Overview

Coresignal says its coverage spans more than 4.5 billion records from over 15 sources. Teams can select Base, Clean, or Multi-source processing; the last combines and enriches records from multiple public sources. That range is valuable when workflows need different levels of consolidation, though buyers should account for how their chosen processing level fits their data pipeline.

Company, employee, and jobs APIs support search, collection, bulk collection, and enrichment on applicable endpoints. Teams can instead use flat-file datasets in JSON, JSONL, CSV, or Parquet. This makes Coresignal more suitable for builders integrating data into their own systems than for people looking for a finished sales or recruiting application.

Key features

Intent data and technographic filters add targeting dimensions to the company and professional data. The integration roster includes MCP Server, n8n, Zapier, Clay, Databricks, Google Cloud, Amazon S3, Snowflake, and Azure, which gives teams several ways to connect collection to automation, storage, and analytics workflows.

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 policy and data processing align with regulations including CCPA and GDPR. Its security description includes encryption, breach response, web and server security, and restricted access control; it follows ISO 27001 requirements but does not hold formal certification. That distinction matters to organizations whose vendor policies require certification rather than alignment with a standard.

Pricing

The Free tier costs 0.00 USD per free and provides 2,000 credits, 5 req/s, and email support for a 7-day trial. Those credits are issued once per company email domain, so this is a short evaluation window, not a recurring free allowance. Mini starts paid access at 49.00 USD per month, billed $49/month, with 2,500 credits/month, 5 req/s, and email support. It suits light API use, but the small quota leaves little room for repeated or bulk requests.

Starter costs 199.00 USD per month, billed $199/month, for 12,000 credits/month at 5 req/s with email support. Pro costs 499.00 USD per month, billed $499/month, and raises that to 35,000 credits/month and 10 req/s, still with email support. These tiers fit teams with more regular retrieval needs, while the higher rate limit on Pro is relevant when requests need to run faster as well as more often.

Growth is 1000.00 USD per month, billed $1,000/month, for 150,000 credits/month at 20 req/s and account-manager support. Premium costs 1500.00 USD per month, billed $1,500/month, and includes 1,000,000 credits/month at 50 req/s with an account manager. The jump in quota makes Premium a more plausible choice for substantial production pipelines; Growth is a lower-cost step for teams whose usage stays within its smaller allowance.

Scale costs 3000.00 USD per month, billed $3,000/month, with 4,000,000 credits/month, 100 req/s, an account manager, and Slack support. Elite costs 5000.00 USD per month, billed $5,000/month, for 10,000,000 credits/month, 100+ req/s, and the same support channels. These are enterprise-scale quotas and support, not economical starting points for small projects. Across the paid tiers, the monthly credit pool and request rate are the key constraints; plan carefully around both rather than price alone.

Platforms

Coresignal is available on web and through APIs. API access and dataset delivery give technical teams options for targeted requests or file-based pipelines; no direct-dial data is offered, so buyers specifically needing that data should look elsewhere.

Who it's for

Coresignal identifies investment, sales technology, HR technology, and market research as customer areas. It is a strong fit for teams building data into internal tools, enrichment workflows, or analytics stacks, especially when multi-source records or multiple output formats are useful. It is less appropriate for a user who wants a ready-made contact app or direct-dial information.

Pros and cons

Pros: Coverage across companies, professionals, and jobs with 4.5B+ records from 15+ sources can serve multiple business-data workflows.
Pros: API and flat-file delivery in four formats, plus three processing levels, let technical teams choose how to retrieve and consolidate data.
Pros: Intent data, technographic filters, and a broad set of integrations support targeted workflows and connections to common automation and data platforms.
Cons: The free tier lasts only 7 days, and its 2,000 credits are issued once per company email domain, limiting evaluation to a brief trial.
Cons: The entry paid tier provides just 2,500 credits/month at 5 req/s; teams with sustained or high-volume needs must move to substantially more expensive plans.
Cons: There is no direct-dial data, and ISO 27001 requirements are followed without formal certification, which may rule it out for some buyers.

Alternatives

Data Enrichment Software, Account Enrichment Software, Lead Enrichment Software, Candidate Sourcing Software, and B2B Contact Data Providers are useful categories for comparing products by workflow.

B2BEnrich is a reasonable alternative for testing person and company enrichment on a free plan with 50 monthly credits, rather than Coresignal's 7-day, 2,000-credit trial. Clay offers 500 actions/month and 100 data credits/month on its free plan, with unlimited seats and tables, making it worth considering for a small team focused on lead-enrichment workflows. TargetWise provides a free allowance of 20 work emails and 5 business-phone results, plus dashboard, API, and MCP access, for buyers wanting a limited free contact-data option.

OpenGTM is an open-source self-hosted option for teams willing to run software on their own infrastructure, with third-party provider costs potentially applying. People Data Labs is another API-based alternative. BetterContact starts at 15.00 USD per month for 200 credits/month, with phone and email results consuming credits at different rates. Precisely EnterWorks is a demo-led option that requires an active entitlement for downloads.

Verdict

Coresignal is a compelling choice for technical sales, HR, investment, and research teams that need broad public business data in APIs or bulk files and can forecast their monthly usage. Its multiple data types, processing levels, and integration options are the main reasons to choose it. Look elsewhere if direct-dial data is essential, a formal ISO 27001 certification is required, or a small project cannot justify the paid tiers after the brief trial.
