sundae_bar's Enterprise AI Platform Reaches Commercial Scale, Powered by SN121

Change of Name to Sundae Bar AI PLC

sundae_bar (AIM: SBAR), the Enterprise AI Platform where businesses discover, deploy and manage AI through one simple interface, today confirms that its commercial marketplace and Subnet 121 ("SN121"), its decentralised AI development network, now operate as a single integrated system.

Deploying AI remains fragmented, expensive and technically complex for most businesses. sundae_bar's premise has always been simple: businesses don't want hundreds of disconnected AI tools. They want one trusted place to access intelligent automation.

Under this model, real business demand identified on the commercial platform is converted into structured AI development challenges on SN121. A global community of developers competes to solve them, every submission is benchmarked autonomously, and the best-performing capability is deployed straight back into the commercial platform for customers to use. The Board believes this closes the loop between what customers need and what the Company builds, without a proportional increase in internal engineering headcount.

What sundae_bar Does
sundae_bar operates a commercial marketplace at sundaebar.ai through which businesses discover, deploy and manage AI Skills, AI Agents and bespoke enterprise AI solutions from a single interface. Behind that marketplace, SN121 sources, tests and rewards new AI capabilities from a global developer network on Bittensor, continuously expanding the platform's product offering.

When a customer visits the sundae_bar platform, they can browse the marketplace to select an AI Agent or Skill directly or describe what they need to sundae_bar's proprietary agent, Scout. Scout then either searches the marketplace for a matching AI Agent or Skill or composes a solution by combining relevant Skills from the Company's Skills library. Businesses shouldn't have to know which AI to use. They simply describe what they need, and Scout finds the right AI for the job.

As the Skills library continues to expand with output from SN121, this orchestration capability becomes increasingly able to deliver exactly what a customer needs, a key part of the platform's scalability.

Progress Since Admission

•   Acquired SN121 and entered the Bittensor ecosystem (June 2025)

•   Released the core AI Agent marketplace with integrated payments, launching with 200+ AI Agents (October 2025)

•   Launched the Enterprise Deployment Service, opening a direct route for businesses to commission bespoke AI deployments (February 2026)

•   Secured its first commercial enterprise contract and recognised its first revenue from an enterprise AI Agent deployment (March 2026)

•   Launched a Skills directory of 120+ reusable AI workflows (April 2026)

•   Deployed seven autonomous AI agents across its technology function, effectively doubling the size of its technology team (May 2026)

•   Reported £719,892 as revenue and other operating income for the six months to 31 March 2026 in its Interim Results

•   Diversified sundae_bar's product offering by applying learnings from 1,600+ SN121 submissions to build Crumble and Scoop, its first Company-owned agents (June 2026)

o  Crumble, an AI security review agent (in beta)

o  Scoop, an AI-powered contact-enrichment skill integrated with agent-to-agent payments

•   Completed full integration of the commercial platform and SN121 into one connected development engine, with the first Skills from SN121 challenges landing directly on the marketplace (July 2026)

Why It Matters

The Board believes the integrated model provides three advantages:

(i)         faster product development through continuous global competition rather than reliance on internal engineering resources alone;

(ii)        higher-quality AI capabilities through objective, autonomous benchmarking; and

(iii)       a self-reinforcing commercial flywheel, in which customer demand generates new SN121 challenges, better AI capabilities improve the platform, and improved products attract further customer demand.

The Board believes this is what makes Enterprise AI simple in practice: the platform absorbs the growing complexity of AI tooling, so businesses don't have to.

Change of Name

The Company also announces that it has changed its name to Sundae Bar AI PLC. The Directors believe that the addition of "AI" to the Company's name more accurately represents its activities, reinforcing its commitment to innovation and the delivery of intelligent, autonomous AI solutions.

The Company's TIDM (SBAR), ISIN (GB00BRXKJ754), SEDOL (BRXKJ75) and website (https://corporate.sundaebar.ai) remain unchanged.

Shareholders will be unaffected by the change of name, and existing share certificates should be retained and will remain valid.

Jill Kenney, Chief Executive Officer, commented:

"When we listed on AIM a year ago, our premise was simple: businesses don't want hundreds of AI tools, they want one trusted place to access intelligent automation, without needing to know which AI to use. A year on, that premise is now a live product. Our commercial platform and SN121 operate as one connected system: customer demand drives what gets built, a global developer community competes to build it, and the best-performing capabilities go straight back into the products our customers use. We've gone from a beta marketplace to a platform with paying customers and more than 500 AI Skills and Agents, all sitting behind a single simple interface. The complexity is ours to manage, not theirs, and we believe that's exactly what will make this flywheel scale. We've also added "AI" to the Company's name to more accurately represent our activities and focus on AI solutions."

Outlook

Enterprise adoption of AI is moving rapidly from experimentation into procurement. With the AI agent market projected to exceed $52 billion by 2030 (Source: MarketsandMarkets, AI Agents Market - Global Forecast to 2030) and demand increasingly concentrated on trusted, integrated platforms rather than fragmented point solutions, the Board believes sundae_bar is well positioned to capture a meaningful share of that growth.

The Board's priorities for the remainder of the financial year are to continue scaling the Company's Enterprise Offering and getting new contracts, expand the marketplace's catalogue of AI Skills and Agents, grow developer participation on SN121, further automate SN121's benchmarking and challenge-generation systems, extend the use of AI agents across the Company's own teams and functions, and maintain prudent financial management.

With a live commercial platform, an AI Skills library that compounds with every customer request, and a development engine in SN121 that adds more Skills and Agents to the commercial platform without a proportional rise in cost, the Board believes sundae_bar is entering its next phase of growth from a position of genuine operating leverage.
