Mix (formerly StumbleUpon)

Mix.com is a personalized content discovery and curation platform that serves as the successor to the popular web discovery tool StumbleUpon. The brand's origin is rooted in the early 2000s internet boom, evolving from a simple browser extension into a sophisticated engine that suggests articles, images, and videos based on user interests. It specializes in organized 'collections' where users can save and share content from across the web.

Technologically developed and hosted primarily in the United States, the platform relies on distributed cloud infrastructure. While the service is available globally, its core software engineering and corporate operations are centralized in North America. The brand represents a shift from the serendipity-based 'stumbling' of its predecessor to a more intentional, community-driven curation model.

Ownership of the brand remains tied to the original creators and venture capital backing that facilitated the transition from StumbleUpon to Mix. The company continues to operate as an independent entity focused on the social bookmarking niche, maintaining its headquarters in San Francisco, California.
