The founder of a startup acquired by Amazon for a reported 26 million is now investing in AI

A Cambridge entrepreneur who sold his company to Amazon is increasing the amount of angel investing he's doing now he no longer works for the e-commerce giant. William Tunstall-Pedoe sold Evi Technologies, his voice recognition startup to Amazon in 2012, for an undisclosed amount that TechCrunch reported to be around 26 million ( 20 million). Following the acquisition, Tunstall-Pedoe became part of the Amazon family. However, his investment activities have been somewhat limited over the last four years. "I did a bit of investment while I was in Amazon but obviously that was constrained by Amazon legal; I had to get permission if it overlapped at all with anything Amazon did and most things overlap with something that Amazon is doing," Tunstall-Pedoe told Business Insider at his home in Cambridge.
