We’re excited to join Buzzvil and leverage their significant experience with dozens of publishers who have already implemented their lockscreen SDK, BuzzScreen.”

John Lee, CEO of Buzzvil, stated, “The acquisition of Slidejoy is Buzzvil’s emergence as a truly global company with operations in Asia and now, the Americas. Slidejoy is the perfect opportunity for Buzzvil to diversify its geographic footprint while bringing on a world-class team.” He added, “With our combined scale and geographic reach, we are now positioned to propel lockscreen advertising forward and shape the mobile advertising landscape worldwide.”

Slidejoy will retain its distinct brand and its CEO, Robert Seo, will become CEO of Buzzvil, Inc., the US subsidiary of Buzzvil Co., Ltd. The combined company will continue to focus on its respective mobile apps, Slidejoy and HoneyScreen, as well as expand its publisher base for the B2B offering, BuzzScreen.

As part of today’s announcement, the company announced that its first BuzzScreen publisher in the US, an MVNO, will launch within this month and expects to complete an additional twelve BuzzScreen partnerships by the first half of 2017.
