The idea behind prototypes is to visualize your ideas. Prototypes are also essential to test and verify your product ideas. And when you finally get to the stage of transforming your ideas into something of value, prototypes are necessary to commercialize your product. Toshin is there to guide startups through this process. We aim optimize the manufacturing process with a view to the global market, from the design of prototypes, to product design for mass production and production of the end product.
