HourlyNerd, a Boston-based online staffing platform, closed a $22 million Series C funding round. The new funding will be directed towards further development of HourlyNerd’s software solutions and market education.

General Catalyst Partners led the funding round, with participation from Highland Capital Partners, GE Ventures, Mark Cuban, Greylock Partners and Bob Doris of Accanto Partners. The new funding round brings HourlyNerd’s total amount raised to more than $33 million.

“This is a tipping point for our business,” said Rob Biederman, co-CEO and co-founder. “Top professionals are choosing to be independent: controlling where, when and how they do business. When we started in 2013, we believed that talent should be able to find opportunity in a radically different way. To gather such momentum so quickly has been rewarding and speaks to a massive market opportunity; we're only scratching the surface. Talented people will gain even more freedom and flexibility in coming years, and we're excited to help drive that transition.”

HourlyNerd’s user base includes a network of 25,000 business expert suppliers serving 5,000 companies worldwide, including nearly 10% of the Fortune 1000, according to the company.
