Talking point: OpenAI’s ChatGPT introduced many consumers to a bot that can hold a conversation. Sector players project AI “agents” as the next big thing—tools that can not only talk to users about things, but actually go out and do things like buying items or making appointments on their behalf. Businesses can use Sierra’s technology to generate bots to serve their customers. The stealth startup has attracted attention in the tech sector since Taylor teased it a year ago, right after his Salesforce exit. Co-founder Clay Bavor was a longtime Alphabet executive, most recently running its Google Labs division. Sierra has reportedly already raised US$110 million from the likes of prominent venture capital firms Sequoia Capital and Benchmark.
