Entrecard acquired by Ziprunner

Banner exchange service Entrecard has been acquired by Ziprunner for an undislosed sum.

Entrecard is a popular ad swapping service in the marketing blog community. Users gain credits for ads displayed which can then be used to advertise on other sites in the community.

Entercard went on the market in September 2008 in what many considered was an attention ploy (the sale was eventually canceled.) The price asked for then was $1 million, although its difficult to tell nearly a year later whether it would have attracted a similar figure now.

Allen Stern at Centernetworks writes that founder Graham Langdon will remain on as an advisor to Entrecard, and the sale is being pitched as making the site a more “reliable and stable service” that will offer “great new features and strategic direction.”
