MONTCE started in a small South Florida apartment back in 2009, a passion project turned global swim and lifestyle brand with over 60 employees and five retail stores. Swimwear remains its heartbeat, but the team, led by CEO Devin Greif alongside his sister and brand’s designer Alexandra has branched out into kids’ swim, resort wear, and dresses, now some of their best-sellers. They’ve also brought in third-party labels like Havaianas and AGOLDE, plus independent, often female-owned designers, aiming to be a curator and the go-to spot for all your vacation and lifestyle needs.

Bottle Necks & Growth Pressures

As Montce’s e-commerce took off, manual site merchandising became a bottleneck for the team. Montce’s attention to merchandising detail is core to their brand, and expanding categories meant even more collections to manage, more rules to juggle, and more pressure to convert given the rising cost of customer acquisition. The challenge was to maintain brand integrity while maximizing conversion rates to help relieve the common pressures of rising CAC’s in the industry.

Devin knew finding a solution was a priority. “We knew this was a missed opportunity but simply did not have the bandwidth,” he admits. Balancing inventory was a headache and hiding sold-out items was tedious and clashed with back-in-stock alerts that drive solid sales. Like so many DTC brands, they faced a tough call: pile on more staff or find a better way. Then, a LinkedIn post about RetentionX caught Devin’s eye. “It streamlined the shopping experience, reduced decision fatigue, and let us keep those valuable restock sign-ups,” he says. Montce dove into RX to tackle this head-on.

Implementing Smart Merchandising

Montce signed up for RX specifically for Smart Merchandising, “and that alone justified the subscription,” Devin notes. After onboarding, RX established a 2.5-month data baseline to measure performance. In June, autosorting was turned on across more than 20 accessory collections to test results.

CEO of Montce

“Our rep was not only technically sharp but also provided strategic guidance, which made implementation quick and easy. It felt less like turning on a tool and more like unlocking a new capability for our business.”

The turning point came in mid-june when autosorting began optimizing product positions using AI and Montce’s own customer data, and analyzing the performance of click-through and basket rates against the baseline collection period. “I knew it made sense from the demo, but seeing it work was the proof,” Devin said.

*Autosorting — Automatically moves products that are underperforming in current positions and receive low RX calculated scores to less prominent positions. Freeing up valuable real estate for top converting and high LTV products.

Results that Resonate

The numbers paint a clear picture across the 23 collections where it was implemented:

Metric	Uplift
Click-Through Rate (CTR)	+17.9%
Add-To-Basket Rate	+61.5%
Purchase Rate	+6.3%
Revenue Per Mille (CPM)	+96.1%

"The numbers blew us away"

— Devin admits. Who is now using RX merchandising with advanced rules to fine tune merchandising across multiple collections completely reshaping how they think about site optimization “giving us both efficiency and performance”.

Future Growth

Montce sees Smart Merchandising as more than a quick win, it’s a growth strategy. “Beyond optimizing conversion rates and site experience, the real value is surfacing true demand,” Devin explains. “When customers see the right products at the right time, it gives clearer signals for inventory planning and buying which is crucial as we grow into new categories like resort wear.” He’s confident: “RX will scale with us across markets, setting us up for smarter growth long term.” For other DTC brands stretched thin, his take is straightforward: “RX pays for itself with results.”

Conclusion

Montce’s journey with RetentionX proves how automation turns data into profitable growth. By leveraging Smart Merchandising, they overcame bandwidth limits, boosting revenue per mille by 96.1% and generating more revenue from existing traffic.
