Perplexity, a startup going after Google’s dominant position in web search, has won backing from Jeff Bezos and venture capitalists betting that artificial intelligence will upend the way people find information online.

Started less than two years ago, Perplexity has fewer than 40 employees and is based out of a San Francisco co-working space. The company’s product, which it calls an answer engine, is used by about 10 million people monthly.
