Mycroft secures $3.5m to scale AI security platform

Mycroft

Mycroft, a company specialising in AI-powered enterprise solutions, has officially emerged from stealth with fresh backing.

The firm has raised $3.5m in a seed funding round led by Luge Capital, with Brightspark Ventures and Graphite Ventures also participating. The round saw additional support from existing investors Ripple Ventures, Developer Capital, Antler, and BoxOne Ventures.

Founded to address the growing complexity of enterprise security, Mycroft offers an all-in-one platform designed to replace sprawling, disjointed security stacks. The company’s technology integrates with more than 250 tools and enables businesses to monitor cloud infrastructure, enforce policies, secure devices, manage incidents and prepare for audits including SOC 2, ISO 27001, GDPR, HIPAA, and FedRAMP.

Mycroft intends to use the fresh capital to expand its platform capabilities, accelerate product development and extend the reach of its agentic AI system, which it describes as a virtual CISO, GRC expert and IT/Ops team rolled into one. The firm said the funding will also help bring its automation-driven compliance and security measures to a wider customer base.

Since its launch six months ago, Mycroft has signed more than 50 customers, including Superwhisper, CoVet, Unified, Willful, Wisedocs and Weave. The platform’s appeal lies in reducing the operational burden on fast-growing teams, providing enterprise-grade protection without requiring a large in-house security function.

Mycroft CEO and co-founder Mike Kim said, “Security shouldn’t be a burden. It should be a superpower. Our goal is to give every company access to enterprise-grade security without needing a massive team. Mycroft’s AI agents don’t just automate tasks — they elevate how teams operate, helping them move faster and stay protected from day one.”

Luge Capital general partner Karim Gillani said, “Today’s fast-growing companies need robust tools to protect what they’re building. Security and compliance have evolved from manual back-office functions to front-line priorities that can shape customer experiences and brand reputation. Mycroft’s AI Security and Compliance Officer is the teammate that every company needs in order to stay safe.”
