Alongside with the video interview, there is also a written transcript. You don't have to share any of your own information to access it.
For Power Mathematics, Retire the Spreadsheet
Brian talked through a wide variety of topics, including why engineers and research scientists across many various industries choose PTC Mathcad and how those customers use it, the old and painful days of trying to perform complex calculations in spreadsheets, and some glimpses into the future of Mathcad.
