A business model for yet another fintech style operation, aimed at stealing a few more pieces of the banking sector's lunch, is being developed by an ex-Goldman Sachs banker.Presenting at an Alternative Investment Management Association lunchtime seminar in Sydney yesterday, Steven Sher, co-founder of Global Credit Investments, said his firm was developing a credit fund focused on generating stable income through the acquisition of high quality short-duration credit assets.Sher added that the declining cost of technology was leaving the way open for "specialty lenders" to "pick off pieces" of banks' balance sheets.In this regard, credit has historically been largely inaccessible to non-bank investors, but technology has caught up to the market, allowing investors such as GCI to acquire credit that historically sat on a bank's balance sheet. His firm uses proprietary algorithms to assess and acquire consumer loans in the US and will soon be adding short-term US real estate credit to the fund, Sher said. It is "an old way of lending, done in a very new way" with implications for the smaller end of retail lending.
