Don Locke spent 24 years in broadcast sales management, working to optimize inventory and revenue. Frustrated with the need for sound science-based reasoning in the field, he began researching economic principles and game theory. He poured all of his research into a massive and complex spreadsheet designed to consider the varying factors that come into play in pricing media inventory. An entrepreneur at heart, he and his wife Linda took the leap that turned that spreadsheet into software in 1999 and established ShareBuilders in the basement of their Peoria, Illinois, home.

ShareBuilders grew from a basement operation to the largest media pricing and forecasting software company in the US. In 2016, ShareBuilders purchased media CRM company Efficio Solutions, bringing additional employees working remotely across the United States. Those teams are working as one to combine the power of their legacy products into new tools and systems to benefit sales teams.

Today ShareBuilders is the most all-encompassing media sales platform on the planet. We have combined the power and intelligence at the macro level with industry-leading consultants, pricing analysts, data science, and machine learning with the micro level detail from the most integrated media-specific CRM in the world.

With the extension of their ShareBuilders family, the Locke family is proud to offer a platform to help media companies globally grow to heights that they never imagined possible.
