Belfast software company Kainos - one of just two plcs in Northern Ireland - is joining the Prime Minister on her first trade mission to India.
The firm, which is led by Brendan Mooney, was selected to join Theresa May on her three-day trade mission.
The company develops digital technology for public and private sector organisations. Being included in the India mission is the latest honour for the firm, after its managing director Brendan Mooney was named EY Entrepreneur of the Year in the all-island competition.
Kainos is part of a delegation led by Theresa May to showcase the UK's small and medium sized companies to Indian investors.
Prime Minister Theresa May said: "I'm pleased that Kainos will be joining me on this important trade mission to India.
"Kainos is an excellent example of the kind of company which is not only boosting Northern Ireland's economy but the whole of the UK's - making this a country which works for everyone.
"Their innovative technology and entrepreneurial spirit is an asset to Northern Ireland, which remains one of the most popular destinations in the UK for foreign direct investment outside of London."
Brian Gannon, Kainos corporate development director, said: "As a leading participant in the UK's fast-growing digital economy, Kainos is delighted to help showcase our advanced hi-tech skills and know-how around the globe."
Kainos is joining 38 other small and medium sized firms in seeking new business on the trip to one of the world's biggest economies. The visit will include South Asia's largest tech fair.
The UK-India TECH Summit will be hosted in New Delhi by the Prime Minister and her Indian counterpart. It is designed to help boost hi-tech trade between India and the UK. The trip is part of efforts by May to project a new vision for the UK after Brexit. A statement from Number 10 said she would be "forging a new global role for the UK as a country with the self-confidence and the freedom to look beyond the continent of Europe".
