Shark Tank’s Kevin O’Leary, “Mr. Wonderful,” Brings Star Power to Myseum’s Flagship Picture Party Platform

Legendary business “Shark” gives insight on Myseum’s lead product Picture Party

NEW BRUNSWICK, N.J., Feb. 19, 2026 (GLOBE NEWSWIRE) — Myseum, Inc. (Nasdaq: MYSE) (“Myseum” or the “Company”), a privacy-first social media and technology innovator, today announced that renowned entrepreneur and television personality Kevin O’Leary — widely known as “Mr. Wonderful” from CNBC’s Shark Tank — has created a new video highlighting the Company’s flagship app, Picture Party.

In the video, O’Leary delivers his signature direct-to-camera style while introducing Picture Party as a simple, modern solution for instantly sharing event photos in private, invite-only groups. His commentary brings mainstream visibility and recognizable business credibility to the social media platform as Myseum continues its marketing efforts for expanding consumer awareness and executing user adoption initiatives.

Much more than just a shared album, Picture Party is a complete personal and private social network with a live feed that updates instantly as guests post comments and reactions, and/or add more content. The network organizes and stores the content so the party lives on when more guests join. Picture Party’s perpetual picture archive enables the party host and partygoers to relive life’s special and most important moments at any time.

According to O’Leary, “Picture Party is perfect for sharing life as it happens.”

“Having a globally recognized business voice highlight Picture Party brings meaningful attention to the experience we’re building,” said a Darin Myman, CEO of Myseum. “The platform is designed for real-world moments, and this campaign helps introduce that simplicity and excitement to a broader audience.”

What it Does:

Picture Party makes it easier and more fun to share with the people right next to you, or anywhere in the world. It solves everyday sharing frustrations by eliminating the common headaches of modern photo sharing:

• No more passing around your phone for others to view your photos and videos.
• No more crowds gathering over your shoulder to see a clip.
• No more debating whether to text, drop, email, or tag group photos.
• No more struggling with social media privacy, data exposure, or AI training risks.

How it Works:

Picture Party lets users instantly create private, encrypted spaces, called Picture Parties, to share photos and videos in curated, personal feeds. Users can:

• Create unlimited Picture Parties.
• Invite anyone via text, QR code, or in-app invite.
• Launch a Picture Party (a timed or ongoing shared event) in under a minute.
• Add titles, comments, and reactions to posts.
• Maintain complete control over privacy, interaction settings, and who can view or contribute.

The technology underpinning Picture Party by Myseum is supported by a newly allowed U.S. patent. The patent covers the core personal and private social networking architecture behind Picture Party and represents a significant milestone in Myseum’s intellectual property strategy. Management believes the new IP is foundational to a new category of private social interaction and a key driver of long-term platform value.

Kevin O’Leary’s video was part of a sponsored promotional collaboration arranged through Cameo and will be featured across Myseum’s social channels, digital marketing campaigns, and investor-facing materials as the Company continues to scale brand visibility.

Myseum remains focused on delivering secure, user-controlled social technologies while leveraging strategic promotional partnerships to accelerate growth and engagement across its ecosystem.
