RedMimicry secures million-dollar seed funding to advance realistic cyberattack testing

• RedMimicry secures seven-figure seed funding from High-Tech Gründerfonds (HTGF), Capital Square (Hamburg), and superangels (Munich). 
• First platform to realistically and automatically simulate complex, multi-stage cyberattacks. 
• Organizations use RedMimicry to emulate threat actors like LockBit and Black Basta, validate their defenses, and boost cyber resilience. 

RedMimicry, a provider of a platform for the realistic emulation of complex cyber-attacks, has announced the successful completion of a seed financing round. The round was led by High-Tech Gründerfonds (HTGF) with participation from Capital Square from Hamburg, superangels from Munich, and several well-known business angels. This investment will allow RedMimicry to develop its technology further and increase its sales activities. 

Preparing for real attacks 

Many companies only test their defences selectively and under unrealistic conditions. This means that vulnerabilities in processes, technology, and collaboration can remain undetected. However, regulatory requirements such as DORA and NIS-2 stipulate that companies must comprehensively and regularly test their security measures against current attack chains. RedMimicry provides repeatable emulations that enable companies to thoroughly validate their cyber defences against threat scenarios, such as malware or targeted attacks. This enables customers to increase their security sustainably while reducing costs and effort. 

As well as working directly with customers, RedMimicry collaborates with a growing network of partners to help companies of all sizes enhance their security processes. 

Focusing on specific attack targets 

The fresh financing will enable RedMimicry to further develop its product platform, paying particular attention to specific threat scenarios, such as attacks on critical infrastructure (operational technology, OT) or financial service providers. RedMimicry is also investing in its sales team and expanding its partner network. 

Alexander Rausch, founder and CEO of RedMimicry, said: “Our vision is to enable companies to protect themselves independently and effectively against increasingly complex cyber-attacks. With the support of experienced investors, we can advance our technology significantly and expand our market position.” 

Constantin Schlachetzki, Director of Cyber Defence at the German Cyber Security Organisation (DCSO), said: “DCSO’s customers rely on first-class security services. RedMimicry supports our assessments with advanced attack simulations, helping us to deliver accurate and effective evaluations.” 

Björn Sykora, Principal at HTGF, said: “Alex and Stefan combine technical excellence with entrepreneurial vision. With RedMimicry, they are addressing one of the greatest risks companies are currently facing: protection against cyber-attacks. They provide a European security solution that benefits both medium-sized and large companies.” 

Martin Ostermayer, Co-Founder Capital Square: “We’re excited to back RedMimicry as they revolutionize how companies prepare for and defend against sophisticated cyberattacks. Their bold vision and outstanding team embody exactly the kind of ambition and expertise we look for in founders – and we’re confident they’ll set new standards in cybersecurity.”  

Franzi Majer, Founding Partner at superangels, said: “We’re excited to back RedMimicry, whose realistic cyberattack simulations help companies uncover vulnerabilities before attackers do. Their technical excellence, market relevance, and visionary team make them exactly the kind of startup we love to support.”
