Zealous System has developed a machine shop marketplace where machine shops can bid on customer projects. Customers can submit a detailed parts order and request for quote (RFQ) to find a service provider.
The app is still in its early release stages, but Zealous System has fulfilled all technical requirements so far. Despite some linguistic challenges with the developers, the technical lead and project manager are strong communicators and have performed well. They provide high-quality service.
