But there are online lending sources that do make small loans ($25,000 or so) to small businesses, including Prosper.com, Zopa Inc., GlobeFunder Ventures Inc., Virgin Money USA and Lending Club.
The State of Oregon manages the Entrepreneur Development Loan Fund (EDPL) which loans up to $25,000 to entrepreneurs who are taking advantage of a certified business planning organization (e.g., an SBDC or OTBC).
