Liam Fuller AI: Irish Teen’s $1.4M Startup Redefines Retail Procurement

In a world where artificial intelligence is reshaping industries, one name stands out: Liam Fuller AI.

At just 18, this Irish prodigy has ignited a revolution with his startup, Source, securing an astonishing $1.4 million (€1.2 million) in pre-seed funding on July 23, 2025. Led by Australian venture capital titan Square Peg Capital, this funding round marks a seismic moment for the Liam Fuller AI narrative, heralding a new chapter in retail procurement automation. This blog dives into Fuller’s extraordinary journey and his vision for Sourcem.

From Dublin Schoolboy to AI Visionary

Born in Dublin, Ireland, Liam Fuller’s entrepreneurial spark ignited at age 14, when he began crafting Shopify apps and experimenting with large language models. By 2024, at just 17, he and his colleague Joseph Mudrak clinched the prestigious Regeneron Award at the BT Young Scientist & Technology Exhibition for their project, “Your Dynamic AI Voice Companion – Redefining Personal Assistance.” But it was a viral LinkedIn post—showing Fuller taking a business call from his school bathroom—that thrust him into the global spotlight, leading to a school suspension and his bold decision to drop out and pursue Liam Fuller AI ventures full-time.

Fuller’s audacity paid off. While visiting family in Australia in March 2025, he cold-emailed Square Peg co-founder Paul Bassat, securing a meeting in Sydney the next day. Weeks later, Bassat led a $1.4 million funding round, joined by heavyweights like former Stripe CTO David Singleton, Eucalyptus co-founder Charlie Gearside, and the Xtripe angel syndicate. “I’ve been impressed by many young entrepreneurs, but Liam combines technical sophistication with commercial instincts that are rare at any age,” Bassat said, cementing Fuller’s status as Square Peg’s youngest portfolio founder.

Source: The AI Revolution in Retail Procurement

At the heart of Liam Fuller AI is Source, a groundbreaking platform that leverages agentic AI to automate retail procurement. Fuller identified a glaring inefficiency: many retailers still rely on email and Excel to manage millions in stock purchases weekly. Source integrates with email, point-of-sale systems, and Enterprise Resource Planning (ERP) tools to analyze inventory and sales data, generating AI-driven purchase orders that humans can review with a single click. This innovation slashes administrative hours by up to 80%, keeping shelves stocked and freeing retailers to focus on growth. Tech.eu

“I was shocked to find that most businesses, especially retailers, still rely on email and Excel to buy hundreds of thousands of dollars’ worth of stock every week,” Fuller said. Source’s intuitive interface empowers retailers managing thousands of SKUs, offering a seamless, modern solution to a decades-old problem. With nearly ten pilot programs already underway, Source is poised to disrupt the $44 trillion global retail market. Silicon Republic
