ColdIQ

ColdIQ offers a data API and Slack integration that lets organizations search for companies and people, enrich domains and contacts, verify emails and phone numbers, and pull buying signals within one chat or coding environment. The system supports Claude Code, Cursor and Slack, and exposes a REST API and MCP to connect to developer workflows. It operates with multiple data providers and evaluates results to route calls to the best provider.

The tool is designed for GTM teams, including sales, marketing, and recruiting roles, enabling cross-functional prospecting and enrichment within familiar workspaces and tooling. It presents a single interface to access data from many sources, with a focus on speed and accuracy in delivering contact details and firmographic signals.

ColdIQ emphasizes an automated routing approach, where each request is scored across providers for fit and cost, and the winning provider is called. It supports waterfall fallbacks so that if one source is unavailable, another is tried. The system also includes an agent that can be used in Slack or in the user’s terminal or browser.

The pricing model is credits-based with a free tier and multiple paid plans. Plans include access to 40+ data providers and 700+ endpoints, with additional features like CSV enrichment, API access, and Slack integration.
