赛扶，全名国际大学生企业家联盟（Students In Free Enterprises，简称SIFE），是一个国际性的非营利组织，总部位于美国密苏里州斯普林菲尔德。其前身为「美国领导力研究协会」。主要是通过课外实践，创建学生、学术界与商业界领袖的国际教育学习网络。

赛扶创立的目标是以某个行业商业改良或者开发新项目的模式来帮助社会上的某个群体生活质量提高，商业运营规范化，同时使学生在做立项、进展项目的过程中能够对于商业和经济有更深入的了解。由于该项目对于学生的知识背景，尤其是经济方面的知识要求比较高，所以赛扶在各个地区的分部主要都在各地区著名的高等学府中。在中国，像清华大学、北京大学等学校已经成立了各自的赛扶团队，并且取得了一定的成果。

ENACTUS, known before October 2012 as Students In Free Enterprise (SIFE), is an international non-profit organization that works with leaders in business and higher education to mobilize university students to make a difference in their communities while developing the skills to become socially responsible business leaders. Participating students form teams on their university campuses and apply business concepts to develop outreach projects that improve the quality of life and standard of living for people in need. An annual series of regional and national competitions provides a forum for teams to present the results of their projects, and to be evaluated by business leaders serving as judges. National champion teams advance to the ENACTUS World Cup. In addition to the community aspect of the program, ENACTUS leadership and career initiatives create opportunities for learning and exchange among the participants as well as the placement of students and alumni with companies in search of emerging talent.
