Earlier this month, payment network Dwolla announced that it raised $5 million in Series B funding from Union Square Ventures. In addition, Village Ventures, Thrive Capital, Artists & Instigators  and angel investor Paige Craig also participated in the round.

Silicon Prairie News reports:

“With the new funds, which bring Dwolla’s total amount raised to date to around $6.3 million, the company plans to bolster its product development and support and aggressively expand its API offerings…”

While not divulging any concrete numbers, Dwolla has shared a few stats over the past year on its blog: 

• Users grew 25x
• Merchants grew 37x
• Millions have been saved in fees
• 16 jobs were added to the Des Moines economy
