Blog Post - Stackable Labs: The AI Experience Layer for Zendesk Messaging
On May 14, 2026, the team behind agnoStack launched Stackable Labs: the first open developer platform for building rich, branded, interactive experiences on top of Zendesk Messenger.
AI has made customer service conversations faster and more scalable than ever. It has not made them richer. Most of those conversations are still text in a chat bubble, and anything that needs an action - checking an order, changing a subscription, starting a return - becomes a link to somewhere else.
An experience layer for messaging
Stackable Labs lets brands and developers build contextual, actionable experiences on top of Zendesk's messaging and AI Agents. Its extensions pull in relevant customer data, accept input and run workflows in real time, right inside the conversation. The live demo shows what that looks like: customers tracking an order, skipping a subscription charge or answering a satisfaction survey without ever leaving the Messenger.
Extensions can be installed from the Stackable Marketplace, built without code in Stackable's AI Studio, or developed with the SDK documented at developers.stackablelabs.com. And while commerce is where we started, the same foundation works for travel, healthcare, SaaS, financial services and beyond.
In the words of our co-founder and CEO, Adam Grohs, at launch:
"For two decades, customer experience was the differentiator every company obsessed over. Then AI chat arrived, and too much of the industry quietly accepted that flatter, faster, and less human was somehow 'good enough' if it was automated. We don't think it is — and that's why we built Stackable. Messaging experiences should feel immersive, contextual, and native to the brand, not stuck inside a chat bubble. With AI woven throughout Stackable, teams can go from describing the experience they want to building it."
A sister company to agnoStack
Stackable Labs is agnoStack's sister company, and the two already work together. The Stackable Messaging Provider shipped in the agnoStack 5.41.0 release, bringing conversational commerce to Zendesk Messaging with a simpler setup for retailers on the Premium Tier and above.
Next, the same Stackable foundation is coming into agnoStack itself as Stackable Extensions: one extension model that can serve customers in the Zendesk Messenger and agents inside the agnoStack app in Zendesk.
