How we built this page

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.

  • Verified third-party platforms: G2 (4.4/5 across 15 reviews; G2 Leader in Business Intelligence Consulting for seven consecutive quarterly reports through Fall 2026), Clutch (3.8/5 across 4 reviews), and Google Business Profile listings across six verified office locations. Each platform's public profile is linked below — buyers can verify per-platform ratings directly.
  • Internal client testimonials: written quotations from current and past clients, provided with explicit written permission for attribution by role + industry. Selected representative quotes appear below.
  • Verification: G2 and Clutch require reviewer login and employment verification. EPC Group does not pay, discount, or otherwise incentivize reviews on any platform.
  • Refresh cadence: External platform ratings reviewed monthly against source; internal testimonial library updated quarterly.
  • No cross-platform aggregate rating: EPC Group deliberately does not publish a weighted-average cross-platform rating. Each platform's methodology, reviewer base, and verification standards differ; presenting a single “aggregate” across incompatible sources would mislead. Buyers should evaluate each platform's public profile individually.
