What ContextSDK does
ContextSDK is a Vienna-based mobile software development kit (SDK) provider that helps application developers optimize in-app monetization by determining the optimal moment to engage users. Founded in 2022 and operating with 1-10 employees, the company targets iOS and Android developers across gaming, subscription, and content app categories, offering two core products: ContextDecision, which uses machine learning to score the appropriateness of showing upsells, paywalls, ads, or rating prompts based on over 300 built-in device and behavioral signals; and ContextPush, which delivers non-time-sensitive push notifications at contextually optimal moments by classifying device eligibility via Background Operation Time. The platform processes structured device signal data (motion, battery, screen state, time patterns) plus optional custom developer-supplied signals, with on-device inference using lightweight (~500KB) models that are trained server-side and deployed over-the-air.

ContextSDK product offering
Product offeringCore offering
ContextSDK provides a mobile software development kit (SDK) that uses on-device machine learning models to analyze over 300 real-world user context signals (motion, time, location patterns, device state) and determine the optimal moments for in-app monetization prompts and push notifications. The platform consists of two core modules—ContextDecision for in-app offer/paywall/ad timing and ContextPush for context-aware push notification delivery—distributed as a unified SDK across iOS, Android, Flutter, Unity, and React Native.
Product overview
ContextSDK is a mobile SDK platform providing two core modules: ContextDecision for optimizing in-app monetization timing (upsells, paywalls, ads) using ML predictions, and ContextPush for context-aware push notification delivery. The unified SDK supports iOS, Android, Flutter, Unity, and React Native, processes over 300 built-in device signals, operates without PII or app permissions, and deploys custom ML models over-the-air. Integration guides exist for RevenueCat, Superwall, Purchasely, and StoreKit for revenue tracking, and ContextPush connects with OneSignal, Customer.io, and custom backends for notification delivery.

ContextSDK competitors and assessment
Company assessmentDirect peers
- CleverTap: Mobile customer engagement and retention platform offering AI-powered timing of push notifications, in-app messages, and onboarding flows. Direct competitor to ContextSDK's core offering for mobile app developer mindshare.
- Airship: Mobile engagement platform specializing in push notifications, in-app messaging, and journey orchestration with ML-driven timing. Overlaps directly with ContextDecision and ContextPush use cases for app developers.
- MoEngage: Mobile-first marketing automation platform with AI-driven send-time optimization and in-app engagement orchestration. Comparable developer-customer base and similar focus on app-lifecycle monetization moments.
- Swrve: Mobile engagement platform with in-app messaging, push orchestration, and A/B testing for enterprise apps. Directly comparable in customer segment (mobile app developers) and timing-driven engagement focus.
- Kumulos: Mobile app engagement and push notification platform targeting app development agencies and SMB mobile developers. Closely comparable in horizontal mobile developer focus and timing-driven notification features.
- Pushwoosh: Omnichannel customer engagement platform with push notifications and in-app messaging powered by ML-driven segmentation. Direct overlap with ContextPush's notification timing use case for app developers.
Broad incumbents
- Iterable: Cross-channel customer engagement platform with send-time optimization across email, push, and in-app. A larger incumbent serving similar developer and product teams, though with a broader channel portfolio.
- Braze: Enterprise customer engagement platform with AI-powered send-time and channel optimization across mobile push, in-app, and email. Significantly larger scale incumbent serving the same enterprise mobile developer customers.
- OneSignal: Push notification infrastructure platform that ContextSDK integrates with via webhooks. OneSignal is both a distribution partner and a potential competitor as it expands its own timing and engagement features.
- Customer.io: Customer data platform and messaging orchestration tool with webhook-based integrations. ContextSDK integrates with Customer.io today, but Customer.io could ship native context-aware timing as a competing feature.
