Financial services company American Express on Tuesday announced a 100 million-U.S. dollar investment plan to fund early stage digital commerce startups, as part of a multi-year initiative designed to help accelerate the company\'s digital transformation. In a press release, the company said that the digital commerce initiative will be managed out of its newly established office in Silicon Valley. \"The payment industry is undergoing a fundamental change as the very nature of commerce is redefined,\" said Harshul Sanghi, the company\'s vice president of the Enterprise Growth Group and director of the new Silicon Valley office. The digital commerce initiative will look to make investments in companies focused on serving critical parts of the digital commerce experience, including loyalty and rewards, mobile and online payment management, fee-based services, security and fraud detection and data analysis, said the company.
