Hidden Systems

Hidden Systems builds AI intelligence products for financial markets. Its main platform, Nebula, takes public market chatter and organises it into structured social intelligence so you can see what topics, companies and narratives are getting attention and how sentiment is shifting.

Nebula is stocks-first and covers public and private equities, AI businesses, major indices, commodities and other market subjects. It offers free public tools alongside paid plans for deeper analysis and workflow features, and the web app lets users examine sentiment, mindshare, emotions, source cohorts, influential accounts and historical change.

• Sentiment and emotion tracking
• Mindshare and narrative detection
• Identification of influential accounts and source cohorts
• API, MCP server and CLI for developer integration

Developers can pull Nebula data into dashboards, alerts, research systems and AI-agent workflows. The platform is positioned as an intelligence and research layer rather than a broker or automated trading service. Hidden Systems also publishes practical guides and research on market sentiment, forecasting and related topics. https://hiddensystems.ai/
