Who should choose which

Before you compare tools, write down what the data has to do once you have it. These checks keep the shortlist honest:

• Team size and seats. Count how many people will use the tool every week. Per-user pricing grows with headcount, while credit or file pricing grows with volume.
• Volume and rhythm. Decide whether you clean one file a quarter or pull records every day. Occasional buyers and steady buyers usually want different plans.
• How the data reaches you. Some teams want a file they can upload to a CRM, others want an API their product calls, and others want everything inside one sales app.
• Channels. Check whether you need email addresses, mobile numbers, company domains or job data, and confirm each one is in the plan you are looking at.
• Contract terms. Look at minimums, annual commitments and whether you can test before paying.
• Reporting and handover. Ask how results come back to you and who on your team picks up the records once they arrive.

With those answers in hand, the fit becomes clearer. Teams that want to start small with US marketing data can stay close to Versium, since it sells pay-as-you-go files with a $125 minimum per file. Product and data teams that want business data inside their own software should look at Coresignal, whose B2B data APIs are built to support long term product and platform needs. Teams that work with AI assistants and want to search job and company data through them can look at TheirStack, which offers an MCP server for that purpose. Sales teams that want prospecting, enrichment and engagement in a single app may prefer Zeliq. Teams whose main worry is email list quality and fraud can look at AtData and its Fraud Consortium. If the only gap in your records is a missing website, Company Url Finder offers a company name to domain service. Teams that already run a customer platform may want to see Clearbit, which is now part of a B2B customer platform.

Versium in detail

Versium describes Versium REACH as a cloud-based Data-as-a-Service platform built to cleanse, enrich and scale US specific marketing data. It says the platform grows with a customer and adapts to changing data needs as the business gets bigger. That makes it a fit for marketing and sales teams whose records are mostly in the US.

The pricing page sets out several ways to buy. Pay-As-You-Go is for low volume needs and carries a $125 minimum per file. Credit Packages are for flexible volume needs and start at $250. Annual Subscriptions are for high volume needs and start at $5,000. Buyers with unusual volumes can ask for a custom pricing proposal shaped around their data needs. Versium also offers free trial access to testing data after you verify your business, so you can judge quality before paying.

Clearbit in detail

Clearbit presents itself as a B2B data provider that is now part of a larger B2B customer platform. For a buyer, that means Clearbit data comes as part of a wider customer platform, so it suits teams that want their company data and their customer records to sit in one system. Pricing is not published on the pages we reviewed. If you are weighing Clearbit against other enrichment tools, our Clay vs Clearbit comparison covers that choice in more depth.

AtData in detail

AtData works on the quality of email lists. In one customer example, it corrects typos using its SafeToSend service, then matches the customer's list and profiles to its database of millions of people who have opted into its ECOA service. It also runs a Fraud Consortium, which identifies and tracks fraudulent email status and history across its platform.

AtData suits teams that hold large consumer or customer lists and want them corrected and checked for fraud before use. Pricing is not published on the pages we reviewed. Teams planning several data sources in sequence may also find our guide to waterfall enrichment for lead gen agencies useful.

TheirStack in detail

TheirStack offers an MCP server so any AI assistant can query its data, with Agent Skills on top that turn a product URL into ready-to-run searches grounded in live counts. The company says hundreds of people sign up for its product every day. It suits technical buyers and teams that already use AI assistants and want to build searches from their own product page.

TheirStack publishes monthly API credit plans:

• 1,500 API credits for $49 per month.
• 5,000 API credits for $100 per month.
• 10,000 API credits for $169 per month.
• 20,000 API credits for $240 per month.
• 50,000 API credits for $400 per month.
• 100,000 API credits for $600 per month.
• 200,000 API credits for $900 per month.
• 500,000 API credits for $1,200 per month.

The stepped plans let a small team begin with a modest monthly amount and move up as usage grows.

Company Url Finder in detail

Company Url Finder offers a company name to domain service. That narrow job is useful when a list has company names and no websites, which often blocks later enrichment steps. It suits operations and research teams that need to fill in domains before they run other tools. Pricing is not published on the pages we reviewed.

Coresignal in detail

Coresignal says its B2B Data APIs offer stable, fresh and high-quality business data to support long term product and platform needs. Its self-service platform is designed for quick access to data and for managing API subscriptions. That makes it a fit for product teams and data teams that want to build business data into their own software.

The pricing page lists a plan at $1,000 per month, at $0.007 per credit. It also offers a way to start free. For more options in the same space, see our roundup of Coresignal alternatives and the People Data Labs vs Coresignal comparison.

Zeliq in detail

Zeliq brings finding, enriching and engaging B2B prospects into one platform. Users can chat with its team directly from the platform for live support. It suits sales teams that would rather work in one app than join a data tool to a separate outreach tool.

Zeliq starts at $1.5k per user per year. It also offers custom enterprise plans with dedicated support, custom integrations and volume pricing. Its pricing page explains that mobile numbers cost more because they are harder to source and verify. You can compare it with similar tools in our list of Zeliq alternatives.

How we compared

This comparison is based on each company's own public pages as of November 2026. We read each tool's public product, pricing and company pages, checked in October and November 2026, and wrote down what each one offers and what it charges. Where a tool lists no price on those pages, we say so plainly. Prices and plans change, so confirm the current figures with each vendor before you buy.
