An Altrupreneur is an Entrpreneur who is focussed on creating products or services which will benefit society or others and money is a secondary concern.

Altruism as defined by Wikipedia, is the "selfless concern for the welfare of others." Or, "the opposite of selfishness."

An Entreprenur is "a person who has possession of a new enterprise, venture, or idea and assumes significant accountability for the inherent risks and the outcome."
