We look back at the seven biggest stories of the week, including a social media ban for young people in the UK, ChatGPT’s move into advertising, and the billionaire Twitter spat we didn't know we wanted. We also explore the arrival of SEPA Instant in Ireland and what it means for neobanks like Revolut.

Plus, our guest Fergal Brosnan, CEO of RDI Hub, fills us in on the importance of the "cluster effect" for start-ups and how Kerry is becoming a focal point for fermenting new tech ideas.
