The Full Story
Epic began working with PMX in February 2023 to transform a fragmented affiliate program into a scalable growth channel. Prior to PMX, Epic relied on multiple platforms which created operational complexity, inconsistent tracking, and limited visibility into performance. Two full-time team members were required to manage affiliates, and Epic also paid an outside agency an additional 7% of every sale to assist with management and promotion. Despite this investment, results were uneven and the company experienced meaningful coupon leakage and lost commissions.
After partnering with PMX, Epic consolidated its affiliate efforts into a single platform that streamlined recruitment, tracking, payouts, reporting, and coupon protection. This shift reduced Epic’s internal workload by approximately 60–70%, freeing up the team to focus on strategy rather than manual administration. More importantly, performance became far more consistent and measurable across the year. While Epic estimates that affiliate ROAS before PMX was roughly 2–3×, results in 2025 regularly fell in the 5.2–5.5× range including PMX fees, effectively doubling the channel’s efficiency.
PMX also materially expanded Epic’s creator network. In 2025 alone, the program grew from dozens of loosely managed affiliates to hundreds of consistently active partners, with monthly activations climbing from 104 in April to a peak of 209 in November. This broader creator base translated into stronger and more stable affiliate-driven revenue, which rose from the low $20,000s earlier in the year to as much as $59,731 in November 2025 during the Q4 surge. Even in December, revenue remained elevated at $37,667, representing a 55% increase year-over-year versus December 2024.
In addition to revenue growth, PMX helped generate significantly more creator content. September delivered 84 new affiliate posts, followed by 95 posts in November, providing Epic with a steady stream of authentic user-generated content that strengthened brand credibility and social proof.
Coupon protection became another key win for Epic. Through PMX’s blocking technology, 2,942 coupon codes were prevented from being misused, protecting 384 sessions and 78 orders and preserving $2,265 in lifetime ROI — roughly $10.50 per protected order.
Overall, Epic views the partnership with PMX as a major step forward in building a sustainable, profitable, and scalable affiliate program.
