IronSource

ironsrc.com is the former primary domain of IronSource, an Israeli software company specializing in mobile advertising, game development tools, and app monetization platforms. Founded in 2010 by Tomer Bar Zeev and Tamir Ben-Shalom, IronSource grew rapidly to become a leading provider of in-app advertising solutions, powering thousands of mobile applications worldwide. Its platform included services like ironSource SDK, a mediation and monetization toolkit; Supersonic, a game development studio; and Tapjoy, a rewarded advertising network acquired in 2021. In 2022, Unity Technologies, a major cross-platform game engine developer, acquired IronSource in a $4.4 billion all-stock deal, completing the acquisition in November 2022. Following the acquisition, IronSource's brand and technology were integrated into Unity's ecosystem, and its primary domain, ironsrc.com, was set to redirect to unity.com. The domain no longer hosts independent content; instead, visitors are redirected to Unity's corporate website. The DNS configuration shows A records pointing to IP 62.0.96.176 in Israel, with mail exchange records through Google Workspace. The domain was registered in 2012 via Amazon Registrar, Inc. and is set to expire in 2027. IronSource went public via a SPAC merger in June 2021, valued at $11 billion, and reported revenue of $550 million in 2021. The company employed over 1,500 people globally, with key products including the ironSource API, Tapjoy's offerwall, and the Supersonic publishing platform. Despite its redirect status, ironsrc.com retains historical significance in the mobile advertising industry, representing a company that played a key role in shaping the modern app monetization landscape. Its traffic rank of approximately 135,000 globally indicates residual traffic from former users and ongoing references. The acquisition by Unity has effectively subsumed the IronSource brand, but the domain remains as a redirect, preserving link equity and brand recognition. This analysis is based on WHOIS and DNS data, along with publicly available information about the company's history and acquisition.
