In Chapter 12 of 18 in his 2013 Capture Your Flag interview, entrepreneur and community builder Fabian Pfortmüller answers "Why Did You Plan a Month-Long Employee Retreat and What did the Experience Teach You?" Taking Holstee employees on a month-long destination retreat in Oaxaca, Mexico teaches Pfortmüller the value of getting out of the office and coming together as a team to bond as a family. This family culture element allows teambuilding to develop naturally through the shared experiences of going somewhere new and experiencing it together as a team. Fabian Pfortmüller is co-founder of Holstee, a socially conscious online marketplace, and Sandbox Network, a global community for young entrepreneurial people. Pfortmüller graduated from Columbia University.
