John Barr Will Oversee Operations for Global E-Discovery Company

Denver, CO—July 27, 2016—John R. Barr, a veteran technology and operations executive, has been named president of Catalyst, the award-winning e-discovery company. He will report to Catalyst’s founder and CEO John Tredennick and oversee the company’s operations, development and internal management.

"John is an accomplished leader in technology and operations who brings a winning combination of leadership skills, technical expertise and business savvy,” said Catalyst founder and CEO John Tredennick. "We are thrilled that he will help lead us into our next phase of growth.”

“I am very excited to join Catalyst and very grateful for the opportunity to work with its exceptional staff,” said Barr. “Having helped launch three start-ups and helped drive the growth of several technology companies, I look forward to helping to build Catalyst’s global footprint.”

In 2007, Barr joined Yieldex, the award-winning big data analytics company that helped publishers maximize digital advertising revenue, as its chief operating officer until its acquisition in 2015 by the internet advertising company AppNexus. He remained with AppNexus into 2016 to oversee the Yieldex integration.

As Yieldex COO, Barr helped grow the company from four to 75 employees and from having no product or revenue to becoming the recognized leader in the field with nearly $20 million in revenue. He was responsible for driving the company’s profitability by increasing efficiencies, reducing costs, forming strategic partnerships and managing vendor relationships.

Before Yieldex, Barr was chief technology officer for two technology start-ups and was vice president of engineering at Streampoint Financial, where he helped develop an internet-based workflow system for retail broker-dealers. Earlier, Barr was senior vice president for technology and operations at iMcKesson, the healthcare services and information technology company, and senior vice president, product development and technology, at Access Health before its acquisition by iMcKesson.

A resident of Colorado, Barr has a bachelor’s degree in engineering from McMaster University in Ontario. He is an avid cyclist, runner and kite boarder.
