Berlin startup Kazimi has pulled in €2.2 million in an oversubscribed pre-seed round to push its mobile cybersecurity tech further. The money is meant to help app developers tell whether the activity inside their apps is coming from real people or automated bots.
Market One Capital led the round, with IBB Ventures joining in. So did a handful of people with long mobile and tech résumés, including Petri Hyökyranta, Janne Peltola and Erik Massmann.
Kazimi’s pitch is aimed at a familiar headache in mobile marketing: developers need first-party data for analytics, AI and ad spend decisions, but they also need to know that the signals they’re collecting are clean. The company says its system secures the communication signals generated by an app, then uses privacy-preserving cryptographic proofs to verify interactions without exposing personal data.
That matters because bot traffic keeps creeping up. Cloudflare says bot activity passed human activity on the internet in 2026, and AppsFlyer says bots are still a major source of fraud across mobile channels. Kazimi says its approach makes it possible to improve the accuracy of data used for analytics, marketing and AI while still fitting data-protection requirements.
The founders are not new to this corner of the industry. They previously worked on security and fraud-detection systems at Adjust before AppLovin bought the company in 2021, and they have also built security systems for other mobile analytics businesses and networks. Kazimi’s current customers include mobile gaming studios, rewards platforms and fintech apps, and the company plans to use the new funding to scale and expand globally in mobile advertising.
My take — AI-written commentary, not fact-checked reporting
This is the sort of startup that exists because the rest of the industry made a mess and then decided to buy a mop. If mobile marketers want first-party data so badly, they should probably stop treating bot checks like a side quest. Fraud has a habit of finding the cracks people leave for growth.
