Share confidential materials, and keep control of them.
Selo is a self-hosted, sovereignty-first portal for sharing sensitive documents with named recipients: investor raises, donor diligence, grant applications, and board or partner sharing. A boutique, in-jurisdiction alternative to commercial data rooms, built by OpenImpact Studio.
Have an access code? Open your space.
-
Per-recipient access
Each named recipient enters a one-time access code. Issue, scope, expire or revoke them individually, and tie every view to a person.
-
Tiered, gated access
Open, gated and agreement-gated tiers, enforced on the server. Restricted material unlocks only after the recipient accepts your agreement.
-
Watermarked and tracked
Every page is watermarked with the viewer's identity, burned into the file, and every open is logged for a full audit trail and engagement analytics.
-
Sovereign and white-label
Self-hosted in your own jurisdiction. Run many isolated spaces and tenants, each white-labelled with its own brand.
Selo, the Portuguese word for a wax seal: the mark of something sealed, secure and trusted.
