Agentic commerce infrastructure, built in Berlin.

We’re a team of engineers and operators shipping the agentic commerce layer Shopify brands need to be cited by ChatGPT, Perplexity, Claude and Gemini — and to run a brand-trained assistant on every surface.

Why we built it

Most Shopify catalogs are illegible to AI agents.

The next generation of commerce isn’t happening on storefronts. It’s happening inside ChatGPT, Perplexity and Claude — where shoppers ask for a product and an agent answers from whatever data is most readable.

Brands optimised for human SEO are invisible there. The fix isn’t another marketing channel — it’s infrastructure: clean structured catalog data, open agent protocols, and an intent-routing layer that doesn’t hallucinate. That’s what we build.

We’ve done this before. Our sister brand Comet Rocks Micro-store ships headless commerce infrastructure for enterprise brands — embeddable checkout, point-of-inspiration purchase surfaces, multi-channel storefronts. chatcast is the same engineering DNA, refocused on the agentic web and built for Shopify merchants directly.

How we build

Three principles, no compromises.

01
Open standards, not lock-in
MCP, A2A, UCP, schema.org, llms.txt — we ship to open protocols so your catalog is portable across every agent surface, including the ones that don't exist yet.
02
Routing, not generation
Frontier LLMs hallucinate. We classify intent in 37ms and route to a deterministic skill — search, lookup, recommendation — so the answer comes from your data, not a model's imagination.
03
Inside-out before outside-in
We audit your catalog the way an agent crawler would, then fix the gaps. Visibility comes from being readable, not from chasing rankings on someone else's surface.
