Building a Recommendation Engine for an E-Commerce Giant

Services: Software Development, Analytics, User Experience · Duration: 10 months · Region: Pan-European

The Challenge

The company had a good product but was stuck. Customer acquisition costs climbed each quarter, organic growth had flatlined, and the sales team spent too much time on leads that went nowhere. They knew the product worked -- they just had no repeatable way to get it in front of the right people.

Our Approach

Research, Analysis, and Strategic Foundation

  • Ran a market analysis covering target segments, competitor positioning, and where the real growth opportunities were
  • Built customer personas from behavioral data, 20+ interviews, and third-party research
  • Mapped the full customer journey and flagged the specific steps where people dropped off or got stuck

Design, Development, and Implementation

  • Built the core platform features, prioritizing the ones users asked for most
  • Set up analytics so the team could see what was happening in real time instead of waiting for monthly reports
  • Automated the repetitive workflows that were eating 15+ hours per week
  • Connected the separate systems into one data pipeline so every team worked from the same numbers

Launch, Optimization, and Scale

  • Launched acquisition campaigns on the two channels that testing showed worked best
  • Built automated email sequences that moved prospects forward based on what they clicked and downloaded
  • Set up a referral program that rewarded existing customers for bringing in new ones
  • Created a content strategy targeting the specific search terms that potential buyers were using

Key Takeaways

  1. Three partner integrations drove more signups than six months of paid advertising. The right partnerships reach audiences you cannot buy access to.
  2. Reducing monthly churn by 2 percentage points had the same revenue impact as increasing new signups by 15%. Retention math is unforgiving.
  3. The organic content we published in month two was still generating leads eight months later. Paid campaigns stopped the moment we stopped paying for them.
  4. Shortcuts in the codebase from year one cost us three months of rework in year two. Spending an extra week on architecture early would have saved far more time.
  5. Translating the website was not enough. Each market needed different pricing anchors, different trust signals, and sometimes a completely different value proposition.
