  • Subsidies in regulated markets (the traditional model)
  • B2G – Business to Government
  • B2B – Business to Business

Some companies make products, other deliver services or both.

All companies have a way of engaging its constituents, stakeholders and customers, be it by:

  • auctions
  • brokerage
  • advertising
  • infomediary
  • merchant
  • manufacturer
  • subscription
  • affiliate
  • utility
  • community
