Overview

Coresignal provides company, professional, and job data drawn from public sources. It says its coverage exceeds 4.5 billion records across more than 15 sources. Three processing levels—Base, Clean, and Multi-source—let teams choose between different degrees of processing; Multi-source combines and enriches records from multiple sources. That range is useful for data pipelines with varied needs, though buyers should decide whether they want source-level records or consolidated data before choosing a workflow.

Data is available through APIs or flat-file datasets in JSON, JSONL, CSV, and Parquet. The company, employee, and jobs APIs support search, collection, bulk collection, and enrichment on applicable endpoints. APIs suit targeted retrieval and ongoing integration; downloadable files are a practical option for teams working in batch-oriented pipelines.

Key features

Intent data and technographic filters add useful targeting dimensions for commercial use cases. Integrations include MCP Server, n8n, Zapier, Clay, Databricks, Google Cloud, Amazon S3, Snowflake, and Azure, giving technical teams several routes into automation and data infrastructure. The product is data infrastructure rather than a finished sales or recruiting application, so it is best for organizations prepared to build workflows around the records.

Coresignal says it collects publicly available, business-related data and does not collect private or sensitive data or access login-secured areas. It says its data processing and privacy policy align with CCPA and GDPR. The company describes security measures including encryption, breach response, web and server security, and restricted access control, and says it follows ISO 27001 requirements without formal certification. That distinction matters to buyers whose procurement process requires formal certification.

Pricing

The free tier costs 0.00 USD per free and provides 2,000 credits, a 5 req/s limit, and email support. The trial credits are valid for 7 days and are issued once per company email domain. It is a short evaluation allowance, not a recurring free allocation, so teams should test representative requests within that window.

Paid monthly plans increase both credits and request capacity:

Plan	Price and allowance	Support
Mini	49.00 USD per month; 2,500 credits/month; 5 req/s	Email
Starter	199.00 USD per month; 12,000 credits/month; 5 req/s	Email
Pro	499.00 USD per month; 35,000 credits/month; 10 req/s	Email
Growth	1000.00 USD per month; 150,000 credits/month; 20 req/s	Account manager
Premium	1500.00 USD per month; 1,000,000 credits/month; 50 req/s	Account manager
Scale	3000.00 USD per month; 4,000,000 credits/month; 100 req/s	Account manager and Slack
Elite	5000.00 USD per month; 10,000,000 credits/month; 100+ req/s	Account manager and Slack

Mini is the entry point for a small, low-volume integration; Starter keeps the same 5 req/s ceiling while adding monthly credits. Pro raises the rate to 10 req/s, while Growth and above add account-manager support and substantially larger allowances. Scale and Elite add Slack support, with Elite suited to the highest stated usage. The lower-cost tiers give up that higher throughput and dedicated support, so they are a poor fit for workloads that must process large volumes quickly.

Platforms

Coresignal is available through API and web. API access and file delivery make it more suitable for teams integrating data into their own systems than for users looking for a standalone database interface alone.

Who it's for

The company identifies investment, sales technology, HR technology, and market research as customer areas. Teams building products or data pipelines around company, employee, or jobs records are the clearest fit. It is less suitable for buyers who need direct-dial data: Coresignal does not provide it.

Pros and cons

Pros: Coverage across 4.5B+ records and 15+ sources gives data builders broad scope across company, professional, and job records.
Pros: API and four flat-file formats accommodate both targeted retrieval and batch data workflows.
Pros: Intent data, technographic filters, and a wide set of integrations support varied enrichment and automation pipelines.
Cons: Credits and request-rate ceilings constrain usage at every paid tier, so teams must match plan capacity to expected demand.
Cons: No direct-dial data makes it a weaker fit when phone contact details are essential.
Cons: ISO 27001 is not formally certified, which may rule it out for procurement requirements that demand certification.

Alternatives

For recruiting workflows, Avery offers ranked matches and a market view for European profiles, with no outreach or contact details on its free plan. Hyranse is another option for candidate discovery, with a free tier that includes limited searches and no API or MCP. Jobin.cloud may suit users seeking contact enrichment and multi-channel outreach in a freemium web, extension, and API product. Pin is worth considering for AI-assisted sourcing and email sequences, while Sprad offers a free ATS Core tier for candidate and pipeline management.

For a candidate-sourcing tool rather than data infrastructure, Juicebox has a one-seat free plan and a Starter plan with 500 monthly contact and export credits. StarHunt offers three searches on its free plan and unlimited searches on Pro. Wiggli may appeal to teams wanting a recruiting workflow with user, credit, and active-project limits. Compare other options in Candidate Sourcing Software, Account Enrichment Software, Data Enrichment Software, Lead Enrichment Software, and B2B Contact Data Providers.

Verdict

Coresignal is a strong fit for technical teams that need broad public business-data coverage, flexible API or file delivery, and processing options across multiple workflows. Its principal advantage is breadth; its principal drawback is that credits and request limits make capacity a recurring plan decision. Look elsewhere if direct-dial data or formal ISO 27001 certification is a requirement.
