Most B2B directories rank agencies by the size of their monthly sponsorship check. UpFirms was engineered from first principles to separate commercial sponsorship from organic ranking authority through our Ability to Deliver (ATD) algorithm.
Core Pillars of the ATD Score
Every agency profile is scored across verified client review quality, review volume, portfolio proof, service specialization alignment, and recency decay. Legacy reviews lose weight on a 12-month half-life so firms must continuously deliver excellence to retain top placement.
Ranking integrity is non-negotiable: no vendor can purchase a higher organic ATD score.
UpFirms Quantitative Research
ATD Scoring & Marketplace Integrity
The UpFirms Research Team conducts primary B2B vendor diligence, verified client deliverable audits, and longitudinal hourly rate benchmarking across 290+ software engineering, AI, and digital marketing taxonomies.
UpFirms Procurement Standard
Every agency ranked on UpFirms undergoes corporate registration diligence, invoiced client phone interviews, and a 12-month exponential review decay model (λ=0.05776) so rankings reflect current execution capability rather than legacy reputation.
