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


Our value to our companies is our people. Our value to our people is our companies.

The Selling Factory (TSF) is a professional development center that offers supplemental end-to-end sales solutions, enabling our client partners to create more predictable and replicable revenue streams. Located in Gainesville, Florida next to a top 7 public university, we support businesses that seek to grow by increasing sales opportunities and B2B revenue without hiring and managing sales professionals. 

  • Step 1: We build sales teams by identifying and training qualified talent from the University of Florida to perform entry-level sales work as undergraduates and fulfill sales roles post-graduation. 

  • Step 2: Our undergraduate interns replicate the job function of Sales Development Representatives including list generation, lead qualifying, email engagement and inbox management, outbound phone outreach, and fulfillment campaigns. 

  • Step 3: We hire and manage account executives that can best represent your value proposition, and support companies looking for sales professionals to build rapport with clients and close deals.

Imagine your sales growth with an executive team seasoned in revenue growth, sales leadership, and coaching - where you didn’t have to worry about the headaches of recruitment, training and management.  

Build your sales teams and to grow your business by partnering with us.
