What is Coresignal?
Coresignal is a B2B data provider founded in 2016 and headquartered in New York. It sells structured company, employee, job-posting, and social-post data collected from multiple public web sources. Datasets include company records (70M-106M+, 500+ fields), employee profiles (700M-895M+, 300+ fields), and job postings (413M-468M+ listings, 85+ fields). Access comes through REST APIs (Company, Employee, Jobs, and a newer natural-language Agentic Search API), bulk flat-file exports, an MCP Server for AI-agent integration, and a Snowflake Marketplace listing with Databricks, AWS, GCP, and Azure integrations. The company reports serving 400 to 1,000+ client organizations in sales intelligence, recruiting/HR tech, investment research, and AI/LLM training.
Our verdict
Access methods here range from APIs and bulk files to an MCP Server and a Snowflake listing, which makes Coresignal a reasonable fit for teams that need large volumes of structured company and people data rather than a single narrow API. Coverage and client-count figures vary across the vendor's own materials, and the company discloses no funding or independent coverage, so it's worth verifying data quality and freshness directly rather than taking the stated scale at face value.

Data providers skip the scraping step: you buy a maintained dataset or a feed of company, contact, or product data on a subscription. This fits teams that need the data rather than the pipeline, and want to avoid the legal and maintenance burden of collecting it themselves.
