Nimbis Services, Inc. was founded in 2008 by high performance computing (HPC) industry veterans  Robert Graybill and Brian Schott to act as the first nationwide brokerage clearinghouse for a broad spectrum of integrated cloud-based HPC platforms and applications. We now have a fully  integrated online technical computing marketplace comprising several stores hosting HPC and cloud modeling, simulation, and data anaysis applications packaged as software-as-a-service (SaaS) and platform-as-a-service (PaaS) products. Products are bundled and priced in configurations for entry-level through expert-level users. Products are purchased and deployed through an ecommerce interface with on-demand click-through pay-as-you-go purchasing with pre-pay and post-pay payment options and credit card or purchase order payment methods. Under development are expertise-as-a- service (EaaS) and workflow-as-a-service (WFaaS) products. Nimbis is also expanding it services through the development of similar technical computing marketplaces for regional online  manufacturing centers across the US.
