ActiveFence, a service for trust and safety intelligence and management that works to protect online businesses and users from malicious content and backed by CRV and Norwest, has bought Rewire, a London-based startup that builds AI for online safety.

Rewire has developed a catalog of AI models for detecting different types of text-based content, including insults, hate speech, profanity, violence, explicit language and suicide and self-harm content. The company will work to support and drive ActiveFence’s existing AI text models. Combining ActiveFence’s trust and safety platform, content detection AI models and API with Rewire’s text models aims to arm customers against malicious behavior, helping them to find and take action against dangers in real time.

 “Joining forces with Rewire will allow us to build even more accurate and trustworthy models more efficiently, bringing together Rewire’s high-quality datasets with ActiveFence’s assets and infrastructure to create a significant step forward in AI for online safety at scale,” states Noam Schwartz, ActiveFence CEO and co-founder.
