Immediate, measurable, and sustained from the moment of relaunch
The programme relaunched in October 2025. The results were immediate and have continued to strengthen across the post-relaunch period (18 Oct 2025 – 31 Mar 2026).

Beyond the headline numbers, the structural and strategic changes delivered a step-change in how the channel operates and what it contributes:
- ROAS target of £10 was exceeded, reaching 11.7x, demonstrating that efficiency and revenue scale are not in tension when the right framework is in place.
- Revenue per partner increased significantly, enabling higher absolute earnings for partners within a more efficient cost structure, a genuine win for both sides.
- With fewer partners generating clearer, more attributable data, optimisation decisions became faster and more confident.
- CSS partners were integrated into the brand’s campaign activity and product launches for the first time, a structural shift in how the channel is used that would not have been achievable with the previous partner volume.
- Closer partner relationships enabled stronger collaboration, better alignment with brand priorities, and a more agile, responsive programme.
- The channel became more predictable, more scalable, and significantly easier to manage, delivering more with materially less complexity.
Across key markets, Jan to Mar 2026 data shows continued acceleration: Partner 1 grew 26% in Germany, 48% in Sweden and 37% in Denmark. In the Netherlands, both active partners grew simultaneously (Partner B +13%, Partner C +22%), demonstrating that consolidation into the right partners drives growth, not just efficiency.
KEY TAKEAWAYS
What this demonstrates for CSS programme management
1. A budget review can be the catalyst for a step-change in strategy
What began as a period of budget constraint became the trigger for a structured CSS audit, and that audit unlocked an opportunity that routine programme management had not surfaced. Pressure creates the conditions for the most valuable strategic conversations.
2. Quality of partnership consistently outperforms breadth of coverage
Moving from up to 7 partners per region to 2, a ~70% reduction in partner volume, delivered +39% ROI improvement and +4.6% daily revenue growth. Fewer, better-managed partner relationships delivered more than a broad network at a fraction of the complexity.
3. A fair commercial baseline beats a patchwork of legacy rates
Replacing a range of CPA rates (5 to 15%) with a consistent 8% baseline was not about reducing partner investment. It created a level playing field, improved cost efficiency, and unlocked room for strategic uplifts during campaigns and key trading periods, benefiting partners and the brand equally.
4. CSS belongs in the campaign calendar, not just the always-on mix
Integrating CSS partners into product launches, campaign moments, and key trading periods, rather than running them in the background, was a fundamental part of what elevated this from a well-run channel into a strategic revenue driver. Closer partner collaboration made this possible in a way the previous setup could not support.
5. Stronger partnerships drive stronger programmes
With volume concentrated in fewer relationships, the team was able to build genuinely collaborative partnerships, with better alignment, clearer accountability, and the ability to respond faster to performance signals. The relationship quality that consolidation enabled was as important to the outcome as the structural changes themselves.
