Mission-driven, customer-obsessed

Pendulum is deeply inspired by mission, motivated by solving hard problems, and obsessed with empowering our customers. These core tenets arose from our initial vision of disrupting the threats that harmful narratives pose to society, and remain central to our mission today.

Our initial focus on threats led us to a broader insight - we live in a digital, interconnected world where audio and video rule - and where text is yesterday's news. For anyone who needs to understand the pulse of conversations online, Pendulum delivers unique insights on critical topics, communities, narratives, and claims - when they appear, how they spread, and what they mean - empowering them to respond early and effectively.
