Grand Prix International (GPI) is a second generation family-owned business that has been continuously in operation since 1978. We have headquarters in Springfield, MA and operate a satellite office in Hong Kong—but we work with clients and suppliers around the world.

We built our reputation manufacturing for the toy and game industry and have more recently expanded our capabilities to support other consumer sectors as well. The project management service and manufacturing acumen we offer translate seamlessly to a broad range of products and industries.

Our company maintains close relationships with our overseas partners and works directly with the factories in China and Vietnam that manufacture your products. We carefully select the right partner for every job and never bid projects out to unknown manufacturers.
