I'm the CEO of a fast-growing AI startup. Alex asked to meet with us about a year ago (when we were about 1/10th the size), and after asking us to prepare lots of materials, they indicated they wanted to buy us or invest in us. People warned us not to talk to them because they have a reputation for gathering technical detail, and then trying to copy it rather than striking a deal. Our software could have radically accelerated and improved the Alexa experience basically overnight.
At one point in the meeting, the head of Alexa's M&A/investment team said "tell us how much you think you're worth." I threw out a number, and he laughed and left the room.
Today we're valued at more than that number and Alexa's core experience hasn't changed in the past year. They haven't been able to copy us. The Alexa leadership team has some hubris IMO.
