Rencore

Rencore builds what it calls a governance operating system for Microsoft 365 — a platform that automates security, compliance, and risk controls across Teams, SharePoint, OneDrive, Entra ID, Exchange, Viva Engage, and the Power Platform. The underlying problem is one every large Microsoft-centric enterprise runs into: as employees spin up thousands of Teams, SharePoint sites, and Power Platform apps, manually enforcing naming conventions, external-sharing restrictions, sensitivity labeling, and lifecycle policies at that scale becomes impossible, and native Microsoft admin tooling wasn’t built to do it continuously and automatically across a large tenant.

Rencore has extended that governance model into a newer and more urgent risk area: Microsoft Copilot and enterprise AI agents. As organizations roll out Copilot across a tenant with years of accumulated (and often over-permissioned) SharePoint and Teams content, that legacy oversharing becomes directly exploitable by an AI assistant that can now surface and summarize anything a user technically has access to, even if no one intended that access to be used that way. Rencore’s governance layer is positioned to catch and remediate that kind of latent access-control debt before Copilot or autonomous agents expose it.

Founded in 2013 and based in Munich, Rencore has grown to roughly 500 customers, including large enterprises like Microsoft, Barclays, Vodafone, Siemens, and Merck, and reported around $10.5 million in revenue in 2024. The company raised a Series A extension to $15 million in late 2025, led by Hi Inov with continued participation from UVC Partners and Capnamic Ventures, earmarked for international expansion and further AI-governance development. That funding level and 500-customer base put Rencore in a credible but still mid-market position relative to larger enterprise GRC and cloud security posture management platforms.
