Instrumental is a company started by two former Apple employees Sam Weiss and Anna Shedletsky. They built the company to help combat recall issues that can affect some companies. Due to overlooking an issue or not testing for it. The company builds hardware that gets installed onto an assembly line. This device takes pictures and shows when things begin to get put together incorrectly, or where the issues are located at. Engineers also don’t have to be at the factory to see and fix the issues. Because of the device they can stay back at the office and inspect what goes in the factory.
