L1ght is an anti-toxicity startup that leverages intelligence (big data, deep learning) and human knowledge, in order to analyze and predict online toxicity. It analyzes texts, images, video, voice and sound to protect children from harmful incidents. The startup made headlines for removing over 130K pedophiles from public groups on WhatsApp, and for getting Google and Facebook to purge apps that were monetizing links to questionable WhatsApp groups. They later got Bing to remove underage porn from its search results. The AI component is leagues ahead of dictionary blacklists most of us are familiar with from social networks.
