Mars by GHC is a fast-growing men’s wellness brand in the U.S., focused on performance and backed by strong product-market fit. They run on Shopify Plus and use data to optimize every part of their funnel.
As an engineer, I’m skeptical of anything that adds friction or noise post-checkout. But Pier39 made sense from day one. The integration was clean, the offers were on-brand, and the data was transparent. Most importantly, it worked. We saw performance lift without compromising the user experience. The team was fast, responsive, and open to iteration, which is rare. Looking back, I wish we’d tested it sooner.
The Problem
CTO Niraj Gupta was looking to fix key monetization gaps, starting with a loyalty program that wasn’t driving results. Product Manager Shreya Jayant led the implementation. She prioritized brand integrity and user experience, with no tolerance for anything off-brand or disruptive.
Mars by GHC had already been showing post-purchase offers using a legacy provider, but results were weak. That’s when they tested Pier39.ai.
The Challenge
The Mars by GHC team's primary challenge was to find a partner that could deliver superior financial results. They set a clear goal for the pilot: to increase their earnings per transaction by at least 20%.
Alongside this performance goal, they had two key concerns about the integration itself:
Brand Experience: A crucial requirement was that the overall experience must perfectly match the brand’s premium look and feel to protect the customer experience.- Data Transparency: They needed a solution with clear, transparent data to easily track performance and verify discount coupon redemptions.
What We Delivered
To meet these goals, Pier39.ai’s Autonomous Ad agent picked a mix of highly relevant offers. By focusing on brands that appealed to a health-conscious male audience, such as MUD\WTR and Supermush, alongside popular brands like Disney+Hulu, the platform saw strong engagement from the very first week.
The agent also created fully branded offers and email templates to make the experience brand aligned and looking like an extension of GHC.
All performance data was available live in a shared dashboard, no hidden metrics or surprises.
The Results
The pilot was a clear success, delivering strong results across the board and exceeding the primary financial goal.
| Metric | Store |
|---|---|
 Earnings Per 100k Transactions | $52K This doubled the performance of their previous solution. |
 Engagement Rate | 8.04% This showed strong customer receptiveness to the native offers. |
 Average Reward Value | $18 This provided a meaningful incentive for customers to return and shop again. |
Next Steps
The Mars by GHC team is now exploring adding Pier39.ai offers to different email touchpoints, such as order confirmations, to increase user interaction. Both teams are watching retention closely as shoppers come back to redeem rewards.
Key Takeaways
- Native, on-brand experiences drive trust and performance
- Transparent data builds confidence and long-term partnership
- A focused pilot with clear goals → fast, measurable wins
