Tallan

Tallan was a Hartford, Connecticut technology consultancy, founded in 1985, that built custom Microsoft- and Azure-powered solutions — application modernization, e-commerce and web development, user experience, mobile, cloud, data, and AI/ML — for clients in manufacturing, consumer packaged goods, pharma, healthcare, and state and local government. In February 2023 Tallan was acquired by EY US and folded into EY's Microsoft services group; the tallan.com domain now 301-redirects to EY's Microsoft alliance page. Tallan operated as a professional-services consultancy and never published a public API, developer portal, SDKs, or event surface, so there is no API to enrich.

Tallan is profiled on the APIs.io network. Tagged areas include Company, Consulting, Microsoft, Azure, and Cloud.
