ContextSDK is an on-device context intelligence layer for mobile apps, founded by Felix Krause and Dieter Rappold and backed by Speedinvest. Its SDK processes 300+ real-world device signals (accelerometer, gyroscope, motion, screen state, ambient signals) through on-device machine learning to determine what a user is doing in the moment — commuting, relaxing, working, or being active — within seconds of app launch, with no PII collected and a ~0.6 MB footprint. Two products build on this: ContextDecision for intelligent timing of in-app actions and messages, and ContextPush for context-aware push notification delivery. ContextSDK ships native clients for iOS (Swift), Flutter, React Native, and Unity, with Android in beta, and is SOC 2 Type 2 certified and GDPR compliant.
