We believe great support shouldn't be expensive
Retenza started with a simple observation: most Shopify support tickets ask the same questions. We built an AI that answers them — instantly, accurately, and in any language.

Make world-class customer support accessible to every Shopify store
Large brands have entire support departments. Small and mid-sized Shopify stores compete on the same product quality — but not always on support speed. Retenza levels the playing field.
Our vision: a world where every customer gets a helpful, accurate reply within seconds — regardless of the size of the store they're shopping from.
Speed is a feature
A customer waiting 4 hours for a reply is a customer considering a refund. We build every feature with latency as a first-class concern.
AI that respects humans
Our AI assists your team — it never replaces judgement. Low-confidence replies always land in a human inbox first.
Privacy by design
Multi-tenant isolation, encrypted at rest, GDPR-compliant. Your customers' data is yours — we're just the processor.
Truly global
Your customers write in French, Polish, Arabic, Spanish. We reply in their language, automatically, from day one.
Built by people who understand e-commerce
Our team has built, scaled, and sold Shopify stores. We know the pain from the inside.
