Encrypted Cloud Storage Vault

Users storing sensitive files in the cloud risk data breaches and privacy violations. A simple encrypted file storage solution that keeps files encrypted end-to-end with support for FIDO2 keys and biometric auth, accessible from any device. Target: Privacy-conscious individuals, businesses, remote teams.

Post-Snowden privacy awareness combined with recent high-profile breaches at Dropbox and LastPass has kept zero-knowledge storage in the cultural conversation, and FIDO2 adoption is finally mainstream enough that hardware key support feels like a feature rather than a friction point. Proton Drive is the obvious incumbent here, and it's well-funded, well-trusted, and already ticking the end-to-end encryption and cross-device boxes — competing on features alone is a losing game. The $5k–20k/mo revenue band is plausible only if you carve out a specific niche like HIPAA-adjacent small businesses or legal teams, where willingness to pay is higher and Proton's consumer positioning is a weak fit. The most likely failure mode is that privacy-conscious users are also the most skeptical about trusting a new, unaudited service with their sensitive files, making trust-building slow and CAC punishingly high relative to the revenue band.
