PrimeCo — technology and design studio

Point a camera at a comic. Get back the book, its market value, and what to do with it next.

Collectors and shops run on spreadsheets, then sell across a dozen marketplaces that agree on nothing. Stash replaces both: a catalog of more than a million priced issues, Anthropic's vision models recognizing a book from its cover, and valuations that resolve grade by grade.

One system carries all of it. A single application serves the web product, the public API, and an OAuth-secured MCP server — so Claude and ChatGPT can read and write a collection directly, with the owner's permission. The iOS app shares that same backend rather than duplicating it. Scan on the phone; it is already on the desktop.

Selling is where collectors lose their time, so the catalog pushes outward: eBay through its API, plus Facebook, Instagram, Whatnot, Heritage and a dozen more channels. Barcode labels and point-of-sale for brick-and-mortar shops are in progress.

Agentic AI, made legible at the scale of an enterprise platform.

The name stays behind the contract, as these engagements usually do. The work does not: software that acts on its own is only adoptable if people can tell what it is about to do. We work at the platform layer on exactly that — the patterns governing how an agent introduces itself, asks permission, shows its reasoning, and hands control back.

Consistency at this altitude is not cosmetic. A pattern set once in the design system arrives in every product built on the platform — which is how thousands of teams ship intelligence that behaves the same way twice.
