Overview
SPARTOO.NET is one of Europe's largest online fashion retailers, offering more than 39,000 pairs of shoes alongside clothing, bags, and accessories from 484+ brands.
The platform serves customers across multiple European markets in several languages, with dedicated segments for women, men, children, luxury, sport, and eco-friendly fashion.
iVega partnered with Spartoo to design and deploy an AI layer across the customer journey, helping a massive catalog feel more personal while supporting discovery, fit guidance, and support efficiency.
The Challenge
Growth was no longer a traffic problem. It was a relevance problem.
Spartoo needed to help shoppers move through scale with more precision: finding relevant products faster, choosing size with confidence, and getting routine answers without slowing human teams.
Catalog depth versus discoverability
With tens of thousands of SKUs across brands, categories, and segments, shoppers needed a faster path from broad search to relevant products.
Size and fit uncertainty
Footwear returns are often driven by inconsistent brand sizing. Spartoo needed smarter guidance to help shoppers choose the right size first.
Generic recommendations
Rule-based suggestions did not capture style affinity, seasonality, occasion, or cross-category intent across the customer journey.
Multi-market support load
Routine multilingual queries around orders, returns, size guidance, availability, and delivery were absorbing customer service capacity.
Our Solution
iVega designed and delivered an integrated AI stack built around four production modules, all tied into Spartoo's existing commerce and data infrastructure.
Personalized Recommendation Engine
A hybrid model combining collaborative filtering with content signals including brand affinity, color palette, style tags, price band, and season.
AI Size and Fit Predictor
A model trained on historical purchase and return data to understand per-brand sizing behavior and recommend size with confidence scoring.
Intelligent Multilingual Search
Semantic search that understands intent, synonyms, misspellings, and natural queries such as comfortable shoes for walking all day.
AI Customer Support Assistant
A multilingual assistant for high-volume routine support, with clean handoff to human agents when cases require deeper attention.
The full stack was delivered as modular services so Spartoo's internal team could iterate on each component independently, with monitoring, A/B testing, and a feedback loop into model retraining built in from day one.
Impact
Significant double-digit conversion uplift on personalized surfaces versus the control experience.
Meaningful average order value increase through relevant cross-category recommendations.
Notable reduction in size-related returns where the fit predictor was active.
A large share of routine support queries resolved by the AI assistant.
Lower search exit rate, with shoppers finding products in fewer clicks.
What It Enabled
A production AI foundation for commerce growth.
Beyond immediate funnel and support improvements, the engagement gave Spartoo a reusable AI foundation that can extend into demand forecasting, dynamic merchandising, and inventory planning.
The result is not a single feature layer. It is an intelligence layer designed to help a large catalog become easier to navigate, easier to personalize, and easier to evolve.
