Conor Lyden
Conor Lyden is the founder and CEO of Trustap, a Cork-born fintech that embeds escrow-style payment protection into online marketplaces so strangers can buy and sell without getting scammed. He came up with the idea at 21 as an engineering student at University College Cork, frustrated by the risk of buying football tickets from strangers, and built the concept through UCC's Ignite incubator. Since founding the company in 2016/2017, he has grown it into a global operation with offices in Cork, Dublin, London, Barcelona, Zagreb and New York, serving over 250 marketplaces across more than 100 countries and raising a $5.5m Series A led by TX Ventures.
Trustap
Trustap is an Irish fintech that provides escrow-style, milestone-based payment infrastructure for online marketplaces, ecommerce platforms and individuals.

Founded in Cork in 2017 by Conor Lyden after he was scammed buying football tickets, the company now works with 250+ partners across roughly 27 countries and is building Trustap Index, a product that makes marketplace listings machine-readable and transactable by AI shopping agents.
