App User Acquisition

Remerge

Paid

Remerge is a mobile-first demand-side platform specialized in app retargeting and re-engagement rather than broad acquisition. It buys programmatic in-app inventory to win back lapsed users, drive repeat purchases, and lift lifetime value for gaming, e-commerce, and on-demand apps. Working alongside mobile measurement partners, it runs deterministic and contextual campaigns that respect SKAdNetwork and App Tracking Transparency constraints on iOS, and it reports incremental impact through holdout-based measurement rather than relying on last-touch attribution alone.

What it does

Remerge is a demand-side platform built specifically for mobile app retargeting and re-engagement rather than broad user acquisition. It buys programmatic in-app advertising across exchanges to reach existing users who installed but went quiet, encouraging them to return, complete purchases, or resubscribe. Campaigns plug into mobile measurement partners such as AppsFlyer and Adjust, and Remerge leans on incrementality testing with holdout groups to prove it is driving additional revenue rather than taking credit for organic returns. On iOS it operates within SKAdNetwork and the contextual constraints introduced by App Tracking Transparency. Gaming, e-commerce, and on-demand apps with large dormant audiences are its core users.

Where it fits

Remerge sits downstream of user acquisition in the app-growth funnel, buying programmatic in-app media to re-engage users your MMP already knows.

Core features

  • Programmatic app retargeting across in-app exchange inventory
  • Re-engagement campaigns to win back lapsed and dormant users
  • Incrementality measurement with holdout groups, not last-touch only
  • Integrations with AppsFlyer, Adjust, and other MMPs
  • SKAdNetwork and ATT-compliant targeting on iOS

Best for

  • Gaming and e-commerce apps with large dormant user bases
  • UA teams that have exhausted easy acquisition and need retention lift
  • Marketers who want incremental, not last-touch, retargeting

Beginner notes

  1. Run a clean holdout from day one — retargeting numbers look great on last-touch, so incrementality testing is the only honest read on value.
  2. It needs scale to work; very small or brand-new apps usually lack the dormant-user volume that makes re-engagement economical.
  3. Coordinate suppression lists with your UA campaigns so you are not paying to retarget users another channel is already converting.
