Overview

Coresignal says its data spans more than 4.5 billion records across over 15 public sources. Buyers can choose Base, Clean, or Multi-source processing; Multi-source combines and enriches records from multiple sources. That flexibility serves teams that need different levels of processing, though it also means buyers should decide which form fits their data pipeline rather than treating every record as equally processed.

Company, employee, and jobs APIs support search, collection, bulk collection, and enrichment where applicable. Teams can also use flat-file datasets in JSON, JSONL, CSV, or Parquet. API access suits targeted or ongoing retrieval, while downloadable files offer a route for teams that prefer dataset-based workflows.

Key features

Intent data and technographic filters add useful targeting dimensions to the core business records. Integrations include MCP Server, n8n, Zapier, Clay, Databricks, Google Cloud, Amazon S3, Snowflake, and Azure, making Coresignal more compelling for teams connecting data to existing automation, cloud storage, or analytics tools than for people seeking a finished sales or recruiting application.

Coresignal says it collects publicly available, business-related data, avoids private or sensitive information, and does not scrape behind login-secured areas. It says its privacy approach aligns with GDPR and CCPA. The company also says it follows ISO 27001 requirements without formal certification, and describes encryption, breach response, web and server security, and restricted access controls. These statements may matter to buyers assessing vendors, but the lack of formal ISO certification is a distinction for procurement teams that require certified controls.

Pricing

The Free tier costs 0.00 USD per free and provides 2,000 credits, 5 req/s, email support, and a 7-day trial. Trial credits expire after 7 days and are issued once per company email domain, so this is a limited evaluation rather than an ongoing free allowance.

Mini costs 49.00 USD per month, billed $49/month, for 2,500 credits/month, 5 req/s, and email support. It is the lowest-cost paid entry, but its small monthly allocation makes it better suited to modest retrieval needs than sustained, high-volume use. Starter costs 199.00 USD per month, billed $199/month, and raises the allowance to 12,000 credits/month while keeping the 5 req/s ceiling and email support. Pro costs 499.00 USD per month, billed $499/month, for 35,000 credits/month and 10 req/s, still with email support. These tiers increase capacity in steps, but retain relatively low request ceilings compared with the upper plans.

Growth costs 1000.00 USD per month, billed $1,000/month, and includes 150,000 credits/month, 20 req/s, and an account manager. Premium costs 1500.00 USD per month, billed $1,500/month, for 1,000,000 credits/month, 50 req/s, and an account manager. The jump in credits makes Premium a substantial capacity step for data-intensive use; Growth is more restrained but already moves beyond email support.

Scale costs 3000.00 USD per month, billed $3,000/month, and includes 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, and provides 10,000,000 credits/month, 100+ req/s, an account manager, and Slack support. These plans are aimed at sustained large-scale workloads where higher throughput and direct support justify the outlay. No seat limits are stated for these plans.

Platforms

Coresignal is available on API and web. Its dataset downloads and integrations broaden the ways teams can put the data to work, but its central value is access to data rather than a standalone workflow interface.

Who it's for

Coresignal is a strong fit for technical sales, HR, investment, and research teams that need broad business records and can integrate API responses or flat files into their own systems. It is less suitable for buyers who need direct-dial data, a ready-made prospecting workflow, or predictable costs without closely managing credit and request consumption.

Pros and cons

Pros: Broad coverage across companies, professionals, and jobs gives teams several business-data categories through one provider.
Pros: API and multiple flat-file formats accommodate both application integrations and batch-oriented data pipelines.
Pros: Base, Clean, and Multi-source processing options let teams choose between different processing approaches.
Cons: The 2,000-credit trial lasts only 7 days and is limited to once per company email domain, restricting evaluation time and repeat trials.
Cons: Lower-priced tiers have modest credit quotas and request-rate ceilings, which may constrain growing or bursty workloads.
Cons: Coresignal does not provide direct-dial data, ruling it out for workflows that depend on that contact channel.

Alternatives

For candidate sourcing, compare Candidate Sourcing Software if the priority is sourcing candidates rather than buying underlying business data. For lead workflows, Lead Enrichment Software and Account Enrichment Software are category directories to consider when enriching leads or accounts is the central need. Data Enrichment Software is a broader category to explore when enriching records beyond Coresignal's company, employee, and jobs focus, while B2B Contact Data Providers is a relevant directory for comparing providers, particularly if direct-dial data matters.

Jobin.cloud is worth considering for a free forever plan with 30 enrich credits, up to 50K contacts, unlimited jobs and projects, and limited multi-channel outreach automation. Hyranse offers a free plan with five monthly contact credits and two AI searches, but no API or MCP on that tier, making it a less direct fit for API-centered data workflows. Pin has a free tier with five contact lookup credits per week and email-only sequences, which may suit a very small contact lookup need. Sprad offers a free ATS Core plan with career-site, pipeline, candidate-management, team, and analytics features, so it is more relevant when the need is applicant tracking. Avery provides free access to search 125M+ vetted European profiles and ranked matches, but excludes outreach and contact details on its free plan. Juicebox has a free plan for one seat and a Starter plan at 119.00 USD per month for one seat, 500 contact credits, and 500 export credits, giving candidate-sourcing teams another option. Loxo is an alternative to consider for recruiting teams seeking a platform with jobs, candidates, and companies. Blosto is another candidate-sourcing alternative, with a Starter plan at 125.00 USD per month for one seat and 250 shortlist credits per month.

Verdict

Choose Coresignal if your team needs large-scale company, professional, or job data delivered through APIs or datasets, and can manage usage within monthly credit and request limits. Its breadth, processing options, and integration choices make it a capable data source for technical business workflows. Look elsewhere if direct-dial data or a ready-to-use recruiting or prospecting product is essential, or if the trial and lower-tier quotas are too restrictive for your evaluation and workload.
