EPC Group has been notified by G2 of placement in at least one Summer 2026 Grid Report. Specific Grid position is published when G2 reports go live; prior G2 Spring 2026 placement included Leader status in Business Intelligence Consulting — six consecutive Leader quarters (Fall 2024 through Summer 2026) with a current public 4.4/5 rating across 15 verified G2 reviews.
EPC Group publishes per-platform review counts and links to each source so buyers can verify every claim independently. EPC Group does not publish a cross-platform aggregate — differing methodologies, reviewer bases, and verification standards make weighted-average aggregation across incompatible sources misleading (see “No cross-platform aggregate rating” below). Written client testimonials are shown as attributed quotations (role + industry), not counted as reviews.

EPC Group directs buyers to verified third-party platforms (G2, Clutch, Google Business Profile) rather than publishing a self-aggregated cross-platform rating. Each platform's methodology, reviewer base, and verification standards differ; presenting a single aggregate would mislead. Verified internal client testimonials shown below are provided with explicit written permission for attribution by role and industry. Ratings on each platform are reviewed monthly against the source.
