How Dance4Life is growing their impact with social franchising

Business models for good are business models for companies that want to create impact. With the use of one of these models, you are contributing to a solution of a social problem in the core of your business. For commercial companies, like TOMS, who was one of the first to use the business model “one for one”; for foundations who want to grow, like Dance4Life, who laid the foundation for explosive growth with their business model “social franchising”; and for social entrepreneurs, like Peerby, who enables neighbours to borrow or rent things from each other with their multisided platform.

I experienced Marjan de Jong as a manager that truly knows how to empower her team members. Leadning and guiding you in a way that gets the best out of you, she knows how to intrinsically motivate. Furthermore she is a strong strategist who never looses sight of the overall picture and objectives set, she knows well how to influence and engage the different stakeholders involved to go along in the same direction. Marjan knows how to deliver under pressure, keeps her cool, sets the right priorities and act accordingly. Her enthusiasm and energy is infectious!
