Kazimi raises €2.2M pre-seed to tackle bot activity in mobile marketing

Berlin-based mobile cybersecurity startup
Kazimi has raised €2.2 million in an oversubscribed pre-seed round to scale its
technology for securing and verifying first-party data used by app developers
for marketing analytics and AI. The round was led by Market One Capital, with
participation from IBB Ventures and several mobile and technology industry
executives, including Petri Hyökyranta (former Rovio CTO), Janne Peltola
(former Supercell data scientist), and Erik Massmann (former CFO of Birkenstock
Group and Sportradar).

Kazimi is developing security technology that
helps mobile app developers determine whether activity within their apps comes
from genuine users or automated bots. Its solution secures communication
signals generated by an app, enabling developers to collect and verify
first-party data, identify non-human activity and maintain user privacy.

The company is addressing a growing challenge
for mobile businesses as automated internet traffic increases. Data from
Cloudflare indicates that bot activity exceeded human activity on the internet
in 2026, while AppsFlyer reports that bots remain a major source of fraudulent
activity across mobile channels.

Kazimi uses privacy-preserving cryptographic
proofs to verify interactions without compromising users’ personal data. The
company says the technology is designed to improve the accuracy of data used
for analytics, marketing and AI applications while supporting compliance with
data protection requirements.

Until now it has been technically impossible
for app developers to have true visibility on which signals originate from real
users and which signals come from bots. With our advanced security solution, we
are closing the loop and enabling app developers to protect their most
important resource – their first party data,

said Andreas Naumann, co-founder
and Chief Product Officer of Kazimi.

Kazimi’s founders previously worked on
security and fraud-detection systems at mobile measurement company Adjust
before its acquisition by AppLovin in 2021. The team has also developed
security systems for other mobile analytics companies and networks.

Kazimi’s technology is aimed at apps that rely
on marketing spending to acquire and retain customers. Its current clients
include mobile gaming studios, rewards platforms and fintech apps.

The company plans to use the funding to scale
its technology and expand its presence in the global mobile advertising market.
