But Gingrich's organization, American Solutions for Winning the Future, is incorporated as a 527 group, and is not subject to the same contribution limits as political action committees - the type of organizations most politicians spearhead, including fellow potential presidential hopefuls Mitt Romney, Sarah Palin, and Mike Huckabee.
Unlike PACs, 527s can also directly accept funds from corporations but is barred from directly contributing to a candidate or financing a potential White House bid.
Dan Kotman, the spokesman for American Solutions, said Gingrich was only "one part of the fundraising process."
"He played a role as our general chairman, but there were a lot of other factors," Kotman said.
The organization, with a staff of nearly 20, bills itself on its Web site as "a unique tri-partisan organization designed to rise above traditional gridlocked partisanship."
But it also largely operates as a promotional vehicle for Gingrich himself, regularly dispersing e-mails advocating the former House Speaker's positions on issues, advertising his books, and financing his travel across the country to the tune of nearly $700,000 in the first half of the year, according to a report filed with the IRS.
In contrast, the political action committees of Mitt Romney, Sarah Palin, and Mike Huckabee, each reported raised $1.6 million, $730,000, and $300,000 respectively.
