Our company’s founder Zack Williamson has his roots in the Real Estate industry, first obtaining his Real Estate license in the state of Florida in 2004. Zack worked as an agent in Orlando and quickly learned the power of outsourcing by utilizing a call center in the Philippines to help generate leads and set appointments for showings and open houses. Within no time, they were generating more leads than their business could handle so they started selling leads and outsourcing services to other offices and then to mortgage brokers. 2 years later, in 2006 Zack jumped on a plane and went to the Philippines to open Clark Outsourcing Int’l to offer these services to companies nationwide and the rest is history!
