Component vendors: register free in the app, publish compressors (AHRI 540 / EN 12900 maps) and coils, tag your markets. Engineers select your items in their designs; you get selection analytics and RFQ leads by email. Bulk onboarding via MCP: fit_compressor_map turns published performance tables into coefficients, import_catalog_items loads up to 100 items per call, my_leads lists your RFQs. See the vendor page.
System suppliers: publish complete branded systems from the builder — gallery placement, duty-matched suggestions under engineers' results, and a public spec page per system with live-solved performance. See the supplier page.
