Overview

Coresignal says its coverage spans more than 4.5 billion records across 15-plus public sources. It offers Base, Clean and Multi-source processing; the last combines and enriches data from multiple sources. That gives builders a choice between source-level data and consolidated records, rather than forcing one processing approach across every workflow.

The platform provides company, employee and jobs APIs, with search, collect, bulk collect and enrichment capabilities on applicable endpoints. Flat-file datasets are available in JSON, JSONL, CSV and Parquet, so teams can choose API calls for targeted retrieval or files for larger data workflows.

Key features

The breadth of company, employee and jobs data can serve several business workflows through one provider. Technographic filters and intent data add useful dimensions for commercial targeting, while integrations include MCP Server, n8n, Zapier, Clay, Databricks, Google Cloud, Amazon S3, Snowflake and Azure. This is a practical fit for teams that want to connect data collection to existing automation or storage tools.

Coresignal says it collects publicly available, strictly business-related data, does not collect private or sensitive data, and does not scrape behind login-secured areas. It says its processing and privacy policy align with major regulations including GDPR and CCPA. It also says it follows ISO 27001 requirements without formal certification, and describes encryption, breach response, web and server security, and restricted access control. Teams with formal certification requirements should account for that distinction.

Pricing

The free tier costs 0.00 USD per free and includes 2,000 credits, a 5 req/s limit, email support and a 7-day trial. Trial credits are valid for seven days and issued once per company email domain, so this is a short evaluation window rather than an ongoing free allowance.

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

Mini is the low-cost paid entry point, but 2,500 monthly credits and 5 req/s suit restrained use more than sustained enrichment. Starter and Pro increase the credit pool, with Pro also raising the request ceiling. Growth is a substantial step up in both capacity and support; Premium, Scale and Elite target progressively heavier throughput, with Slack support reserved for the top two plans. Choose by expected credit consumption and request rate, not monthly price alone. The published plan details give no seat quotas.

Platforms

Coresignal is available on API and web. Dataset delivery in four formats supports batch-oriented workflows, while the integration roster covers automation platforms, cloud services and data warehouses.

Who it's for

Sales and investment teams can use company, professional, intent and technographic data; HR technology teams can draw on employee and jobs data; market researchers can work with the broader public-web dataset. It is best suited to teams able to estimate usage and route records into an established data workflow. It is a weaker fit for buyers who require direct-dial data: Coresignal does not provide it.

Pros and cons

Pros: Company, employee and jobs APIs plus flat files let teams match delivery to their pipeline and workload.
Pros: Base, Clean and Multi-source processing offer different levels of consolidation, including cross-source enrichment.
Pros: The 49.00 USD per month Mini plan provides a low-cost paid starting point, and higher tiers scale to 10,000,000 monthly credits.
Cons: The free tier lasts only seven days, and its one-time-per-company-domain credit issue limits repeat evaluation.
Cons: Direct-dial data is absent, which rules it out for workflows that depend on those records.
Cons: ISO 27001 requirements are followed without formal certification, which may not satisfy teams that require certified status.

Alternatives

For a broader data enrichment software shortlist, compare tools by the data types and workflow each supports. The candidate sourcing software, lead enrichment software, account enrichment software and B2B contact data providers directories can help narrow the choice by use case.

BetterContact is worth comparing when the stated per-credit exchange of 1 phone for 10 credits or 1 email for 1 credit better matches a contact-finding workflow. People Data Labs is an API-only freemium alternative, with listed IP Enrichment API tiers measured in credit ranges. TargetWise is another freemium API and web option, with a free plan for work emails and business-phone results plus dashboard, API and MCP access. OpenGTM suits teams seeking open-source self-hosting; it is free, though third-party provider costs may apply.

Precisely EnterWorks is another paid API and web platform. 6sense is a paid API option with predictive AI, sales copilot and company and contact data acquisition. Databar may suit teams looking for a paid enrichment platform with workspace editors, custom HTTP APIs and batch enrichment. FullEnrich offers a paid API and web option with a free trial.

Verdict

Coresignal is a strong fit for teams that need broad company, employee and jobs data with a choice of API or file delivery and multiple processing levels. Its main advantage is the combination of source coverage and workflow flexibility; its main reasons to look elsewhere are the short, one-time trial, credit-based monthly limits and lack of direct-dial data. Estimate demand carefully before choosing a tier, especially if request throughput or support needs will grow.
