Frank Gruber, Tech Cocktail’s Co-Founder and CEO, joined Andrew Warner on Mixergy to share the story of Tech Cocktail and how he and the team have grown it from a simple mixer event to 20 city event series and online content resource for tech startup news and entrepreneurial resources. The video interview, which is over 80 minutes in total, was recorded last Friday (on the heels of SXSW) and published this week on Mixergy.
