Jade develops software for the logistics sectors and works with major port and rail operators in Europe, the Middle East, North America and New Zealand.

He says 95% of the company's development work is carried out in New Zealand.
Jade Software employs 352 staff, has offices in Britain, the United States, Australia and New Zealand and turns over about $50 million a year.
