"These guys sell over 150 different countries, so they are one of only a handful of companies anywhere in the world. It can benefit large companies that are launching a new product and want to make sure their product name gets registered it in every country in the world, to stop other people registering it."
Emerging markets were where most growth for domain-name registration companies existed, but they also required a breadth of nations covered.
"If you want to enter one of these big emerging markets like China, Indonesia, Turkey and Brazil you have to have the local product that they want and plus they are always interested in the neighbouring countries, for example the New Zealand company would probably quite like to get the same domain name in Australia to cover it off.
"For us Instra Corp is already a proven winning combination to actually enter all of these emerging markets and to serve international companies as well, so were very keen on them."
Instra is based in the bottom floor of the Public Trust Office building in Tennyson St, where 32 staff work 24/7.
Ms Jameson credits New Zealand operations manager Louise Lentino with Instra's success.
She is the sister of former Instra owner Tony Lentino and established the office 18 years ago.
Mr Crawford said the Melbourne office of 20 people, which concentrates on technical developments, would also grow staff numbers.
