Poloar and STR boost revenue by 38% with VTEX FastStore

When UNIAR Group set out to scale its digital operations, it needed more than just an ecommerce platform—it needed a performance partner. Through a rigorous A/B test, UNIAR's brands Poloar and STR proved that VTEX FastStore could deliver faster, smarter, and more profitable digital experiences, driving measurable growth across every key metric.

A growing gap between vision and reality

Following a period of rapid growth, UNIAR Group sought to expand its digital operations with greater stability and scalability. Although the company was already using VTEX, it had only begun to scratch the surface of the platform's full capabilities.

To ensure long-term growth, the team evaluated alternative ecommerce platforms—looking for a solution that could unlock higher performance without compromising efficiency or customer experience.

VTEX took a consultative approach, working closely with UNIAR to guide its decision. The partnership went beyond providing technology: VTEX offered in-depth analysis, actionable recommendations, and hands-on support across conversion optimization, customer experience, and traffic strategy.

To validate its decision, UNIAR conducted a structured A/B test, comparing the VTEX FastStore stack against another platform under consideration. Both environments mirrored the real customer experience to ensure an accurate, side-by-side comparison.

The A/B test confirmed that VTEX FastStore delivered superior results across all major KPIs:

• 20% increase in conversion rate
• 10% increase in average order value
• 26% increase in order volume
• 38% increase in total revenue

FastStore also enhanced technical performance, delivering faster load times and smoother navigation, particularly on mobile.

"The results spoke for themselves. FastStore delivered the performance we needed—and VTEX's partnership made all the difference."

UNIAR highlighted that what set VTEX apart was not just the technology itself, but its strategic, consultative support. With detailed diagnostics and practical recommendations, VTEX helped translate technology into tangible business results.

That trust and partnership ultimately led UNIAR to fully migrate to VTEX FastStore.
