Overview

Coresignal says its coverage includes more than 4.5 billion records drawn from over 15 public sources. It offers Base, Clean and Multi-source processing; Multi-source combines and enriches records from multiple sources. That gives data teams a choice between different processing levels, though the product is a data source rather than a finished workflow application.

Teams can retrieve data through company, employee and jobs APIs or use flat-file datasets in JSON, JSONL, CSV or Parquet. The APIs support search, collection, bulk collection and enrichment on applicable endpoints. API access and file delivery make it adaptable to both targeted lookups and larger pipelines, provided a team has the infrastructure to make use of the output.

Key features

Intent data and technographic filters add useful dimensions for commercial targeting. Integrations include MCP Server, n8n, Zapier, Clay, Databricks, Google Cloud, Amazon S3, Snowflake and Azure, giving teams several routes into automation and data platforms. Coresignal identifies investment, sales technology, HR technology and market research as customer areas; it is less suitable for buyers seeking a ready-made candidate sourcing or CRM interface.

Coresignal says it collects publicly available, business-related data, avoids private or sensitive data, and does not scrape behind login-secured areas. It says its privacy practices align with major regulations including CCPA and GDPR. Its security measures include encryption, breach response, web and server security, and restricted access control; it follows ISO 27001 requirements without formal certification. These statements may matter to teams assessing data suppliers, but they do not make it formally ISO-certified.

Pricing

A free tier provides 2,000 credits, a 5 req/s rate and email support for a 7-day trial. Those credits are issued once per company email domain, so the free access is useful for a short evaluation rather than ongoing use. The paid plans retain email support at the lower levels, while higher tiers add account management and, at Scale and Elite, Slack support.

Plan	Price	Credits and rate	Support
Mini	$49/month	2,500 credits/month; 5 req/s	Email
Starter	$199/month	12,000 credits/month; 5 req/s	Email
Pro	$499/month	35,000 credits/month; 10 req/s	Email
Growth	$1,000/month	150,000 credits/month; 20 req/s	Account manager
Premium	$1,500/month	1,000,000 credits/month; 50 req/s	Account manager
Scale	$3,000/month	4,000,000 credits/month; 100 req/s	Account manager and Slack
Elite	$5,000/month	10,000,000 credits/month; 100+ req/s	Account manager and Slack

Mini is the lowest-cost paid entry point, but its 2,500 monthly credits and 5 req/s ceiling leave little room for sustained or bursty workloads. Starter and Pro increase the monthly allowance, with Pro also doubling the request rate to 10 req/s. Growth makes a substantial jump in both credits and rate and adds an account manager; Premium, Scale and Elite are aimed at increasingly high-volume use, with Slack support reserved for the top two tiers. Choose by forecast consumption and request bursts, not just headline price: the included monthly credits and rate caps are the practical constraints. No seat limits are given.

Platforms

Coresignal runs on web and API. Its dataset formats support file-based pipelines, while the listed cloud, storage and workflow integrations offer options for teams already using those environments.

Who it's for

It fits data and product teams that need company, employee or job records for sales technology, HR technology, investment or market research, and can integrate API responses or flat files into their systems. The combination of processing levels, formats and integrations is a strength for teams with varied pipelines. It is a weaker fit for individuals or small teams that need an end-user recruiting product, direct-dial data, or generous ongoing usage at a low monthly cost: direct-dial data is not offered, and the free tier expires after seven days.

Pros and cons

Pros: Large stated coverage across more than 15 public sources, with company, employee and jobs data in one provider.
Pros: APIs and four dataset formats, plus three processing levels, let teams choose how to retrieve and work with records.
Pros: Intent data, technographic filters and integrations support a range of business-data workflows.
Cons: The free 2,000-credit trial lasts only seven days and is limited to one issuance per company email domain.
Cons: Monthly credit quotas and request-rate caps constrain throughput, particularly on the lower-priced plans.
Cons: No direct-dial data, and ISO 27001 alignment is not formal certification.

Alternatives

For a recruiting workflow rather than a broad business-data pipeline, Jobin.cloud has a free plan with 30 enrichment credits, up to 50K contacts, unlimited jobs and projects, and limited multi-channel outreach automation. Hyranse may suit a reader who wants a recruiting-oriented web and extension product with a small free allowance: its free plan includes five monthly contact credits and two AI searches, but no API or MCP. Pin is another freemium option, with five contact lookup credits per week and email-only sequences on its free plan.

For a broader shortlist of tools, see Candidate Sourcing Software, Data Enrichment Software, Lead Enrichment Software, Account Enrichment Software and B2B Contact Data Providers.

Verdict

Coresignal is a strong choice for teams that need large-scale company, professional and job data in API or file pipelines, especially when they can use its processing options and integrations. Its main trade-off is predictable: monthly cost rises with the credit volume and request rate needed, while the trial is brief. Choose it when those limits match a defined data workload; look elsewhere if you need direct-dial numbers or a ready-to-use recruiting application.
