Founder and CEO at Proven
John is one of the founding members of Proven Business Systems and is no rookie to the industry. Having graduated from Valparaiso University in 1973 with a Business Degree, John took his first job out of college with Xerox Corporation in 1974. While gaining tremendous industry experience and excelling as one of the top producers in the country.
After many years of toiling with the idea of starting his own company, he finally made the choice in 1982, opening Distinctive Business Products with 3 employees and operating out of a garage. With a strong focus on sales and customer service, the company grew to over 130 employees with 9 Chicagoland locations and topped the charts of Inc. 500 at #42 for America’s Fastest-Growing Private Companies within 10 short years.
In 1998, after 16 years, Distinctive was acquired by Global Imaging Systems, and John entered retirement. The retirement however was short-lived and having 2 sons already done with College, he thought it might be a perfect time start over again. In March of 2003, it was official, with 6 employees, and no customers, Proven Business Systems was born.
Vice President at Proven
Jeff Johnson is one of the founding forefathers of Proven Business Systems alongside business partner John Cosich, and has been in the industry for more than 24 years. Johnson was born and raised in Freeport, Ill. where he later enrolled at Southern Illinois University with a major in Justice Administration. His desired path was to go into Criminal Justice, but after meeting Cosich and starting as a salesman at his business solutions venture, Johnson broke the company sales record within one year. He continued for five years until he was promoted to management and in 2003 launched Proven with Cosich. He and Cosich grew the company to an over 30 million dollar endeavor and hopes to one day see Proven as the country’s largest technology company.
Jeff prides himself on providing the ultimate customer service experience and offers his personal cell phone number to customers so they can call him directly with any and all questions about their products and services.
Managing Director at Proven
Tory has contributed immensely to the overall company’s success as the Managing Director of Sales. Cosich graduated from DePaul University in 2003 with a Business Marketing degree and succeeded in sales and customer service relations at Proven right of out of school. In the summer of 2010, Cosich opened the company’s first office in the Loop, assisting his team in prospecting for new clients, contract negotiations and quarterbacking installations with project management teams. Shortly after in 2014, Proven was named Crain’s Chicago Business Fast Fifty for the 41st fastest growing company in Illinois, and made the Crain's list again in 2015 as the 32nd fastest growing.
Cosich currently sits on the Foundation Board for Sertoma Centre, Inc., an organization that provides services to more than 725 individuals with developmental, physical, emotional disabilities, and/or mental illness. Cosich is most proud that Proven helped raise over $50,000 for Sertoma’s Big Event fundraiser in 2014.
During his free time, Cosich enjoys outdoor activities and also participating in triathlon, playing golf, cooking and spending time with his wife.
Senior Account Manager at Proven
John Ross Cosich has been around the copier business since he was a little boy and knew it was his future career path at a young age. Cosich would beg his father, now CEO and Founder of Proven, to take him to work so he could play around in the warehouse and use the shredder. Throughout his childhood he would work in the warehouse and ride with the drivers delivering machines. In high school and summers in college, Cosich worked for the family business solutions company and learned the ropes from his father, which prepared him for when he entered the working world.
In 2004, Cosich graduated from DePaul University with a bachelor’s degree in Commerce. He then went on to work for his father and after 10 years, worked his way up to be a Senior Account Manager. Cosich currently manages the largest account Proven has and oversees clients throughout Illinois and Indiana.
Cosich’s wife, Allison, is part of the Proven team as well and the two have worked together for more than eight years. The couple just celebrated the birth of their baby boy. During John’s down time, he enjoys traveling, spending as much time with his family as possible, golfing, bowling and going to the movies.

In his role as COO, Cosich has developed a successful strategy that has allowed for accelerated growth exceeding 25% each year and has assembled a department now consisting of nearly 35 IT personnel. Cosich currently oversees all day to day Operations, as well as the Accounting, Solution Sales and IT departments.
