Here are my 2-cents thoughts. As much as p2p is a tech driven fintech, it is still a service industry nevertheless. To me, whatever technology features such as auto-invest will soon be commonly used by the platforms. Without them, they will lose an edge. So you could start by asking yourself what would you like to have as an investor or a borrower. For a borrower, would be probably necessary financial advice so that they will get sufficient funds. Etc. For an investor, you want as lower risk loan as possible. Is there a sufficient supply of loans? Which platform provides a better investing experience? the extensiveness of platform providing the loans. How receptive are the platform to feedback and their responsiveness in changes? Having a good customer base, along with a good support team could improve your rewards and user experience. Furthermore, having 0% default rate is ideal. However, is your funds put into desirable rewards investment? This also questions the response of the platform in a situation of defaults. In choosing the platform, ask yourself what gives you a better piece of mind. Is it within your risk-reward? Which loan product do you prefer? (there is some difference in loans offered among the platform) what is your ability? (your fund size and risk tolerance ). You should also filter the reviews and forums of the platform. Remember this is a service industry. In my opinion, a good service, or user experience should be the main factors in choosing the platform. A good service attracts more borrowers and in turn attracts more investors. A good service is what drives the platform to innovate and constant improve themselves. Do your due diligence.
