80/20 OS is a platform for building and automating video sales letter (VSL) funnels. It helps businesses turn website visitors into leads and customers by combining a controlled video experience with contact capture, timed offers, follow-up emails, and performance tracking. Viewers cannot skip ahead, so the sales message is delivered in its intended order, while playback speed can remain adjustable.

Users can create a landing page or embed a funnel on an existing website, then guide each prospect into a branded video room. Purchase buttons can appear at selected moments, and viewers can resume where they left off. The platform also supports behavior-based email reminders, automatically stopping follow-ups when someone buys. Its analytics show viewing and drop-off points, email engagement, purchase timing, and sales performance, helping users identify where to improve their scripts and funnels. 80/20 OS offers four VSL formats for different sales approaches, along with video hosting and customization options such as colors, logos, thumbnails, and timed links.
