InMobi is a mobile-first advertising platform with a DSP powered by Helix AI, a proprietary intelligence engine that processes more than 4 million bid requests per second. The platform covers user acquisition, re-engagement, and publisher monetization within a single mobile-focused ecosystem.
InMobi also operates its own consumer platforms – including Glance AI, 1Weather, and Roposo – which generate first-party behavioral data that feeds directly into Helix.
Helix AI
Helix serves as the central intelligence layer across InMobi DSP. It unifies user acquisition and re-engagement into one decision-making framework, using real-time behavioral and contextual signals to optimize delivery.
Supply Path Optimization uses recurrent neural networks to select the most effective paths to high-value users while eliminating fraudulent traffic at the source. Campaign optimization runs on cleaner data than most open-exchange approaches because fraud is removed before it reaches downstream algorithms.
Publisher and SDK reach
InMobi’s SDK-based supply gives advertisers access to in-app inventory from direct publisher integrations. In 2025, InMobi achieved 80% penetration among China’s top 100 gaming publishers, with partner revenue doubling between H1 2024 and H1 2025. The platform’s SDK inventory is unique: it’s not easily accessible through third-party exchanges, giving advertisers differentiated supply.
iOS expansion
InMobi acquired MobileAction, an AI-powered app growth and App Store Optimization platform, extending its capabilities across Apple’s ecosystem. The acquisition connects ASO performance data with in-app advertising signals, strengthening the iOS user acquisition offering end to end.
Privacy-first approach
Helix AI is built with privacy compliance as a core principle. Advanced contextual targeting reduces reliance on individual user identifiers, keeping performance stable as identifier availability declines across mobile environments.
Who it’s for
InMobi suits mobile app marketers in gaming, fintech, e-commerce, and entertainment who need SDK-level inventory access combined with AI-driven campaign optimization. Its mobile-first focus and owned first-party data give it depth that general-purpose programmatic DSPs don’t match for in-app advertising.
