Others

• AppsFlyer: AppsFlyer is a leading mobile attribution and marketing analytics platform. Like Adjust, it is embedded as a standard ModuleApps Plug-in and serves many of the same Japanese enterprise customers, positioning it as a partner-competitor in the attribution stack.
• Adjust: Adjust is a global mobile attribution and analytics platform. It is standard-integrated as a ModuleApps Plug-in in ModuleApps2.0, making it both a partner and an adjacent competitor in the attribution layer DearOne's customers rely on.
• Amplitude: Amplitude is a leading product analytics platform and DearOne's primary analytics partner (DearOne is Amplitude's Japan general distributor). While complementary, Amplitude's standalone product competes with the analytics and ModuleApps Roid visualization features within ModuleApps2.0.

Broad incumbents

While broader than ModuleApps2.0, it competes for the same enterprise mobile-app-and-marketing budget with bundled CRM, personalization, and analytics capabilities.

• MoEngage: MoEngage is a cross-channel customer engagement platform integrated with ModuleApps2.0 (used in the ASBee case). It targets the same Japanese and APAC enterprise customers with comparable push, journey, and personalization features, making it a partial competitor.

Regional players

• Kaizen Platform: Kaizen Platform is a Japan-based digital experience and CRO platform serving Japanese enterprise clients with website and mobile optimization, A/B testing, and analytics—adjacent to but broader than DearOne's in-app engagement focus.

Direct peers

• KARTE (Plaid): KARTE is a real-time customer data platform focused on the Japanese market, used by major retailers and brands for personalization and CX analytics. It overlaps with DearOne's customer data, personalization, and analytics modules within ModuleApps2.0.
• Repro: Repro provides a mobile customer engagement and analytics platform widely used by Japanese enterprises for in-app messaging, push notifications, and user behavior analysis. It competes directly with DearOne's scenario engine, push, and analytics capabilities.
