IInternxt
Internxt is a Valencia, Spain-based privacy technology company offering an open-source, zero-knowledge encrypted cloud storage ecosystem (Drive, Photos, Send, Mail, Meet, VPN, Antivirus) as an ethical alternative to Big Tech cloud services. Founded in 2020 (with roots back to 2017), it claims over 1 million active users, is the first cloud storage provider with post-quantum encryption, and is profitable with 100% year-over-year growth. Backed by investors including Juan Roig, Telefónica, and Prosegur, it raised a €3.3M/$3.84M Series B extension in July 2025.
