CentralNic saw a huge 171% increase in revenue and a tripling of billings in the first half of the year, based on its newly acquired retail business and the sale of premium names.
For the six months to the end of June, the London-based firm saw revenue of £4.4 million ($6.8 million) compared to £1.6 million ($2.5 million) a year earlier.
It moved into profit during the period, netting £287,000 ($442,000) after tax compared to a loss of £599,000 in the 2014 period.
CentralNic broke down its numbers into segments, showing that its new business areas were responsible for most of the growth, while the core registry business was relatively slow.
Registry was up 13% to £1.6 million ($2.5 million).
The new registrar business, which is lead by its $7.5 million Internet.bs acquisition, leaped from £180,000 to £1.8 million (£2.8 million), while its premium name sales business was £1.1 million compared to a negligible £50,000 a year earlier.
The company noted in a statement that Google was the first “megabrand” to use a .xyz domain name and expressed optimism that this may increase awareness of new gTLDs in future.
CentralNic is the second-largest new gTLD back-end, as measured by registration volume, largely due to its .xyz contract.
It also acts as back-end for .online, which left the blocks very quickly earlier this month, racking up over 57,000 names so far.
