€2.2m · Pre-Seed · Software · Berlin, Germany
Berlin-based mobile-security startup Kazimi has raised €2.2m in an oversubscribed pre-seed round led by Market One Capital, with participation from IBB Ventures and mobile-industry executives Petri Hyökyranta, Janne Peltola and Erik Massmann, according to Tech.eu and EU-Startups. The company says the capital will help scale its security technology and address the global mobile-advertising market.
Kazimi is building a verification layer for signals generated inside mobile apps. The company says it secures those communications so developers can distinguish genuine users from bots, protect first-party data and keep personal information private. Its current customers include mobile-gaming studios, rewards platforms and fintech apps, where automated activity can distort acquisition, retention and monetisation data.
Signal integrity moves upstream
Most fraud tools analyse activity after data has entered a marketing or analytics system. Kazimi instead aims to verify the origin of an event before downstream teams use it. The company's product material describes checks for device emulation, app cloning, tampering, code injection and other manipulation. It says privacy-preserving cryptographic proofs let customers identify non-human activity without relying on personally identifiable information.
That changes the commercial proposition from another reporting dashboard into infrastructure for data quality. A publisher that can exclude bot-generated installs or purchases earlier can make cleaner user-acquisition decisions and avoid training optimisation systems on corrupted signals. The value therefore depends less on producing another fraud score and more on whether Kazimi can make its verification dependable across the mobile environments and business-intelligence systems customers already use.
Distribution depends on the mobile stack
The founding team brings direct experience from mobile measurement. EU-Startups reports that Chase Gummer, August Joseph, Ville Mikkola and Andreas Naumann previously worked on security and fraud-detection systems at Adjust and other mobile-analytics businesses. Kazimi also announced an integration partnership with server-side measurement platform Hardal before the financing, pointing to a distribution route through tools developers already use.
Those integrations are also the execution test behind the round. Fraud detection becomes more useful when it sits close to the app signal, but each framework, analytics pipeline and customer workflow adds implementation work. The financing gives Kazimi room to broaden that coverage; commercial progress will depend on making the security layer easy to deploy while preserving the privacy and deterministic-verification claims that distinguish it from probabilistic, after-the-fact detection.
