One of Israel’s largest mobile software companies, IronSource, announced on Thursday that it will merge with a San Francisco peer, Supersonic. The companies did not disclose details of the transaction.
IronSource, a five-year-old company that you may have spotted on Fortune’s Unicorn List, calls itself a “platform for software discovery, distribution, and delivery across platforms and devices.” What that means is that it makes software development kits, or SDKs, for mobile operating systems such as Google Android to improve how app-installation promotions target users.
Six-year-old Supersonic, meanwhile, focuses primarily on mobile monetization. It also supports its own SDK, aimed at video applications, such as “interstitial” (which interrupt a user’s flow to display an ad) and “offerwall” (monetary, credit, or point-based incentives in exchange for action) promotions. Both companies offer related data analytics services.
The deal brings together largely complementary product portfolios in a bid for scale and a fuller services “stack,” to use industry jargon. The combined company will reach more than 1 billion users and are expected to generate $450 million in revenue this year.
“There are many inconsistencies in the mobile industry that we are poised to solve with this merger—issues such as cross screen tracking, mobile targeting and reporting,” IronSource CEO Tomer Bar Zeev said in a statement. “We believe that combining Supersonic’s strengths with ironSource’s data, scale, and technology will position us to be the market leader.”
