For the borrower, the minimum sum to be raised is $100,000. The borrower needs to have at least one year of audited financial statements. MoolahSense would also conduct some level of background checks. For the investor, a minimum loan offered is $1,000. Only Singaporean residents are accepted as investors.
There are of course no guarantees. Such loans from small-medium enterprise (SME) can fold up if the company go belly up, hence the high rate of interest offered. I view such loans as similar to junk bonds.
MoolahSense appears to have only started business not so long ago. There may have been only one campaign that has taken place and it may be facing difficulty getting more borrowers interested to come on board. Nonetheless, it has been extremely active in promoting their P2P platform at many events, and has even gone on to live TV such as CNBC.
Separately, SGX also appears to be working with a partner to develop the crowd funding market. Perhaps the scene will get livelier in time to come. Not sure if this option would be available to the retail investor though.
