Niall Dennehy's first bank account was opened in 1987, when his mother walked him ten metres from their front door to the credit union in Ballydesmond, Co. Cork — a branch named for Nora Herlihy, the local schoolteacher who helped found the Irish credit union movement. He still gets the statement every month. Nearly four decades on, having co-founded blockchain company AID:Tech and gone through Techstars, he's a father of four in Dublin building NestiFi: an AI-powered platform that lets whole families, wherever they've scattered, invest together in a child's future.In this conversation, we get into:The 1987 credit union account Niall still gets statements for, and how it became the blueprint for NestiFiWhy the cash-stuffed-envelope economy shortchanges kids, and how a tap in the family WhatsApp chat can put relatives anywhere in the world into a child's investment accountThe tax reliefs most Irish parents have never heard of, including the small gift exemption worth up to €108,000 per child over 18 years from parents aloneTrump accounts in the US, and Niall's lobbying push to get the Irish government to seed every newborn's account the same wayWhat 1–2% in annual fees quietly does to 30 years of compounding, and why credit unions are best placed to win back the next generation from Revolut and RobinhoodIf you're a parent, a grandparent, or anyone thinking about the next generation's financial future, this episode is a practical look at how families can start compounding early.$84 trillion is expected to change hands in the US over the next 20 years; roughly €3.5 trillion in Europe by 2030 (figures Niall cites on tape).$2,500 seeded at birth plus $75/month from the wider family ≈ $40,000 by age 18 and $106,871 by age 30 (NestiFi's illustration; assumes a 7.35% average annual return compounded monthly).Niall Dennehy is the CEO and co-founder of NestiFi.
