About
Eudia was founded to transform how in-house legal teams operate by applying augmented intelligence to the complex, high-stakes workflows that define corporate legal departments. The company's founders recognized that in-house counsel faced growing workloads, increasing regulatory complexity, and pressure to function more like strategic business partners — all while managing lean teams. Eudia was built to give legal teams AI-native tools that understand the specific context of their company, their contracts, and their legal obligations, rather than generic document tools repurposed for legal use.\n\nEudia's platform delivers intelligence across the full in-house legal workflow, including contract analysis, regulatory tracking, matter management, and external counsel oversight. Its augmented intelligence approach surfaces insights and flags risks rather than replacing attorney judgment, making it compatible with the accountability requirements of in-house practice. The company expanded its capabilities through strategic acquisitions, acquiring Johnson Hana and Out-House to integrate specialized legal operations expertise and outsourced legal services capacity into its platform.\n\nEudia raised a $105 million Series A in February 2025 led by General Catalyst, one of the most active investors in enterprise AI. The round validated Eudia's traction with large enterprises, and the company has since grown to serve more than 50 Fortune 500 clients. This customer base represents some of the most sophisticated and demanding in-house legal operations in the world, providing both revenue scale and a strong reference base for expansion across the Global 2000. Eudia's combination of deep legal domain specificity, acquisition-fueled capability expansion, and elite enterprise customer relationships positions it as the leading AI platform for in-house legal intelligence.
