What it is
Sofa is a Chrome extension that syncs video playback across Netflix, YouTube, Disney+, and other platforms with built-in voice chat and text reactions, letting distributed friends watch together without screen sharing or new accounts. The product is free and prioritizes ease of entry through existing streaming subscriptions.
The one thing to knowNo monetization strategy is evident despite the founder building a frictionless social layer on top of premium streaming services, which is the primary risk to viability as a standalone venture.
