While Keller Williams doesn't rank as the world's largest residential real estate franchise, its agent-friendly business concept sets it apart and has left a positive impression on the global real estate industry. Each Keller Williams franchise is agent-owned and -operated, commissions are split at least 70/30, and the company rewards agents through profit-sharing. Its Keller Williams University training arm also offers online resources to keep agents ahead of the curve. Dealing in both residential and commercial real estate, Keller Williams has more than 95,000 agents who operate out of 700 market centers throughout the US and Canada. The company was founded in 1983 by chairman Gary Keller and Joe Williams.
