promote + advocate + engage = Entrepreneur

Much of what outreach consists of is serving one's audiences along these lines (quoting the 'entrepreneurship education' entry at wikipedia)

Opportunities can be realized in several ways. The most popular one is through opening a new organization (e.g starting a new business). Another approach is to promote innovation or introduce new products or services or markets in existing firms. This approach is called corporate entrepreneurship or intrapreneurship, and was made popular by author Gifford Pinchot in his book of the same name. A recent approach involves creating charitable organizations (or portions of existing charities) which are designed to be self-supporting in addition to doing their good works. This is usually called social entrepreneurship or social venturing. Even a version of public sector entrepreneurship has come into being in governments, with an increased focus on innovation and customer service.
