Global adtech firm InMobi has acquired MobileAction, an AI-powered platform focused on iOS app growth and analytics, as it looks to strengthen its presence in the iOS advertising ecosystem. The financial terms of the deal were not disclosed.
Founded in 2013 and headquartered in San Francisco, MobileAction provides tools for Apple Ads and App Store Optimization (ASO), enabling developers and marketers to improve app visibility and user acquisition. Its platform is used by major global brands including Google, Meta, DoorDash, Square, Zalando, Playtika, and Priceline.
The acquisition is expected to enhance InMobi Advertising’s capabilities by combining MobileAction’s expertise in app discovery, analytics, and performance marketing with InMobi’s global ad infrastructure and consumer commerce platform, Glance.
MobileAction brings significant data scale to the combined entity, with access to insights across 90 million creatives, 6 million keywords, 5 million apps, 100,000 publishers, and 500,000 advertisers. InMobi said this will enable brands to improve targeting, campaign optimisation, and return on ad spend through AI-driven tools.
Following the acquisition, MobileAction will continue to operate as an independent platform, while its teams across the United States, Europe, and Turkey will integrate with the InMobi Group. The company plans to expand MobileAction’s footprint across the US, APAC, and MENA regions.
The deal comes amid growing competition in mobile advertising, particularly within the iOS ecosystem, where privacy changes have increased the importance of data driven optimisation tools.
In December 2025, InMobi raised $350 million in funding from Varde Partners, Elham Credit Partners, and SeaTown Holdings, while also reportedly buying back a 25–30% stake from SoftBank, signalling a broader strategic realignment.
