App User Acquisition
InMobi
InMobi is a global mobile advertising platform offering a demand-side buying solution, an exchange, and rich-media creative formats for app marketers running user-acquisition and re-engagement campaigns. Advertisers reach in-app audiences across a large publisher supply base with targeting, programmatic buying, and interactive ad units such as interstitials and video. It pairs with InMobi's broader ecosystem of monetization and audience products, making it relevant for performance marketers and brands seeking scaled mobile inventory outside the largest self-serve networks.
What it does
InMobi is a mobile advertising platform that lets app marketers buy in-app inventory at scale for user acquisition and re-engagement. Through its demand-side solution and exchange, advertisers reach audiences across a large base of mobile publishers, using targeting, programmatic bidding, and interactive creative formats like interstitials, native units, and video. Because InMobi also operates monetization and audience products, buyers can tap supply that does not always flow through the largest self-serve networks, which is useful when teams want incremental reach or different inventory mixes. Campaigns are typically optimized toward installs and post-install events, with measurement handled through mobile measurement partners. It suits performance marketers and brands that need scaled, programmatically accessible mobile inventory beyond the dominant ad networks.
Where it fits
InMobi sits at the launch stage of mobile UA as a demand and supply source for buying in-app inventory programmatically.

Beginner notes
- Connect a mobile measurement partner first so installs and post-install events attribute correctly before scaling spend.
- Test creative formats separately, since interstitial, native, and video units perform very differently by app category.
- Watch for invalid or low-quality traffic and validate results against your MMP rather than dashboard numbers alone.
