Signalbase
Overview
Signalbase is a real-time business signal detection platform that monitors, verifies, and delivers pre-validated funding, acquisition, hiring, and leadership change signals to GTM teams and AI agent workflows through a clean, structured API.
Core Features:
Six core signal types covering funding rounds, acquisitions, hiring activity, job changes, investor profiles, and company data, each verified before delivery with structured metadata, source links, and confidence scoring to ensure production-grade reliability.
Real-time signal detection that continuously monitors thousands of sources for business changes, delivering alerts within minutes so sales teams can act on funding rounds, leadership moves, and M&A activity before competitors.
API-first architecture with webhooks, MCP server integration, and structured JSON output designed for production use, making it straightforward to pipe verified signals directly into CRMs, sales engagement platforms, or custom GTM workflows.
Global coverage with normalised data schemas across all signal types, eliminating the need for teams to build and maintain their own scraping, verification, and normalisation pipelines from scratch.
Native MCP server for AI agent integration, allowing tools like Claude Code and Cursor to query funding, hiring, investor, and company data directly, enabling signal-powered autonomous prospecting workflows.
Best For:
GTM teams and developers building signal-based outbound workflows who need a reliable, API-accessible data layer rather than a full-featured UI platform. Particularly valuable for teams using Clay, AI SDR agents, or custom pipelines that need verified real-time signals as an input. Also strong for VC and market intelligence use cases. HubSpot integration and CSV exports included.
