Our mission is to provide a high-energy selling environment where students learn, entrepreneurs grow, and companies thrive.

Learning + Doing

Everyday, we inspire tomorrow's leaders by supporting the growth of today's companies.

The Selling Factory is a professional training center for students, entrepreneurs and companies alike. The Selling Factory has built a LEARNING + DOING selling environment.  We coach students, entrepreneurs, and sales professionals on the skills necessary to be successful.  Active selling takes place on the TSF Sales Floor, where our teams make outbound calls, prospect for business, set sales meetings, and close deals.  Our selling-focused environment is what makes us different, and what produces long-lasting results for our teams and companies.

After several years of mentoring and coaching companies in Gainesville, we found that most companies do not have the knowledge or experience to build and maintain a high-performing selling environment. So we created the space ourselves.

We provide four main services to students, entrepreneurs, and companies.




The Selling Factory has helped us on multiple projects to research potential leads and make outbound calls to set appointments. They’ve done a fantastic job working through the tasks we’ve asked with detail and accountability. Brad is a joy to work with; he has always been responsive and thoughtful about managing his team to provide a great experience for us. Any questions we’ve had have been promptly resolved to our satisfaction. We continue to think of TSF when we need additional resources.
