Software firms from across the globe are gathering again today in Belfast for the EnterConf event in the Titanic Quarter.
And while some travelled from tech hubs such as Silicon Valley, others are visiting the city from more remote areas of the world.
Luis Cabral de Melo is from the Azores and runs his firm Cybermap, which utilises digital maps to develop software and analyse data. It started up 15 years ago and now boasts a workforce of 20 people.
Meanwhile, French and US-based software firm Algolia has raised some $20m (£12.5m) in capital since it formed back in 2012.
The firm's Gaetan Gachet said the software allows companies and websites to have a "Google-like search experience" within their own site.
It now employs 24 staff.
"We allow developers to develop inside their website or mobile application, a Google-like search experience. For the end user, it means finding answers as you type. It's very fluid and seamless."
Elsewhere at EnterConf, Dublin-artificial intelligence firm Aylien was also showing off its technology.
The company was started in Iran, before its founder Parsa Ghaffari moved to Ireland and set up shop in Dublin.
Mike Waldron, who's behind marketing sales for the firm, said: "We are an art intelligence and machine learning company. We focus on text analysis and image analysis."
EnterConf is a spin-off from the Web Summit in Dublin, and a sister event to MoneyConf, which took place at the same venue earlier this week.
And it's set to draw speakers from some of the world's biggest technology companies when it returns to T13 today.
That includes Thomas Davies of Google and BT's chief technology officer Colin Bannon.
