I Left You A Note started with a simple frustration: hotel guests had questions, hotels had answers, and nothing was connecting them at the right moment. Stephen O'Sullivan set out to fix that — building a platform that turns every stay into a conversation.
ILYAN was born from a straightforward observation: the most valuable moment in a hotel stay goes largely untouched. Guests arrive, they explore, they wonder — and hotels miss the chance to help, upsell, and listen because there's no frictionless way to reach them.
Stephen built ILYAN to bridge that gap. By combining QR codes and NFC technology with an AI concierge, automated upselling, and real-time ticketing, ILYAN puts a personalised hotel guide in every guest's pocket — and a powerful operations tool in every manager's hands.
What started as a concept became an award-winning platform now helping hotels across Ireland capture more revenue, resolve guest issues before they become reviews, and free up their teams to focus on the moments that matter.
