Jellyfish launched the first beta version of service in June 2006, after receiving an initial seed round of investment from its founders, Brian Wiegand and Mark McGuire, and Kegonsa Capital Partners.[4]

In a press release, Kegonsa Capital Partners said that it acquired 25 percent of's stock for about $600,000 in February 2006, and made 15 times its seed investment with the deal.[5]

On October 2006, Jellyfish raised an additional 5 million dollars in funding.

It was expected to have 20 employees by the end of October 2006, at the Old Sauk Trails business park, on the Far West Side.[4]

Kegonsa, a Fitchburg, Wisconsin group with 42 Wisconsin investors, led the second round of investment on October 2006,[6] with more than $1 million in October 2006 through the Kegonsa Co-Invest fund, for a total of $5 million.[7][8] The second round investors more than doubled their investment in less than a year.[5]

In an interview in July 2007, Wiegand said Jellyfish had sold nearly $5 million worth of products, "everything from bicycles to shoes".[6]

McGuire explained that the name Jellyfish was chosen because they wanted to be completely transparent.[9]
