The company grew rapidly through franchising and now operates numerous offices worldwide. Keller Williams serves residential and commercial real estate markets while maintaining a luxury division. The firm provides agent training programs and technology platforms to support its associates. Keller Williams has become one of the largest real estate franchises through its profit-sharing model and expansion strategy.
