6 terms

agentic AI technical

"strategic technology initiative in agentic AI, share key business developments"

Agentic AI refers to computer systems that can make their own decisions and take actions without needing someone to tell them what to do each time. It's like giving a robot a degree of independence to solve problems or achieve goals on its own, which matters because it could change how we work and interact with technology in everyday life.

localized inference technical

"developing localized inference and federated learning architectures to minimize data exposure"

Localized inference is the process of running an artificial intelligence model close to where the data is created—on a device or within a local network—instead of sending data to a distant cloud server. For investors this matters because it can reduce delays, lower data-transfer costs, and ease privacy or regulatory concerns (think cooking a meal at home rather than shipping ingredients to a faraway restaurant), which can affect a product’s cost, scalability and market adoption.

federated learning architectures technical

"developing localized inference and federated learning architectures to minimize data exposure"

forward-looking statements regulatory

"includes forward-looking statements within the meaning of Section 21E of the Securities Exchange Act"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

affiliate program financial

"successfully launched our affiliate program and are making significant progress in the wedding space"

privacy-first technical

"developing a privacy-first, localized agentic AI platform that enables social media and digital media platforms"

Exhibit 99.1

Myseum.AI Highlights Continuing Progress on AI Development Roadmap, Technology Advancements and Growth Initiatives in Letter to Shareholders

CEO Darin Myman highlights latest developments for privacy-first, localized agentic AI platform supporting social media platforms

Myseum.AI’s core mission is to become the trusted infrastructure layer for privacy-centric media intelligence

NEW BRUNSWICK, N.J., May 18, 2026 (GLOBE NEWSWIRE) – Myseum.AI, Inc. (Nasdaq: MYSE) (“Myseum.AI” or the “Company”), a privacy-first AI and social media technology company, today issued a shareholder letter by CEO Darin Myman detailing corporate progress, AI development, and the strategic roadmap for the “Picture Party by Myseum.AI” next-gen social sharing platform launched in January 2026.

Dear fellow shareholders,

With our recent corporate name change to Myseum.AI, I want to take a moment to reflect on our Company’s strategic technology initiative in agentic AI, share key business developments, and reveal our plans for positioning our DatChat and “Picture Party by Myseum” social media platforms to capitalize on the widespread need for content privacy and social media that solves challenges not addressed by current market offerings.

Privacy-First, Localized Agentic AI Platform

Users are currently demanding more AI powered experiences, while at the same time they increasingly distrust centralized data collection. Myseum.AI is developing a privacy-first, localized agentic AI platform that enables social media and digital media platforms to deliver intelligent photo, video, and messaging experiences without compromising user privacy. The platform allows AI models to operate locally on-device or within secure edge environments, training directly on user-owned content—including photos, videos, messages, voice notes, and media metadata—to power advanced personalization features while maintaining user control and data sovereignty.

Myseum.AI’s core mission is to become the trusted infrastructure layer for privacy-centric media intelligence.

Unlike traditional cloud AI systems that centralize sensitive user data, Myseum.AI is developing localized inference and federated learning architectures to minimize data exposure. At the same time, those architectures enable continuous enhancements to AI experiences that help users manage content and create media libraries without sacrificing privacy and control. New features for our social media platforms may include agentic media assistants that autonomously organize and curate user content for smart albums and memory creation, automate photo and video tagging, and more.

Accelerating Development with AI

Integrating Claude AI with our in-house development team has significantly accelerated our platform development. Picture Party by Myseum.AI has moved from core capability development to user experience enhancements through new features such as moderation tools, organizational tools and new experiential offerings. Additionally, we have successfully launched our affiliate program and are making significant progress in the wedding space.

Marketing

Myseum.AI recently announced the appointment of Ian Goldberg to head marketing, partnerships and monetization. Ian Goldberg is the former founder and CEO of iSport360, a youth sports technology and media company, which was acquired by Signature Athletics in 2025. In his role, Goldberg launched, scaled and monetized the youth sports content platform, reaching an audience of 3.5 million parents and coaches. An early innovator in digital marketing, Ian’s playbook uses content and storytelling to quickly and cost-effectively scale tech-enabled brands.

Patent Portfolio

Myseum’s IP portfolio now includes 20 issued patents, and several filed domestic and international patent applications. Our strong and growing intellectual property is powering our ongoing technology development and platform expansion.

Right Place, Right Time

We are currently in a time where mistrust of social media platforms and privacy concerns are growing exponentially. There is a rising dissatisfaction with how users are bombarded with advertisements and nearly blatant disregard for our privacy and how our information is used. Our team believes we are in the right place at the right time with a platform and technologies that are needed now more than ever. Most importantly, we have positioned Picture Party as much more than a privacy platform — it makes it easier, more secure and more useful to use social media on based on users’ terms. Our focus on privacy-first AI and social media puts Myseum.AI on what we see as a clear path to success for both our Company as a pioneer in privacy and social media technology, and our fellow shareholders as valued partners in our future accomplishments.

Sincerely,

Darin Myman

Chief Executive Officer
