Attio offers 3rd party storage integrations with a total 1st party feel.
How it Works
Multiple provider support: Connect Dropbox, Box, Google Drive, and OneDrive accounts to Attio. Sync as many accounts as needed and move files across providers
Flexible folder structure: Whatever folder structure works for your team, you'll be able to implement
Permissions aware: Attio users with access to file folders in the original provider (Dropbox, Box, Google Drive etc.) will be able to view the same files in your workspace.
