Prototype and Pre-Launch Work Sharing Platform with Built-In NDA and Access Revocation

saas real project • single request

Designers and founders sharing early-stage work need instant NDA generation, versioned audit trails, and one-click access revocation. Current workflow involves emailing NDAs, waiting for signatures, then sharing via Google Drive with manual permission management. An HN developer is building ProtoWall for exactly this, validating that the demand is real enough to motivate a builder.

The wedge is the magic link experience. Nobody wants to install an app to view a prototype. Make it feel like sharing a Loom link but with legal protection baked in. Charge per-project not per-seat since founders' sharing needs are bursty. The legal layer is the moat since competitors would need to handle NDA templates across jurisdictions.

The pieces exist separately (NDA tools, secure sharing tools, access management) but nobody has unified them into a single flow: share link → recipient signs auto-generated NDA → gets time-limited access → all activity logged → one-click revoke. The market is founders, designers, and agencies in the pre-launch phase.

DocSend Document sharing with analytics but no NDA layer, no legal audit trail, and designed for fundraising decks not general pre-launch sharing

Google Drive + DocuSign Requires stitching together two separate tools manually. No unified workflow, no automatic NDA versioning, clunky permission revocation

Digify Secure document sharing with NDAs but enterprise-priced and complex. Not designed for indie founders sharing a prototype with 3 beta testers
