The NVIDIA Partner Network is an invitation-only sell-with program for partners whose primary business model is value-added reselling, integrating solutions, designing or manufacturing systems, providing hosted services, consulting, or servicing NVIDIA products and solutions.
ISVs who participate in NPN are industry-specific vendors with validated solutions who partner with NVIDIA solution providers to co-sell and co-market to drive joint engagement. (Please note that the NPN and Connect programs are for different partner types, so you can only be in one or the other.)
