[5] After two years in business, Keller Williams became the largest single office residential real estate firm in Austin with 72 licensed agents.

[6] In the mid-1980s, the company suffered from the United States housing bubble and began to offer profit sharing to existing and potential associates in order to retain agents and help get through the recession.

[6] Within a year, the company grew to 130 agents and began to climb back as the top real estate broker in Austin.

[6] In the early 1990s, Keller Williams expanded outside of the state of Texas, opening up its business model to franchising beginning in 1991.

[6] Keller Williams expanded at a rapid rate throughout the United States, much of which was attributed to its commission split for agents.

[9] That same year, it was attributed as the fastest growing real estate office in the entire state with 45 market centers, bringing its total nationwide agent count to over 30,000.

The same year, franchising of the company was made available in Indonesia and Southern Africa, and in 2013 expanded to Germany, Austria, Switzerland, Turkey, and the United Kingdom.

[19] The first Dubai franchise was awarded to a leadership group affiliated with IFA Hotels & Resorts which is considered the largest foreign investor in Palm Jumeirah.

[24][25][22] Keller Williams continued expansion into South America in 2018, opening franchises in Argentina, and adding to already existing locations in Colombia, Belize, Nicaragua, and Panama.

[31] Keller Williams operates a charitable arm known as KW Cares which is a nonprofit organization set up to assist both local communities as well as associates of the company and their families deal with hardships and emergencies.

[34] Beginning in 2009, Keller Williams began organizing a one-day yearly event where all associates spend a day away from the office donating their time to their local communities.
