Diagon

Diagon is a California-based industrial equipment sourcing company building Albus, an equipment intelligence platform for manufacturing buyers and sellers. Buyers search across millions of industrial equipment listings, compare models, specifications, pricing and availability, and connect directly with sellers; sellers publish AI-powered catalogs, reach qualified buyer demand, and see live equipment searches in real time. Diagon indexes manufacturing equipment products, suppliers and service providers, bringing hardware, services and financing into a consolidated procurement experience. Founded by a team out of Tesla, Bright Machines, Rivian and Snackpass, and backed by Anthemis under its data, tech and infrastructure thesis. Diagon publishes no public developer API today; its /api surface is an authenticated first-party application API (Clerk-based session auth) and is disallowed in robots.txt.

Diagon is profiled on the APIs.io network. Tagged areas include Company, Manufacturing, Industrial Equipment, Procurement, and Marketplace.
