Andreas operated as Global Head of Information Security during one of Staffbase’s fastest growth phases, and he is exactly the kind of security leader a scaling SaaS business needs. He built our information security function from scratch and matured it in step with the company, pairing strategic vision with genuine hands-on expertise. Rather than a gatekeeper, he made security a business enabler: the certification portfolio he owned end-to-end directly accelerated enterprise sales cycles and unblocked major deals. He partnered closely with the C-level as a trusted advisor, translating security risk into clear business impact, and carried the executive presence to represent the company to auditors, enterprise customers, and regulators alike. A superb fit for any SaaS company seeking a business-minded CISO!
