(IPDN) Exceeds 500,000 New Users Per Month

CHICAGO, July 7, 2015  — Professional Diversity Network, Inc. (“PDN”) (NASDAQ:IPDN), a developer and operator of online networks and technologies that provide access to employment opportunities for diverse professionals in the United States, announced today that it has sustained the rapid registered user growth it previously reported and surpassed 530,000 new registered users per month during June.

HIGHLIGHTS:

• 1,535,226 new registered users in the past 6 months
• 530,251 new registered users in June 2015 alone
• Nearly 2,000% new registered user growth on a month over month basis in June 2015 (over 530K) versus October 2014 (26.5K), last full month before Noble Voice acquisition
• Q2 bookings of $10.3 million, up nearly 800% compared to second quarter 2014

“In June we added over half a million new users, all of whom are job seekers who help us achieve our mission of matching diverse workers with the employers who need them,” said Jim Kirsch, CEO. Kirsch continued, “With the rollout of HireAdvantEDGE, our latest product, which helps employers improve candidate quality while reducing time to hire, it is critical to continue to bring new users into our system and feed our employer partners’ demand. The graph below proves the maxim that a picture is worth a thousand (or in this case over half a million) words, and tells us that we are succeeding.”

Sergio Zlobin, VP of Technology, added, “For a technology company to achieve success it must grow its user base in an efficient and sustainable way. At PDN our users are job seekers, and we have created a formula that allows us to add new users, at a declining marginal cost per user, while we are seeing similar growth in our employer partners. This means that we are growing supply (job seekers) while growing demand (employers), and matching the two in a manner we believe we can sustain and continue to grow. While our growth is always subject to market conditions and the like, we are absolutely prepared from a structural and technology perspective, and I am very confident that we can continue to refine and improve not only our formula for attracting new users but our technology for delivering them to employers.”

“It strikes me that when 2015 began we had enrolled just over 3 million users over the entire 12 year lifetime of our company,” said Mr. Kirsch. He continued, “So far in 2015 we have already registered over 1.5 million new users, with the rate growing every month. There is a very strong and fundamental relationship between registered users and our future potential. In recruitment, our greatest asset is the human capital inventory we can access and the efficiency in which we connect our diverse users and employers. That is why we are thrilled about the 497 employers utilizing our network to place our new registered users in careers across the nation. Our entire executive team believes that our prospects have never been better, and with $10.3 million in new bookings for the second quarter, the numbers we are reporting today back that up.”
