Founded in 2009 by eCommerce entrepreneurs, Daniel Jarosch and Rolf Weber, brandsExclusive is on track to produce sales of A$70 million this calendar year, APN said. Jarosch is the company's co-managing director.
The website has more than 1.8 million members and is adding about 70,000 a month, resulting in the business being included in the BRW Fast Starters list for 2012, APN said.
"We believe there is tremendous value to be unlocked in the global shift towards eCommerce which will be a core part of the digital media landscape in the future," chief executive Brett Chenoweth said.
Like its rivals Fairfax Media and News, APN has been grappling with an evolving media industry which has seen advertising revenue from newspapers ebb as more consumers turn to the internet for their news.
Last month APN appointed Deutsche Bank to undertake a strategic review of its media assets in New Zealand after receiving approaches from potential buyers.
Shares of APN last traded at 73.5 Australian cents on the ASX and are little changed this year.
