The Tiger Challenge is a co-curricular, design thinking program in Princeton University's Keller Center. In small teams, students work with partner communities to develop lasting innovations and the joint-capacity to address seemingly intractable societal issues, such as affordable housing and adolescent mental health.

This is not a competition or course; every Tiger Challenge team is highly supported throughout, receiving the training, mentorship, space and resources necessary to do this crucial work well.

Vision and Mission

It is the vision of the Tiger Challenge to equip Princeton students and program partners to tackle important & complex challenges, by inspiring curiosity, creativity, compassion, and the courage to take action.

We seek to create a world-class, world-serving program with three equally important missions: to build sustainable community impact; to foster student and partner growth; and to create a great experience for all involved. 


While Tiger Challenge teams work on impactful projects of all kinds (from education and health to social justice and the environment), we all use design thinking as our primary approach to the work. Design thinking has three layers: process, tools, and mindsets.

Learn more about this methodology grounded in empathy, creativity, collaboration and open-mindedness.


There are two approximate timelines for the Tiger Challenge. Some teams begin with a full-time 10-week summer immersion, and continue through at least the following academic year. Other teams begin in October and work for at least two academic years (without a summer commitment). 

One of our guiding principals is end-to-no-end support. Teams are encouraged to continue in the Tiger Challenge beyond the outlines above. We also support teams through "exit" including hand-offs to partner organizations or the founding of social ventures in the Keller Center's eLab program.  

Tiger Challenge Today

To-date, 125 Tiger Challenge participants have tackled 22 projects: eleven in the community and eleven on campus. Each team consists of three-to-six students of diverse class years, majors, and backgrounds. Overall, students from 25 different majors have participated. 

While each team tackles a different project, the Tiger Challenge has a one-firm ethos. We share a space, a community, and a drive to co-create a better world.
