SMU graduates Max Xu, Carylyne Chan and Spencer Yang were featured in a Straits Times article about Singapore start-ups in San Francisco. Co-founders of KeyReply, their firm designs artificial-intelligence chatbots for online service providers. The bots respond to customer chat enquiries and requests, and can be deployed on commonly used messaging services. The trio started out developing their software in Singapore before being accepted into an accelerator programme in Hawaii and eventually moving to Block 71 San Francisco. Mr Yang noted that they moved out of Singapore back then because the Singapore ecosystem for software was still developing and it made more sense for them to tap on the networks in San Francisco. He added that the company is recording revenue of about US$1,000 (S$1,340) per month and aims to further expand its client base.
