Twitter, Craigslist Co-Founders Back Fact-Checking Startup Factmata

Company aims to use artificial intelligence to weed out fake news

Twitter Inc. co-founder Biz Stone and Craigslist Inc. co-founder Craig Newmark are investing in London-based fact-checking startup Factmata, the company said Thursday.

It declined to disclose either the amount of the investment or the valuation of the deal.

“It's critical for societal progress to proactively address misinformation,” Stone said in a statement provided by Factmata. He said the company is “approaching the issue with exactly the right combination of big thinking, focus, and cutting-edge science.”
