NEW YORK, NY–(Marketwired – Dec 12, 2013) –  MediaMath, the creator of the Terminal One Marketing Operating System™ for digital marketers, has been honored as one of the "Best Medium-Sized Companies to Work For in 2014," a Glassdoor Employees' Choice Award. The Employees' Choice Awards rely solely on the input of employees, who elect to provide feedback on their jobs, work environments and companies via Glassdoor's anonymous online company review survey.

MediaMath, a digital media technology company headquartered in New York City, was ranked number 6 on Glassdoor's list. The company's CEO, Joe Zawadzki, commented, "Over the past six years, MediaMath has cultivated an incredible team of talented, smart and driven people and they are undeniably our greatest asset. Every day, we strive to provide our employees with the opportunity to contribute to the company's growth and innovation, and it's an honor to be recognized for that effort."

MediaMath has grown its number of employees by 100% over the past year and, as it continues its rapid growth, is actively recruiting globally, across all roles — from Engineering to Sales to Human Resources and beyond. "At its inception, Joe and the early executive team has laid the foundation for a positive corporate culture," said Peter Phelan, MediaMath's Chief People Officer. "Not only do we do our best to ensure a collaborative working environment, but also one that is energetic and fun and makes it exciting to work hard every day."

"Glassdoor is working to create greater workplace transparency and is committed to helping people find jobs they love," said Glassdoor CEO & Co-founder Robert Hohman. "Through the Employees' Choice Awards, we aim to highlight those employers that excel in keeping employees satisfied and engaged."

The Glassdoor company review survey includes both quantitative and qualitative questions designed to capture a genuine and authentic inside look at what it's like to work at particular jobs and companies. The survey asks employees to rate their satisfaction with the company overall, and key workplace factors like career opportunities, compensation and benefits, work/life balance, senior management, as well as culture and values. In addition, employees are asked to describe the best reasons to work at their company as well as any downsides.

The Best Medium-Sized Companies to Work for List is determined using company reviews shared by U.S. based employees who elected to participate in the survey between November 14, 2012 and November 12, 2013. To be considered for the list, a company must have between 250-999 employees and have received at least 20 approved company reviews during the window of eligibility. The final list is compiled based on Glassdoor's proprietary algorithm, and takes into account quantity, quality and consistency of reviews. To request complete methodology, email
