Here’s the Boston tech scene, in a nutshell: Hardi Meybaum comes from Estonia, the country that gave us Skype. He moved to the Boston area in 2010, with his online product-design startup, GrabCAD. New England has a rich history in computer-aided design, with SolidWorks, Parametric Technology, and others. GrabCAD went through the Techstars accelerator program and raised about $14 million from four Boston venture firms. This week, the 50-person startup was acquired by 3D printing giant Stratasys for $100 million. Which sounds like a good outcome, but part of me wonders if GrabCAD could have been the next billion-dollar Boston company.
