Mark Fosdike co-founded Datch in 2017 after spending several years as an aircraft systems design engineer at CAV aerospace. His co-founder also had experience in industrial manufacturing at Siemens and Transpower. Both are engineers, so they had a keen sense of the challenges of getting access to information and entering data while working with heavy equipment in industrial manufacturing.   Mark breaks down the key use cases, the tech stack for Datch, training the voice assistant, and much more in today's conversation. Custom voice assistants can do more than just play music and tell you the weather.
