Xero says interest from the US market helped bolster its share price to an all-time high last week.
Stock in the online accounting software firm rose to $10.80, just a year after its record low of $3.07.
In a notice to the stock market about the rise, Xero said its appointment of a former Google executive, US media interest and roadshows in Australia helped boost its international profile.
Chief executive Rod Drury says Xero has not yet decided whether it will list in the United States but has been advised it needs to make at least $US100 million of revenue before considering a listing.
He said the company made $NZ19 million in revenue last year and aims to double that this year.
