In the 1990s, Calacanis began his career as a New York-based reporter covering the internet sector. On September 24, 2003, Calacanis and Brian Alvey co-founded the blog network Weblogs, Inc. Mark Cuban made an angel investment in the company. The Weblogs, Inc. blogs company was bringing in $1,000 per day from AdSense barely two years after its launch. In October 2005, Time Warner's America Online agreed to purchase Weblogs, Inc. for $25–$30 million.

In may 2007 he founded the web directory Mahalo, which means "thank you" in Hawaiian. Sequoia Capital, News Corp., CBS, Mark Cuban, and Elon Musk were among the investors that contributed $20 million to the project. In 2011, the business reached a monthly peak of 15 million unique visits and turned a profit, but the Google Panda search algorithm upgrade caused a significant drop in traffic that year, and it was forced to close in 2014.
