What is Coresignal and How Does it Work?

Coresignal positions itself as a B2B data provider that collects information from public web sources to build datasets about companies, employees, and job postings. They target sales teams, recruiters, and data analysts who need access to professional information at scale.

The company operates by scraping publicly available information and organizing it into structured datasets. Their approach focuses on bulk data delivery and API access, allowing customers to integrate professional data into their existing workflows and applications.

According to industry reviews, Coresignal serves mid-market and enterprise customers who need large volumes of B2B data. Their business model revolves around subscription-based access to their datasets, with pricing that scales based on usage and data volume requirements.

The service appeals to organizations that can handle data preprocessing and normalization internally. Data provider profiles indicate they focus on companies with technical teams capable of working with raw datasets rather than plug-and-play solutions.

Data Types, Sources, and How It Is Structured

Coresignal organizes their data into three main categories: company profiles, employee records, and job postings. Their company dataset includes basic firmographic information like industry, size, location, and founding details.

The employee dataset contains professional information scraped from multiple public sources. This includes job titles, work history, skills, and employment timelines. However, the data structure requires major cleanup before it becomes actionable for most use cases.

Job posting data covers active and historical job listings from company websites and job boards. This dataset includes job descriptions, requirements, posting dates, and location information.

Coresignal's data structure requires extensive preprocessing and normalization before it becomes useful for most applications, adding major development overhead.

Their API endpoints provide access to these datasets through REST calls, but the response format often contains inconsistencies that require additional parsing. The B2B data market has evolved toward more standardized, ready-to-use formats that reduce integration complexity.

Coresignal Features

Coresignal offers several core features designed for bulk data access and integration. Their Company API provides access to firmographic data including company size, industry classification, and basic contact information.

The Employee API delivers professional profiles with work history, job titles, and skills data. This feature targets recruiting and sales prospecting use cases where teams need to identify decision makers and build contact lists.

Their Job Postings API tracks hiring activity across companies, providing insights into growth patterns and organizational changes. This data helps identify companies in expansion phases or specific hiring needs.

Bulk dataset access allows customers to download entire datasets for internal processing. This approach works well for organizations with data engineering resources who prefer to work with complete datasets rather than API calls.

Data enrichment tools in the market have moved toward real-time enrichment, but Coresignal still has elements of a batch-processing approach. Their webhook functionality provides notifications for data updates, though these updates happen on monthly cycles rather than real-time.

The service includes basic filtering and search features through their API endpoints. However, advanced search functionality requires additional development work compared to more modern company enrichment and people enrichment solutions.

Coresignal Key Limitations and Gaps

The biggest limitation with Coresignal is data freshness. Industry feedback consistently points to data that's 3-4 months old or older, which creates problems for time-sensitive applications like AI SDRs or recruiting outreach.

Their refresh rates vary dramatically depending on scraping resources, with most data delivered on monthly cycles. This inconsistency makes it difficult to rely on current information for decision-making processes that require up-to-date insights.

Pricing transparency remains a major pain point. Users report frustration with the lack of clear pricing information and the need for extensive sales conversations before understanding actual costs.

The preprocessing requirements create substantial overhead. Unlike modern data providers that deliver clean, normalized data, Coresignal's raw datasets require extensive cleanup work before they become useful for most applications.

Real-time data matters for AI-driven applications, but Coresignal's batch approach doesn't align with the immediate data needs of modern sales and recruiting tools.

The self-service experience needs improvement. Alternative providers offer more direct onboarding and testing processes, while Coresignal requires major upfront investment before teams can properly assess the data quality.
