Direct Implementation & Optimization
KETUPA works directly with the merchant to implement or improve the AI Shopping Agent around its products, business requirements, and important buying journeys.
ABOUT KETUPA
The specialist implementation, optimization, and reliability partner behind reliable AI shopping experiences.
AI Shopping Agent platforms provide powerful Agents, data connections, workflows, analytics, and implementation controls. But every merchant still has its own product truth, category complexity, customer needs, business rules, priorities, and exceptions.
KETUPA provides the merchant- and category-specific delivery required to turn those platform capabilities into reliable real-world shopping experiences. We work within the Agent and commerce stack already in place—establishing the required shopping behavior, testing complete journeys, implementing accepted optimizations, verifying the results, and maintaining critical behavior over time.
HOW WE WORK
Start directly, work collaboratively, or build an ongoing optimization partnership.
Collaborative Implementation & Optimization
KETUPA works alongside the merchant’s existing AI platform, agency, or internal teams—owning or co-owning the merchant-specific Shopping Agent work while using the existing stack and native platform capabilities.
Ongoing Optimization & Assurance Partnership
After launch or an initial optimization, KETUPA can continue working with the merchant to improve important buying journeys, expand into additional categories, and maintain merchant- and category-specific quality as products, policies, and AI systems change.
LEADERSHIP
A specialist team focused on AI Shopping Agent behavior—backed by senior Amazon and Microsoft AI shopping experience.
KETUPA combines focused work on how Shopping Agents guide real purchase decisions with senior experience building large-scale search, ranking, retrieval, conversational AI, agentic systems, and production software.

BEYOND THE FOUNDING TEAM
Specialists across the full Agent improvement cycle.
KETUPA also works with specialists across AI shopping, evaluation and reliability, implementation, product quality, customer success, UX, QA, and engineering.The team works as one delivery unit—from understanding the merchant and category to improving the Agent, validating the change, and keeping important behavior reliable over time.WHY KETUPA EXISTS
A capable Agent can know the product and still guide the shopper incorrectly.
The hard part is often not whether the Agent can retrieve the right fact.
It is whether the right shopper requirement, product condition, merchant rule, or exception actually changes what the Agent recommends, ranks, claims, asks, shows, and does next.
That behavior can work in one response and break under different shopper wording, a different product card, or as shopper requirements change during the conversation.
KETUPA exists to make merchant- and category-specific Shopping Agent behavior explicit, implementable, measurable, and reliable.
WHAT KETUPA IS BUILDING
The end-to-end optimization and assurance system for merchant-specific AI Shopping Agent behavior.
KETUPA is building a repeatable system that turns merchant and category requirements into implemented and verified Agent behavior. It connects business-approved behavior, category-specific evaluation, targeted implementation, before-and-after verification, and retained regression coverage—working through the Agent and commerce stack already in place.
Built for merchants and AI commerce platforms that need important shopping journeys to work correctly for their specific products, categories, policies, and customers.
FOR PLATFORM PARTNERS
Merchant-specific delivery that extends the value of your platform.
KETUPA helps platform customers translate strong platform capabilities into shopping experiences that work for their specific products, categories, policies, and customers.
We can support merchant onboarding, category-specific configuration, implementation, optimization, validation, and ongoing reliability. KETUPA can work alongside your delivery team, co-deliver with your agency partners, or lead the merchant-specific Shopping Agent optimization workstream.
We work through the capabilities and controls already available in your platform. KETUPA does not replace the Agent platform—we help joint customers realize more value from it.
