Profile
Signal AI monitors and analyzes public content from news and social media across 120+ languages to help large organizations detect risks, manage reputation, and inform strategy.
Signal AI, founded in 2013 and headquartered in the United Kingdom, provides a platform that ingests and analyzes external data from traditional and social media across 226 markets and 120+ languages. The company's core offering, branded AIQ, blends generative and discriminative AI to deliver insights for enterprise risk management, reputation monitoring, PR and communications strategy, and regulatory tracking. In 2026, Signal AI closed a $165 million investment round led by Battery Ventures, marking a significant capital infusion for a company that had previously raised $50 million in a 2021 Series D.
The company claims Fortune 500 companies as clients, though specific named customers are not disclosed in available materials. Signal AI positions itself as a tool for moving beyond vanity metrics like impressions toward outcome-based reporting that demonstrates ROI to CFOs. The company's 2026 report on trends in PR and marketing highlights the shift from generative to agentic AI, the rise of Generative Engine Optimization (GEO) as traditional search volume is projected to drop 25%, and the need to combat synthetic reputational attacks and deepfakes.
Signal AI's platform is designed to surface threats, benchmark against competitors, and provide ongoing surveillance across an organization's own operations and its broader industry. The recent Battery Ventures investment suggests a growth-stage push, though the company's revenue figures and valuation remain undisclosed in public filings.
