Equixly raises €10M to tackle the API security crisis with agentic AI hackers

Italy-based Equixly has raised €10 million in Series A funding to scale its proprietary agentic AI hacking platform. The round was led by 33N Ventures and joined by Alpha Intelligence Capital, with additional participation from existing investors JME Ventures, 360 Capital and Fondazione Cassa di Risparmio di Firenze.

Founded in 2022 by brothers and serial entrepreneurs Mattia and Alessio Dalla Piazza, alumni of IBM, UniCredit and Accenture, Equixly is a penetration testing platform built for the scale and complexity of today’s API-driven web.

As organisations rely more on APIs, existing security methods are struggling to keep up with fast-evolving, complex threats. Manual penetration testing is thorough but costly and hard to scale, while automated scanners are easier to run but often miss business-logic flaws, where attackers exploit normal workflows to steal data, hijack accounts or move funds. This forces organisations to choose between scalability and depth of security.

Equixly identifies up to 80 per cent more vulnerabilities than standard Dynamic Application Security Testing (DAST) tools at the development stage and, by mapping a company’s entire API landscape, can reveal the 10–20 per cent of “shadow” endpoints that enterprises are often unaware of, while keeping false positives below 1 per cent. This enables teams to focus on resolving real issues rather than investigating false alarms.

The platform uses proprietary AI agents to continuously detect vulnerabilities across the software development lifecycle and to automate complex API security testing. It embeds into existing systems, is designed to meet compliance and security requirements, and integrates directly into CI/CD pipelines.

Once deployed, Equixly’s agents monitor how each application is used, infer its underlying logic, and run targeted attack simulations to identify weaknesses in a way that mirrors the behaviour of skilled attackers.

This allows Equixly to flag issues to teams in real time, helping developers and security teams remediate earlier, reduce costs and improve resilience. It can also identify deep, complex business-logic issues and edge cases, detecting hidden and emerging threats in areas traditional scanners may miss or overlook.

Equixly was among the first to draw attention to emerging risks related to Model Context Protocol (MCP) servers, and its approach is expected to become increasingly important as AI-generated code accelerates development and expands the attack surface beyond the capabilities of traditional security tools.

Equixly’s CEO and co-founder, Mattia Dalla Piazza, noted that with upcoming regulatory changes and the continued rapid expansion of APIs, the need for autonomous security solutions will only increase:

Equixly is making advanced security testing continuous, autonomous and accessible to every development and security team. With agentic AI infrastructure and models fully built in-house, teams get the human-level reasoning they need at the scale modern software demands, while ensuring maximum control over data and preserving privacy.

Equixly is trusted by a growing group of European businesses across banking, energy, insurance and retail, helping them strengthen and future-proof their systems in the face of evolving threats.

The new funding will be used to expand the team, further develop the company’s proprietary AI models and accelerate international growth, beginning with the establishment of a UK sales and marketing presence early next year.
