Peer-to-peer crowdlending platform P2Binvestor (P2Bi) received more than $17 million in combined debt and equity funding this week. The debt investment come from more than 20 participants, all sourced from the P2Bi marketplace that consists of banks, private investors, and institutional investors. The equity funds come from Angel investors.

The Colorado-based startup has not disclosed the breakdown of debt vs. equity but we estimate around $13.4 million of the total is debt and about $3.6 million is equity. This is based on P2Bi’s report that today’s investment is its fourth round of equity funding, bringing its total equity raised to $13 million. While the company did not comment on its total funding, Crunchbase estimates P2Bi’s combined debt and equity at $33.76 million.

P2Bi will use the funds to power its new bank partnership program. Launched last year, the bank partnership program offers access to working capital to small-to-medium businesses (SMBs) who don’t qualify for traditional financing. It not only allows banks to invest in local businesses, but also helps them tap into a new asset class. Under the partnership, banks will front 50% of the capital with a senior secured position. P2Bi’s base of private investors will provide the remaining half of the capital and businesses will receive the funds with a blended interest rate of 8% to 12%. New Resource Bank, which began piloting the bank partnership program last October, has already closed seven loans worth over $16 million.

“Over the course of the past few months, P2Bi has focused on building a new partnership model with community banks that is proving to be very successful,” said Krista Morgan, CEO and cofounder of P2Binvestor. “Growing businesses love the idea that we can graduate them to cheaper financing without the hassle of switching, and banks love that they can be the first lender to a growing business building a valuable, long-term relationship. This raise enables us to onboard new banks into the program.”

Founded in 2012, P2Bi debuted at FinovateSpring 2013 and showcased its borrower application and loan management platform at FinovateFall 2014. Earlier this spring, MonJa featured Morgan in an interview and last fall the company made Credit Donkey’s list of Best Finance Technology.
