zipMoney may light a path into the debt capital markets for fintech financiers, if a warehouse funding line from a major bank turns out to be a precursor of further asset-backed funding.While zipMoney did not name the bank, its managing director, Larry Diamond, pointed to one commercial benefit of the bank tie up, expected in coming months, that "will approximately halve the weighted average cost of capital of our loan book, which directly contributes to our bottom line."Short-term or revolving consumer loans are a rare asset class in asset-backed deals in the Australian capital market, with Flexigroup the only real benchmark. The bank loan will ultimately allow zipMoney to cut its reliance on a facility from US hedge fund Victory Park Capital that comes with much higher rates.One of a range of fintechs crowding the more traditional "pay later" point of sale segment (while seeking online merchants only), zipMoney yesterday took its turn this profit season to outline mostly bright business metrics, while also owning up to a loss.It's loss of A$5.9 million for the half year to December 2016 is around twice the loss over the same period in 2015.But customer acquisition - which Diamond put at between 1000 to 2000 a day - may support a turn about in line with a vision to fit alongside, if not displace, more traditional pay later options such as bank issued credit cards or Latitude.zipMoney said transaction volume for the half was $83.2 million, an eight-fold rise, while the loan book was $88 million, around ten times the size.zipMoney said it has "more than 160,000 customers and 2700 merchants" and a growth story now with the weight of a big bank name behind it.
