Enrich B2B data in real time

Data enrichment software enhances existing records by appending additional, relevant information from external sources. This may include firmographic, technographic, or demographic data to support more accurate targeting, segmentation, or analysis.

‍

For B2B companies, enrichment helps transform basic lead or customer data into actionable profiles. It ensures that your databases stay current, complete, and useful for various operational workflows. Most enrichment tools integrate with CRMs, marketing platforms, or analytics stacks to deliver real-time value via data APIs.

Several B2B data enrichment tools stand out due to their scale, accuracy, and integration options. Leading public web data provider Coresignal provides access to processed public web data at scale, which is ideal for building custom data pipelines or powering enrichment engines with fresh, reliable information.

‍

Some other providers are Clearbit that offers enrichment for marketing and sales workflows, ideal for startups and mid-size teams. ZoomInfo is widely used for enterprise-grade lead intelligence.

‍

The best tool depends on your business goals, technical setup, and desired level of customization.

If you're looking for real-time enrichment with API access, here are some of the leading providers:

‍

1. Coresignal – Offers Company, Employee, and Job APIs for on-demand access to fresh public web data. Ideal for scaling enrichment pipelines, especially in HR tech, sales, and investment platforms.
2. Clearbit – Provides real-time person and company enrichment through its APIs, commonly used for lead scoring and personalization.
3. Lusha – Offers real-time B2B contact and company data via API, with a strong focus on sales prospecting and compliance.

‍

When evaluating providers, check update frequency, data sources, and API flexibility to ensure they match your requirements.

To validate leads effectively, start by identifying the key attributes that define a qualified contact or company. This may include firmographics, job titles, or industry markers.

‍

You can source this data through enrichment providers, third-party databases, or APIs that deliver updated records. Public web data sources are especially useful for B2B validation, as they provide accurate signals about a company’s growth, hiring trends, or tech stack. It's also helpful to use job posting or employee data to verify role relevance and company intent.

‍

Combining data from multiple data sources and cleaning the dataset reduces the risk of chasing low-quality leads.

Start by auditing your current dataset to identify missing or outdated fields. Then, choose an enrichment source – either a database provider such as Coresignal's API service, or bulk enrichment tool that offers the attributes you need.

‍

Match your internal records with external identifiers like domain names, emails, or company names to append new data points. Depending on your setup, enrichment can be done in real time via API or in batches via CSV or data pipelines.

‍

Finally, validate and clean the enriched data to ensure consistency and accuracy before integrating it back into your systems.
