Shares of Myseum, Inc. (NASDAQ:MYSE) surged 100% in after-hours trading Wednesday after the company announced it will rebrand as Myseum.AI, Inc. The company said the new name, effective April 15, 2026, is intended to reflect its strategic emphasis on embedding proprietary artificial intelligence into its secure messaging and social media offerings.
Myseum described itself as a privacy-first social media and technology company and said the name change signals a shift to emphasize its AI capabilities while retaining a focus on secure digital media. Management confirmed that the company’s shares will remain listed on Nasdaq under the existing ticker symbol "MYSE."
In its announcement, the company said it is developing what it described as privacy-first, agentic localized AI agents to assist users in organizing and managing personal media - including photos, videos and messages - while maintaining privacy protections. According to the company statement, that technology adapts to individual patterns and preferences and relies on data integrity and encryption measures to ensure user information is not shared with other social platforms.
Commenting on the rebrand, Darin Myman, CEO of Myseum, said: "As a privacy-first AI and social media technology company, we continue to deliver on our commitment to innovation in the secure digital media space through our development of popular privacy-first user platforms. Our new name, Myseum.AI, identifies our core AI-based technology that secures our multi-tiered social media ecosystem."
The company also stated that its personalized AI assistant is designed to learn from individual user actions without sharing that information with traditional AI models.
