Stoïk secures €20M Series C to accelerate AI cyber insurance in Europe
French insurtech startup Stoïk has raised a €20 million Series C funding round to scale its AI-powered cyber insurance and protection platform across Europe, as small and medium-sized enterprises (SMEs) face a sharp rise in ransomware, phishing, and data breach incidents. The company already protects more than 10,000 SMEs and plans to deepen its presence in key markets including France and Germany.
A data-driven response to escalating cyber threats
Across Europe, cybercrime has become one of the most pressing operational risks for smaller businesses. While large enterprises typically have dedicated security teams and significant budgets, SMEs often lack both the tools and expertise to defend themselves against increasingly sophisticated attacks. This widening vulnerability gap has created a fast-growing market for specialised cyber insurance combined with proactive protection.
Stoïk positions itself at the intersection of insurtech, cybersecurity, and artificial intelligence. Instead of offering traditional policies based solely on questionnaires and historical loss data, the company uses AI algorithms and continuous threat intelligence to assess risk in real time and help clients prevent incidents before they occur.
How Stoïk’s AI-powered model works
The core of Stoïk‘s proposition is a combined package of cyber risk assessment, continuous monitoring, and insurance coverage, designed specifically for SMEs that often rely on outsourced IT and cloud-based tools.
Automated cyber risk scoring
Using external scanning and internal questionnaires, Stoïk builds a detailed risk profile for each client. Its AI models analyse exposed services, software versions, misconfigurations, and known vulnerabilities. This generates a dynamic cyber risk score that informs underwriting decisions and pricing, enabling more precise and transparent risk-based premiums.
Continuous monitoring and alerts
Beyond the initial assessment, Stoïk offers ongoing cybersecurity monitoring. The platform tracks changes in the client’s external attack surface and correlates them with emerging threats. When a critical vulnerability or suspicious exposure is detected, the system triggers alerts and offers practical remediation guidance, helping SMEs reduce their likelihood of a successful attack.
Integrated incident response and coverage
In the event of an attack, Stoïk provides access to specialised incident response teams, legal support, and communications experts, alongside financial coverage for costs such as data recovery, business interruption, and potential liability. This integrated model aims to shorten recovery times and limit the operational and reputational damage that can cripple smaller firms.
Strategic focus on European SMEs
With more than 10,000 SMEs already covered, Stoïk is emerging as a key player in Europe’s rapidly evolving cyber insurance market. The company targets sectors such as professional services, manufacturing, retail, and healthcare—industries that are increasingly digital but often under-protected.
The new €20 million Series C round will be used to expand the company’s presence in major European markets. Germany, where Stoïk is building a dedicated local team, is a particular focus due to its dense SME base and tightening regulatory expectations around data protection and IT security.
Rising regulation and board-level awareness
European regulatory frameworks, including the NIS2 Directive and stricter enforcement of GDPR, are pushing organisations of all sizes to strengthen their cyber resilience. For SMEs, this often means seeking partners that can combine technical support with financial protection.
As boards and owners become more aware of the financial impact of cyber incidents—from downtime and ransom payments to regulatory fines—demand is rising for solutions that can quantify risk and demonstrate continuous improvement. Stoïk’s data-driven approach and regular reporting are designed to help SMEs communicate cyber posture not only to regulators, but also to banks, insurers, and customers.
Competitive landscape in European insurtech
The funding round underscores investor confidence in the broader insurtech segment, where startups are leveraging machine learning, automation, and cloud-native architectures to modernise underwriting and claims. Within cyber insurance specifically, competition is intensifying as both incumbents and new entrants seek to capture a share of the SME market.
What differentiates Stoïk is its emphasis on prevention and real-time visibility, rather than treating cyber insurance as a purely reactive financial product. By embedding security tooling directly into the insurance relationship, the company aims to reduce loss ratios while delivering tangible value to clients on a daily basis.
Plans for product and partner expansion
The fresh capital will support further investment in AI research, threat detection, and automation capabilities, as well as the development of new modules tailored to specific industries and regulatory regimes. Stoïk also plans to deepen its network of broker and channel partners across Europe, making it easier for SMEs to access cyber coverage through existing insurance relationships.
As cyberattacks continue to rise in frequency and sophistication, the combination of advanced analytics, proactive defence, and tailored insurance is set to become a standard expectation rather than a niche offering. With its €20 million Series C, Stoïk is positioning itself to be one of the defining European players in this new era of AI-enabled cyber risk management for SMEs.
