A Startup Weekend (also known as Startupweekend or SW) is a 54-hour entrepreneurship educational competitive event, in which groups of participants form teams around ideas the Friday evening, and work during the weekend to develop a working prototype, demo, and VC presentation by Sunday evening. Startup Weekend is a hackathon-like event with a global presence. As of December 2016, it has reached 135 countries, involving over 210,000 entrepreneurs. Upon its 2015 acquisition, Startup Weekend, alongside Startup Week and StartupDigest, became one of the Techstars family of startup programs.
