Castellan procures GPU and HPC hardware the way it builds campuses: as an operating discipline. Blackwell-class GPU systems, networking fabric, and storage — sourced through established OEM and distribution relationships, benchmarked on price, and delivered to your dock or into a Castellan facility, commissioned and ready. From single-GPU trades to complete, integrated racks.
Procurement is where AI projects quietly lose months and margin: allocation queues, opaque pricing, freight and customs friction, and hardware that arrives before the site is ready — or long after. Castellan runs this layer as a professional supply-chain operation, from specification to energised racks.
Castellan trades GPUs outright — single cards and servers, volume lots, and vetted secondary-market units — and delivers complete, integrated racks: HGX baseboards, NVL72 systems, networking and storage, cabled and burned in. Every current NVIDIA data-centre generation, specified to your workload:
We work for enterprises building their first cluster, AI companies scaling an existing fleet, and institutions that need auditable, compliant procurement under Swiss or European contract law. Engagements run standalone or combined with a Castellan lease — hardware and facility delivered as one programme.
Tell us the workload, scale, and target date. We'll come back with a specified bill of materials, benchmarked pricing, and a delivery schedule you can plan against.
