Siilo Holding

Siilo is a digital health company that built a secure, compliant messaging and collaboration platform for healthcare professionals and care teams. The product enables physicians, nurses, and healthcare organizations to communicate about patient care, share medical knowledge, and coordinate workflows in a privacy-conscious environment designed for clinical use. Founded in the Netherlands, Siilo grew into one of Europe’s best-known medical messaging networks before being acquired by Doctolib in 2023. Following the acquisition, the product has been transitioned under the Doctolib Connect brand, while continuing to serve healthcare professionals with secure communication and organizational collaboration tools. Siilo is not a therapeutics developer; it is a commercial healthcare software and platform business.
