About Crisp

Crisp provides 24/7/365 early-warning risk intelligence as a service for leading brands, global enterprises and social media platforms, providing customers with a real-time risk defence, and with intelligence and compliance solutions guaranteed to ensure our customers are always the first to know and act. These risks can take many forms, including activist attacks, hate speech, threats, fake news, false rumours, illegal content, compliance failures and many more. Fuelled by the increased popularity of closed social media groups and messaging apps, this harmful content can now spread virally, at scale before it reaches mainstream media channels.

The relentless focus on helping to create a digital world that is safe for everyone has been Crisp’s mission from day one. Today that passion extends to working with leading brands, global enterprises and social media platforms.
