Event Details


Marketplace startups, essentially liaisons between vendors and consumers, have been shifting business models across many industries. Investors and entrepreneurs see this as a promising model – but growing and scaling a marketplace startup isn’t easy. The complex dynamic of internal marketplace economies is difficult to define and master.

On February 26, join us and founders of some of NYC’s most successful marketplace startups at Betaworks Studios as we discuss:

  • Finding your first users and building both sides of your marketplace
  • Understanding network effects and how they apply to marketplaces
  • Developing your marketplace product and keeping your users engaged
