Edinburgh-based Approov Limited, an innovator in mobile app and application programming interface (API) security, said on Monday it has successfully closed a £5 million Series A funding round.

The investment, spearheaded by the British Business Bank’s Investment Fund for Scotland, managed by Maven Capital Partners, also saw participation from Souter Investments and existing investors Lanza techVentures and Scottish Enterprise.

“This funding milestone enables Approov to bolster its Research & Development team in Edinburgh, driving the creation of advanced technologies to secure mobile applications and APIs against evolving threats in real time, including those powered by AI,” said Approov, which also has a base in Palo Alto.

“The company’s patented app attestation solutions protect apps from tampering and fraudulent API access, offering a critical defense in today’s rapidly shifting cyber threat landscape​​.”

Approov CEO Ted Miracco said: “As the threat landscape continues to evolve, developers and enterprises alike are recognizing that mobile app security cannot be an afterthought.

“This funding marks a pivotal moment in our mission to ensure that every mobile app instance is authenticated and that backend APIs are protected from fraud, abuse, and unauthorized access.”
