An AI startup co-founded by Irish 18-year-old Liam Fuller has secured €1.2 million in pre-seed funding.
Mr Fuller’s company, Source, is a platform that automates stock purchasing for retailers using agentic AI.
The funding round was led by Australian VC Square Peg, alongside former Stripe CTO David Singleton and the Xtripe angel syndicate.
Mr Fuller is the CEO and co-founder of Source and is Square Peg’s youngest portfolio founder to date.
He has now left school to build Source full-time.
“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,” Mr Fuller said.
“Source provides a simple interface allowing retail buyers to understand what they should buy and when by integrating into Excel, email and ERPs (Enterprise Resource Planning).”
“Source scans inventory and past sales data to generate forecasts and suggest purchase orders with AI that humans can edit and approve with a single click,” he added.
While visiting family in Australia last April, Mr Fuller secured a meeting with Square Peg co-founder Paul Bassat, and closed the funding round within weeks.
“I’ve been impressed by many young entrepreneurs, but Liam combines technical sophistication with commercial instincts that are rare at any age,” Mr Bassat said.
“When someone demonstrates this level of execution and strategic thinking at seventeen, the growth trajectory becomes incredibly compelling,” he added.
The capital will be used to double engineering headcount, launch US pilot programmes this autumn and finance a Silicon Valley relocation later this year.
In parallel, Source has joined the NDRC Accelerator, operated by Dogpatch Labs in Dublin.
