The Taproot Foundation also offers pro bono professional aid to qualified social organizations. Their model is different from Catchafire’s in that they offer the services to nonprofit clients for free, but the project cycle is longer. The foundation works in only  five US cities, because they have found face to face meetings to be critical to project success. Project teams of five members are assembled by a professional team leader from a skills bank of many potential pro bono volunteers.  Nonprofit clients and pro bono professionals are each thoroughly vetted by professionals in the same sector, in phone interviews and in-person orientation events, before they can be recruited to a project. Once vetted and orientated, professionals are added to a Customer Relationship Management database where they await recruitment to a project. This process can take months, creating some loss of enthusiasm. The Taproot Foundation’s most popular pro bono roles are legal counsel, marketing, human resources, and financial and administrative support.
