The challenge

A content site being asked to behave like a store.

Four Sigmatic’s website had been built for education, which served the brand well early and limited it badly later — conversion efficiency was low and the structure didn’t scale with the business.

Development had also been fragmented across multiple freelancers over time, producing inconsistent code, instability, and operational inefficiency. Scaling internationally required structured CRO, better UX, and a technical foundation that could support continuous launches and new categories.

What we did

Build a system, not a project.

A structured optimization framework replaced ad-hoc improvement, and ran for years rather than weeks.

  • A structured CRO and optimization framework based on continuous testing
  • User journeys refined and UX consistency improved across the experience
  • Multiple redesigns and two rebrands supported without losing performance
  • Backend efficiency improved through system integrations and streamlined workflows
  • New product categories launched and optimized, with frequent releases supported
  • Progressive Web App capabilities implemented to improve speed and reduce bounce
  • Retention work extending experience beyond the first purchase

The results

240+ tests, and a 90% reduction in bounce rate.

A programme rather than a project — compounding across launches, redesigns, and two rebrands.

  • 240+ CRO tests executed across the ecommerce experience
  • 22 successful product launches and 3 new product categories
  • 3 full website redesigns and 2 rebrands supported
  • 28 system and app integrations improving operational efficiency
  • 90% reduction in bounce rate after performance improvements
  • +50% improvement in email conversion rates
  • Data accuracy improved by 75% for better decision-making

The takeaway

Most agencies sell projects because projects end. The compounding here came from treating optimization as something that never finishes.
