As an entrepreneur, starting up is just the beginning but scaling up is how you change the world. This Greymatter episode is a fireside chat that took place at Greyscale, an event for tech founders hosted by Greylock Partners. Chris Yeh, the co-author of The Alliance, sits down with Reid Hoffman and John Lilly to discuss how companies go from startup to scaleup. Reid, John, and Chris taught a course at Stanford centered on this theme of hyper-growth called “Technology-enabled Blitzscaling,” and here they discuss some of the key themes from the class.
