The Challenge
What happens when a major disruption hits your business? For luxury golf retailer Function18.com, that didn’t even stop their momentum. We helped them achieve a 42% increase in revenue and an 11% lift in ROAS in the first 5 months of 2025, reversing a period where profitability was declining.
The challenge was a classic one for large inventories: just 12% of their products were generating all the revenue, while over 90% had almost no visibility.
Our Solution
Our AI platform restructured their account, automatically sorting products into dynamic performance tiers. To match their fast-moving stock, we increased our system’s update frequency from weekly to daily, ensuring campaigns always reflected real-time inventory and performance.
The Results
The result was a powerful, largely self-managed system for the owner that delivered significant growth with minimal intervention—proving its resilience even in the face of unforeseen challenges.

- 42% increase in revenue
- 11% lift in ROAS
- Reversed declining profitability
- Self-managed system with minimal intervention
