Realm is an AI-powered cybersecurity company building a security data pipeline platform: it sits between security data sources and downstream tools, letting security operations teams filter, enrich, and route telemetry so their SIEM and detection stack stay fast and affordable.
The company was founded by Pete Martin, who raised its $5 million seed round at a $25 million post-money valuation in 2024 and closed a Series A in late 2025.
As AI agents expand the enterprise attack surface, Realm's pitch is that the security data layer - what gets collected, kept, and analyzed - is where AI can compound defenders' leverage the most.
