Full coverage: Web Summit

Sligo native Brónagh Crowley has worked in Dublin, Amsterdam, New York, and London during her sales career for companies like Web Summit and Adyen. She has now joined UK start-up Hopin, which earned unicorn status after growing to more than $1 billion in its first year.

Every year a host of Irish tech startups descend on Web Summit to pitch, promote and seek out investment for their ideas and products. Some are freshman entrepreneurs; others are seasoned business hands. Francesca Comyn caught up with four founders in Lisbon this week.

The Lisbon conference may have become too frantic for startups to be noticed, yet despite doubts and introspection around the misuse of personal data, the event remains the epicentre of the tech world.
