“Trust is the foundation of grocery ecommerce. If your basket fails once, the customer may never come back.”
— Jean-Philippe Blerot, Head of Digital, AI & Ecommerce at Carrefour Belgium
In this episode of Commerce Innovators, host Caleb Bryant sits down with Jean-Philippe Blerot (JP) from Carrefour Belgium and Kailin Noivo, President & Co-Founder of Noibu, to talk about how Carrefour is scaling digital grocery excellence across web and mobile — with a major assist from AI.
In a category where customers shop every week, small bugs have big consequences. Whether it’s a broken promotion, a slow-loading product page, or a cart that fails mid-checkout, every second of friction erodes trust.
With the help of Noibu, Carrefour is building systems that identify and prioritize the issues that matter most — before they affect revenue or loyalty.

What makes grocery ecommerce uniquely hard?
JP explains the unique complexity of online grocery:
- A typical cart has 50+ products, not just one
- Customers return weekly, not monthly or seasonally
- Pricing is dynamic, with constant promotions and updates
- Customers expect flawless speed and accuracy, or they churn
“There’s no margin for error in grocery ecommerce. If the search doesn't work, if the promo doesn't show, if an image is missing—that's it. The customer is gone."
— Jean-Philippe Blerot, Head of Digital, AI & Ecommerce at Carrefour Belgium

From guessing to knowing: Prioritizing issues that matter
Before Noibu, JP’s team relied heavily on customer complaints or internal QA to flag bugs — which was often slow, reactive, and incomplete.
Now, they use Noibu to:
- Detect issues automatically, even ones no one reports
- See which bugs impact conversion and revenue
- Fix problems faster with AI-generated insights and line-by-line diagnostics
- Use live dashboards to track performance and team output post-release
“We don’t just want to fix bugs. We want to fix the ones that are costing us the most.”
— Jean-Philippe Blerot, Head of Digital, AI & Ecommerce at Carrefour Belgium
Site speed, SEO, and invisible errors
One of the most surprising ways Carrefour has found value?
SEO performance.
Because Noibu flags performance drops and heavy image loads, the Carrefour team can optimize pages to meet Google’s standards — improving organic visibility and click-through.
“No one’s calling me to say a product image is missing. But that missing image means no one clicks the link. That’s lost revenue.”
— Jean-Philippe Blerot, Head of Digital, AI & Ecommerce at Carrefour Belgium
AI-driven quality assurance — even before go-live
Carrefour doesn’t just use Noibu in production. They’ve embedded it into pre-release staging, helping QA teams catch major bugs before they hit live customers.
One example? The morning they launched a new app, Noibu flagged a critical iOS search bug — before any users reported it.
“Noibu lets us track dev quality release by release. That’s how we improve over time.”
— Jean-Philippe Blerot, Head of Digital, AI & Ecommerce at Carrefour Belgium
Noibu's AI vision: From detection to autonomous resolution
Kailin lays out the future of ecommerce QA:
- Automated detection: Noibu flags the issue
- Root-cause diagnosis: AI finds the problem line of code
- AI-generated fix: A recommended solution is generated instantly
- Dev validation: The team approves or adjusts
- Agent-led repair (coming soon): AI writes the patch, tests it, and pushes live
“We’re going from investigation to validation. Soon, we’ll go from validation to automation.”
— Kailin Noivo, President & Cofounder of Noibu
Key takeaways for ecommerce leaders
- Grocery ecommerce is high-frequency and low-margin — trust is everything
- Bugs don’t just frustrate customers — they break SEO, promotions, and revenue
- You need to know which bugs are most costly, not just where they are
- AI can dramatically reduce time spent investigating and fixing issues
- QA shouldn’t stop at launch — and it shouldn’t all be manual
- The future is agent-powered: autonomous issue detection, diagnosis, and repair
