Andera Inc., the online banking and account software provider, signed its 300th customer earlier this month, marking another milestone for a firm started while its founder was still a Brown University student.

“Our entire team is deservedly psyched and should be really proud of what we’re accomplishing,” Andera founder and CEO Charlie Kroll wrote on his blog. He did not disclose the identity of the 300th customer. The company reached 100 clients in 2006, three years after signing its first customer, and 200 clients last year.
