InMobi announced its acquisition of MobileAction on May 7, bringing one of the largest app intelligence datasets in the market under its roof. The numbers are substantial: 90 million ad creatives tracked, 6 million keywords monitored, and data spanning 5 million apps across both iOS and Android.
MobileAction's client list includes Google, Meta and DoorDash. Its platform provides competitive intelligence on app store optimisation, paid user acquisition and creative performance across mobile advertising networks. InMobi, which already operates one of the largest independent mobile ad platforms globally, now adds a data layer that strengthens its position in iOS specifically.
The timing is deliberate. Since Apple introduced App Tracking Transparency in 2021, the mobile advertising ecosystem has been progressively losing visibility into iOS user behaviour. Attribution has become harder. Creative testing cycles have lengthened. Competitive intelligence on what ads are running and where has become a genuine strategic advantage rather than a nice-to-have.
Ad creatives tracked across mobile networks, now consolidated under InMobi's platform
MobileAction's dataset addresses this directly. By tracking creative deployment across networks at scale, it provides advertisers with visibility into competitor strategies, creative trends and keyword opportunities that are otherwise invisible in a post-ATT world.
InMobi has indicated the acquisition will be integrated into its existing Appsumer platform (acquired in 2022), creating an end-to-end mobile marketing intelligence stack covering media buying, measurement and competitive analysis.
Why it matters
For Australian app marketers and mobile-first businesses, this consolidation signals where the market is heading. The companies with the best proprietary data on mobile advertising performance will have a structural advantage in campaign optimisation.
Australia's iOS market share sits above 55%, making the iOS intelligence gap particularly acute for local advertisers. Any tool that restores visibility into iOS creative performance and competitor activity has direct value.
The broader trend is clear: adtech is consolidating around data moats. Companies that own unique datasets (creative libraries, keyword indices, app performance benchmarks) are being acquired precisely because that data cannot be replicated through standard API access.
What to do about it
Mobile advertising intelligence is consolidating fast. The businesses that invest in visibility now will outperform those relying on increasingly blind optimisation.
