Coresignal

Coresignal has carved out a strong position in the B2B data market by focusing on fresh, structured public web data. With over 4.5 billion data records and 700+ customers globally, the company provides datasets and APIs covering companies, employees, job postings, and social posts. Its core value proposition is data freshness -- more than 695 million records are updated monthly, making it one of the more current data sources available for sales, investment, and HR use cases.

The platform offers three primary datasets: company data (75.7M+ records with 500+ fields), employee data (890.9M+ records with 300+ fields), and job posting data (460.5M+ deduplicated listings). Each dataset includes historical data going back to 2016, enabling trend analysis and longitudinal studies. Coresignal also provides APIs for each dataset, plus a newer Agentic Search API that allows natural language queries for AI-driven workflows. The company has invested heavily in data privacy compliance and claims to meet the highest standards.

Pricing is structured in two tiers. Dataset purchases start at $1,000, with costs varying by contract length and data sources. Database API subscriptions begin at $49 per month, with a free plan available and annual discounts. This makes Coresignal accessible to smaller teams through the API tier, while the dataset pricing is more suited to mid-market and enterprise buyers who need bulk data for internal systems or AI model training.

Coresignal is best for organizations that need reliable, frequently updated public web data at scale. Sales teams can use it for lead enrichment and prospecting, investment firms for company and market analysis, and HR tech companies for talent sourcing and analytics. The data is also well-suited for training AI and machine learning models, as it's structured and includes rich metadata. However, smaller businesses or occasional users may find the dataset pricing steep, and the raw data often requires preprocessing before it can be used effectively in downstream applications.

Overall, Coresignal is a solid choice for data-driven teams that prioritize freshness and breadth over turnkey simplicity. Its API performance (176 ms average response time) and multi-source approach give it an edge over providers that rely on a single data source. If your workflow can handle some data processing overhead and you need up-to-date B2B intelligence, Coresignal delivers reliable, scalable data that integrates well with modern sales and analytics stacks.
