Why teams leave Fast Simon
These are the switching triggers we hear from Shopify teams, mapped to outcomes after migrating to Nimstrata.
Relevance doesn't handle catalog complexity
Standard keyword matching breaks down with complex product attributes, variants, and unique items. Vertex AI learns from real shopper behavior to surface the right products.
Custom integration costs are hard to justify
Building and maintaining a direct Google Cloud integration requires months of engineering. Retail Cloud Connect handles the infrastructure so your team ships faster.
Search results don't convert
If shoppers can't find what they're looking for, they bounce. Better relevance means higher conversion from search — Cotopaxi proved a 44.78% lift.
Decision framework: relevance quality first
Start with search quality and conversion impact. Once relevance is validated, compare implementation speed and total cost to operate.
