- Equixly
Led · Series A · Dec 2025
Founded in 2022 by brothers Mattia and Alessio Dalla Piazza, Equixly has built a penetration-testing platform that deploys proprietary AI agents to mirror the reasoning of skilled human attackers and autonomously probe API landscapes. The system integrates into CI/CD pipelines, maps an organisation’s entire API estate and can uncover the 10–20 % of shadow endpoints companies are often unaware of. According to the company, it identifies up to 80 % more vulnerabilities than standard DAST tools while keeping false positives below 1 %, enabling security teams to focus on real issues. Customers in European banking, energy, insurance and retail sectors already rely on the product to harden their defences. The business generates revenue by offering its platform to these enterprise clients, although specific figures were not disclosed. Fresh capital from its Series A provides runway to hire additional staff, further refine its in-house AI models and begin international expansion, starting with a UK sales and marketing office. Management believes looming regulatory changes and the continued proliferation of APIs will intensify demand for its autonomous security solution.
- Apono
Participated · Series B · Nov 2025
Apono delivers a Cloud Privileged Access Platform that replaces static permissions with Zero Standing Privilege (ZSP) controls based on just-in-time and just-enough-access models. Its engine validates every request in real time, allowing enterprises to grant and revoke permissions automatically across hybrid and multi-cloud environments without slowing developers or operations. The platform is positioned for an era in which human users and autonomous AI agents operate side by side, requiring context-aware, highly scalable identity governance. Over the past year, the company reports a fourfold increase in client count, and reference customers include Intel, Hewlett Packard Enterprise, and Monday.com. Apono plans to use new capital to accelerate AI-powered access intelligence, automate policy creation, and expand go-to-market efforts in the U.S. and additional international regions while scaling its engineering and sales teams. The November 2025 Series B brings its total funding to more than $54 million, underscoring growing enterprise demand for dynamic permissioning solutions.
- Acoru
Led · Series A · Oct 2025
Founded in December 2023 by cybersecurity veterans Pablo de la Riva Ferrezuelo and David Morán, Madrid-based Acoru offers an Account Monitoring Platform that links pre-fraud signals across and between banks. The software continuously classifies both first-party and counterparty accounts, creating dynamic risk profiles that flag patterns such as clusters of micro-transactions or automated interaction behaviour. By focusing on intent and network behaviour rather than individual transactions, the platform aims to stop Authorised Push Payment fraud, scam victims, and mule accounts before funds move. A consortium model allows participating institutions to share account classifications, establishing a collective defence against AI-driven fraud. The company positions its technology to help banks comply with emerging regulations around shared scam reimbursements and enhanced reporting. Although no revenue or user figures were disclosed, the €10 million Series A funding strengthens Acoru’s balance sheet and supports further product development and market expansion.
- Exein
Participated · Series C · Jul 2025
Exein develops an embedded, hardware-agnostic cybersecurity platform that integrates runtime security directly into device firmware, allowing connected devices to detect, contain and respond to threats even when offline. The system already safeguards more than 1.5 billion devices in sectors such as energy, healthcare, defence, automotive, aerospace and industrial automation, and the company projects this figure will surpass two billion in Q1 2026. Exein’s technology supports integrity checks across supply chains and helps manufacturers comply with regulations like RED 3.3, the forthcoming EU Cyber Resilience Act and the US Cyber Trust Mark. Looking ahead, the firm plans to release next-generation protections for on-device AI and large language models, with an initial unveiling slated for RSAC 2026. The new capital will also fund a multi-transaction M&A programme in 2026 and accelerate expansion in the US and APAC. Exein has experienced a significant valuation uplift since mid-2025, reflecting rising demand for device-level security and its strengthened commercial position.
- StrikeReady
Led · Series A · Apr 2024
StrikeReady is an AI pioneer transforming how modern security teams operate with a vendor-neutral AI security operations platform. Its command center integrates with an organization’s existing security tools to unify the tech stack and centralize and operationalize security. The platform leverages AI automation to make SOC teams more efficient and effective, enabling faster, more intelligent decision-making and proactive defense. StrikeReady addresses tool sprawl and the persistent shortage of skilled security professionals that hinder incident management and response. The company plans to use its new funding to extend product leadership in AI-based SOC technology, ramp its global go-to-market team, and continue scaling infrastructure. StrikeReady announced a $12 million Series A led by 33N Ventures with participation from Hitachi Ventures, Monta Vista Capital, Brian NeSmith, and Rod Beckstrom. StrikeReady builds a cloud-native security operations and management platform that maximizes return on organizations' existing security investments by integrating, operationalizing, optimizing, and consolidating disparate security products. The platform converges AI, data and automation to accelerate incident investigation, automate response, impart knowledge, and proactively secure organizations, targeting SOC analysts, incident responders, threat intel analysts, threat hunters, red teamers and security engineers. It integrates with leading endpoint, network, cloud and intelligence products and is designed to address the cybersecurity skill gap, analyst burnout, and siloed collaboration within security teams. The company emphasizes a human-centered approach to augment defenders' productivity and close talent gaps without off-the-job training. The team is led by founders Yasir Khalid (former engineering lead and architect at FireEye) and Anurag Gurtu (former head of security product marketing at Splunk and head of technical marketing at FireEye), supported by engineers who were early hires at FireEye. In less than two years StrikeReady deployed its product at numerous large and mid-sized enterprises and government agencies in the United States and internationally. The company raised seed funding to accelerate go-to-market, expand sales, and grow its R&D team.
