As an emerging field, there is no defined operating model or strategic approach. Still, philanthropreneurship marks the transition from a grant and donation model to a profit model with predefined objectives and constant focus on quantifiable results. This form of "commercial giving" demands measurable return, which is why opportunities are assessed and evaluated according to different criteria. Factors such as profitability and quantifiable performance are fixed requirements for granting support. The shift towards more business-minded professional management has also resulted in a greater focus on long-term goals. Philanthropic buying has a limited reach, which is why philanthropreneurs do not dispose of surplus funds, but tailor investments by actively leveraging their class advantages like
wealth, time, business expertise, networks, and
reputation. Philanthropreneurs include Bill and Melinda Gates, Steve Case, Pierre Omidyar and Bill Clinton. Philanthropreneurship is now supported by emerging new business models and legislation including
low-profit limited liability companies (L3Cs), created by a tax attorney experienced in entrepreneurial finance named
Marc J. Lane. ==Controversies==
