CompanyData.com, BoldData vs Kaspr: B2B Data Compared

Three vendors. Three very different products. One confusing search. If you typed CompanyData.com, BoldData vs Kaspr into Google, you were likely comparing tools that don't do the same job. This guide fixes that. It shows what each tool is built for, what it costs, and where it falls short.

TL;DR — Which one should you pick?#

• CompanyData.com is a firmographic database. It sells bulk company records, industry codes, and account lists. Use it for market sizing and TAM work. It is weak on individual contact details.
• BoldData is a custom list broker from the Netherlands. You give them your criteria. They deliver a one-time company or contact file. It is great for one-off campaigns, not for ongoing prospecting.
• Kaspr is a real-time LinkedIn contact finder. You install a browser extension, open a profile, and it reveals phone numbers and emails. It is built for SDR outreach, not database exports.
• None of them is mainly an email-finding engine. If you need accurate, verified work emails, a dedicated email finder with a verification layer beats all three on cost per valid contact.
• Your real question is not "which is best." It is "which data model fits my workflow." This post answers that.

CompanyData.com, BoldData vs Kaspr: what does each tool do?#

This comparison feels slippery for one reason. These are three different product types wearing similar marketing language.

CompanyData.com sells access to a large firmographic dataset. Think company names, sizes, revenue bands, SIC/NAICS codes, locations, and sometimes technographics. You use it to build target account lists or size a market. It is a phone book for companies, not for people. It answers "which 4,000 mid-market logistics firms exist in Texas." It does not answer "who is the VP of Ops, and what is her cell number."

BoldData works like a data agency. You send a brief — say, "manufacturing companies in Germany, 50–200 employees, with a purchasing contact." They compile and sell you a custom list. It is a transaction, not a subscription. The strength is coverage where self-serve tools are thin: Europe, APAC, and long-tail industries. The trade-off is simple. The data ages the moment it lands, and you re-buy for every campaign.

Kaspr is the outlier. It is a live enrichment tool. It pulls contact details — direct dials, mobiles, and emails — while you browse LinkedIn or work a list. It is an SDR's daily driver. It is priced per credit and tuned for speed over bulk. Its coverage is strongest in Europe for mobile numbers, which is its standout feature.

How do CompanyData.com, BoldData, and Kaspr compare on the essentials?#

Here is the honest side-by-side. Prices change, so treat these as directional. Confirm on each vendor's site before you buy.

The pattern is clear once you lay it out. CompanyData.com and BoldData are account-level tools. Kaspr is a person-level tool. If you compare them head to head, you are likely trying to solve two problems with one purchase: build a list, then reach people. No single vendor here does both well.

Which delivers the most accurate contact data?#

Accuracy is where the marketing gloss wears off fastest. So be specific about what you measure.

For company records, CompanyData.com and BoldData are usually reliable. Firmographics change slowly. A company's industry code or headcount band stays valid for months. The risk is stale data on recent funding, acquisitions, or office closures.

For individual contact details, the story is different. These emails and phone numbers decide whether your outreach lands:

1. Bulk lists decay fast. Each year, about 22–30% of B2B contact data goes stale as people change jobs. A BoldData file bought in January is clearly worse by June.
2. "Unverified" hides a lot. Lists shipped without an SMTP check often include catch-all domains, role accounts, and dead mailboxes. Those hurt your sender reputation.
3. Kaspr's real-time model helps. It pulls the contact at the moment you need it. But coverage is uneven outside Europe, and email quality still varies by profile.

A verification workflow closes this gap. Whatever list you buy, run it through an email verifier before you send. That strips out the invalid addresses that would otherwise bounce. And if you find emails fresh instead of buying a static file, an on-demand finder plus data enrichment keeps the record current.

How does pricing really work across the three?#

None of these three shows fully transparent self-serve pricing. Most modern SaaS tools do. That makes budgeting harder than it should be.

• CompanyData.com works on custom quotes tied to record volume and fields. Expect enterprise-style talks, annual commitments, and minimums. That rarely suits a small team testing a channel.
• BoldData prices per list. A targeted European contact file might cost a few hundred to several thousand dollars. It depends on size and enrichment depth. You pay again for the next campaign, so cost grows with how often you prospect.
• Kaspr uses a credit subscription with a small free tier. Paid plans unlock more reveals per month. It is the most predictable of the three for a single SDR. But heavy teams burn credits fast, and costs climb.

Compare that to a usage-based finder like Tomba's pricing: a free tier with 25 searches, Starter at $49/mo, Growth at $99/mo, and Pro at $249/mo. The difference is not just the number. It is the model. You pay for successful lookups and verifications on a schedule you can predict. You do not re-buy a decaying file or negotiate an enterprise floor.

For a fair check on any vendor's claims, cross-reference verified user reviews on G2 instead of trusting the sales deck.

When should you choose each tool?#

There is no universal winner. There is a right fit per job. Here is the decision framework.

Choose CompanyData.com when:

• You need firmographic breadth for market sizing or TAM analysis.
• You feed an account-based model that lives in a data warehouse.
• Individual contact details are somebody else's problem downstream.

Choose BoldData when:

• You run a one-off campaign in a region self-serve tools cover poorly.
• You want a hands-off "brief it and receive a file" experience.
• You accept that the data is a snapshot, not a living record.

Choose Kaspr when:

• Your SDRs live inside LinkedIn and need phone numbers now.
• European mobile coverage is a priority.
• You prospect person by person, not in bulk.

Choose a dedicated email finder + verifier when:

• Deliverable, verified work emails are the actual goal.
• You want to search by domain or name on demand and keep records fresh.
• You need predictable, usage-based pricing instead of custom quotes or per-list fees.

Notice that the last option overlaps with all three others. "Get a valid email to a real person at a target company" is the job most teams are really hiring these tools to do.

What do these three miss that a finder-plus-verifier covers?#

The recurring weakness across CompanyData.com, BoldData vs Kaspr is the handoff between "I have a company" and "I have a verified way to reach the right person there." Each tool owns one part of that chain and leaves gaps at the seams:

• CompanyData.com gives you the account but not the human.
• BoldData gives you both, once, and then the file rots.
• Kaspr gives you the human in real time. But it leans on LinkedIn as the source of truth and skews European.

A finder built around domain and name search closes the loop differently. You take the target companies you already trust. You run a company email search to surface the right contacts and patterns. Then you verify before sending. So the record is fresh at the moment of outreach, not at the moment of purchase months earlier. You can read more about how such data is sourced on Tomba's data page. Confirm each vendor's own positioning directly at kaspr.io and bolddata.nl before you commit.

The honest verdict#

Maybe you strictly need what one of these tools does best — bulk firmographics (CompanyData.com), a custom regional list (BoldData), or fast LinkedIn dials (Kaspr). If so, buy that tool for that job and don't overthink it.

But maybe you landed here because you want accurate, verified emails to reach decision-makers at your target accounts. Then none of the three is the clean answer. They are either account-level, snapshot-in-time, or LinkedIn-dependent. The workflow that actually scales is simple: define your target companies, find contacts on demand, verify, and enrich — on predictable, usage-based pricing.

That is exactly the gap the Tomba Email Finder fills. Search by domain, name, or company. Verify addresses before they ever hit your sequence. Start on a free tier of 25 searches — no custom quote, no per-list invoice, no decaying CSV. Match the tool to the job, and your cost per valid contact drops accordingly.
