The Opportunity

Problem

Remote workers in manufacturing struggle with clunky CAD collaboration tools that fail to sync reliably across distributed teams.

Solution

CadRelay automatically syncs CAD files across distributed teams with delta updates to minimize bandwidth and handle conflicts intelligently. It provides real-time notifications and presence indicators so engineers know who's editing what. Built for reliability, it ensures no lost changes even on spotty connections.

Target Audience

Remote engineers and designers in manufacturing companies using CAD software for distributed team collaboration

Differentiator

Lightweight delta-sync engine optimized for large CAD files, reducing sync times by 80% compared to full-file uploads
