A Galway-based technology company has been sold to a US firm that specialises in retail technology software. 

Altocloud has been bought by San Francisco-based Genesys, in a deal understood to be worth several million euro. 

The Galway operation - founded by Dragon's Den investor Barry O'Sullivan - employs 26 people.  

A spokesperson for the company said there would be no impact on staff numbers or the company's presence in Galway as a result of the sale. 

Mr O'Sullivan will continue to be involved in the company, working in a consultancy role. 

Genesys said the deal strengthens its capability in artificial intelligence (AI) and machine learning.
