Rise of the bots: X.ai raises 23m more for Amy, a bot that arranges appointments

While voice-recognition-powered virtual assistants like Siri, Cortana, Google Now and Amazon's Echo continue to get more useful and reliable on the march to platform-dom, there is a parallel wave of development underway that has captured the public eye, where machine learning, artificial intelligence and natural language processing are getting corralled for more narrowly purposed means -- by way of bots. Today, a New York-based startup called X.ai -- which has developed a bot that helps you arrange meetings with other people by way of a virtual assistant ('Amy' or'Andrew') -- announced that it has raised 23 million. The Series B funding will be used to take X.ai from a closed and free beta to a commercial product, and the startup also plans to hire more data scientists and other engineers. X.ai is not releasing details of its valuation, but we understand from reliable sources that it is now around 100 million -- a decent jump on the 40 million valuation the company had when it announced its Series A of 9 million in January 2015. The funding is being led by Two Sigma Ventures, with other new investors including DCM Ventures and Work Bench Ventures.
