CompanyData.com (BoldData) vs LeadRocks: Different Tools for Different Jobs
Nobody tells you this upfront: comparing CompanyData.com (BoldData) vs LeadRocks is like comparing a commercial real estate database to a cold email tool. They both get filed under "B2B data provider," but they solve fundamentally different problems. One sells firmographic company records sourced from national trade registers and chambers of commerce. The other sells contact-level emails and phone numbers for outbound prospecting.
Here's the thing - if you're shopping for a B2B data tool and these two ended up on the same shortlist, there's a good chance you haven't nailed down what you actually need yet. Let's sort that out.
30-Second Verdict
Pick CompanyData.com (BoldData) if you need firmographic company records - legal entities, corporate hierarchies, and trade register-sourced data across 200 countries. Bold Lists starts at a EUR 425 minimum (1,000 contacts). This is enterprise data procurement, not self-serve prospecting.
Pick LeadRocks if you want a cheap contact-level database with emails and phone numbers and you're okay with serious accuracy tradeoffs. Free tier available, paid plans from $29/mo.
CompanyData.com (BoldData) Overview
BoldData rebranded to CompanyData.com in late 2025, but the product hasn't changed: a firmographic data provider covering 380M companies across 200 countries. The key differentiator is sourcing - they emphasize "no scraping" and build datasets rooted in trusted local sources like national trade registers and chambers of commerce.
The product line breaks into several tiers:
- Bold Lists - custom-built mailing lists, minimum order EUR 425 (1,000 contacts)
- Bold API - real-time company lookup and integration, including directors and owners/UBOs
- Bold Bulk - enterprise-scale exports with a minimum order of EUR 3,000 (example: ~100,000 addresses); bulk datasets typically start at 1M company records with pricing from EUR 10,000
- Bold Enrichment - cleaning, completing, and verifying CRM/company databases (see data enrichment options)
- Bold Hierarchies - corporate structure mapping for parent/subsidiary relationships
Pricing is largely custom and quote-based, though CompanyData.com publishes minimums and examples for several offerings.
One downside we noticed: there's no meaningful public review footprint on major review platforms, which makes independent quality assessment difficult. BoldData claimed the #1 spot on Datarade, but beyond that, third-party validation is thin. For a tool with EUR 425+ minimums, that's a real risk for buyers trying to do due diligence. If you need a self-serve prospecting database with verified emails and direct dials, CompanyData.com isn't built for that - it's a company data and hierarchy provider, and any contact or email data gets delivered as part of custom datasets rather than a lightweight outbound workflow. (If you're evaluating vendors in this category, start with a broader list of B2B company data providers.)
LeadRocks Overview
LeadRocks positions itself as a budget-friendly B2B contact database with 100M+ records across 150+ countries. It's the opposite end of the spectrum from CompanyData.com - self-serve, subscription-based, and built for outbound prospecting. The platform includes a Chrome extension for enriching contacts from professional profile pages and exporting search results to CSV.
The pricing runs across five tiers:
| Plan | Monthly Cost | Credits/Month | Extras |
|---|---|---|---|
| Free | $0 | 50 | None |
| Starter | $29 | 1,000 | None |
| Growth | $145 | 5,000 | None |
| Professional | $290 | 10,000 | Unlimited users; 1 email automation seat; 10K email verification credits |
| Enterprise | $580 | 20,000 | Unlimited users; 2 email automation seats; 20K email verification credits |
One credit gets you all contact details for one person. Email automation seats and email verification credits only kick in at the Professional tier ($290/mo), which is a steep gate for teams that need those features on day one. (If you're building an outbound stack, compare other SDR tools and outbound lead generation tools too.)
LeadRocks gained traction through an AppSumo lifetime deal - $89 one-time for 7,500 credits/month (now sold out) - which explains its 365 reviews at 4.5/5 on AppSumo. The LTD crowd drives most of its public review footprint. Reddit threads asking about LeadRocks draw almost no replies, which tells you something about the tool's mindshare in the cold email community.
The biggest limitation: LeadRocks confirms on its own site that it has zero CRM integrations. That means CSV exports and manual workflow glue. For teams running any kind of automated pipeline, that's a dealbreaker. (If you're trying to connect outreach tool to CRM, this is where the gaps show up fast.)
LeadRocks users report 18-53% email validity. CompanyData.com doesn't even offer self-serve contact data. Prospeo gives you 300M+ profiles with 98% verified email accuracy, 125M+ direct dials, and 30+ search filters - all self-serve from $0.01/email.
Stop choosing between overpriced firmographics and unreliable contacts.

These tools don't really compete. One gives you company records for enterprise data needs. The other gives you contact details for outbound. The comparison only makes sense if you're asking "which B2B data tool should I buy?" without knowing what kind of data you need yet.
If your deal sizes sit below five figures and you're running outbound, neither of these should be your first choice. CompanyData.com is overkill for most outbound motions. LeadRocks is cheap, but the data quality can cost you more in wasted rep time than you save on the subscription. (For better outbound fundamentals, see these sales prospecting techniques.)
Data Quality - What Users Report
LeadRocks has unusually concrete public feedback on AppSumo, and some of it is brutal.
One reviewer exported 17,775 contacts labeled as "Rhode Island business owners." Only 56 were actually in Rhode Island. After running the remaining emails through an external verifier, roughly 53% came back valid. Another batch of 4,828 emails yielded just 873 valid addresses - an 18% hit rate. We've tested a lot of B2B data tools over the years, and those numbers are among the worst we've seen published publicly.
The built-in email verifier doesn't help much either. Multiple reviewers say it returns every email as "unknown status," which makes it functionally useless for list cleaning. You'd need to pay for an external verification tool on top of your LeadRocks subscription, eating into that budget-friendly positioning fast. (If you're troubleshooting deliverability, start with email bounce rate benchmarks and a proper email deliverability guide.)
On the CompanyData.com side, there's simply no comparable public review dataset to evaluate. In our experience, tools with high minimums and minimal independent reviews are the riskiest purchases in B2B data. You're buying blind.
When Neither Tool Fits
Look - if what you actually need is accurate contact-level data for outbound, not firmographic records, not an 18% hit rate, there's a gap neither tool covers well.
The difference in verification is structural. Prospeo runs a proprietary 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering. That's why teams like Snyk saw bounce rates drop from 35-40% to under 5% after switching, while generating 200+ new opportunities per month across 50 AEs. Compare that to LeadRocks' reported 18-53% validity in real-world exports and the gap becomes hard to ignore. (If you're evaluating verifiers, compare Bouncer alternatives and read up on spam trap removal.)
Final Verdict
Three different tools, three different jobs.
Enterprise firmographic and hierarchy data - CompanyData.com (BoldData). You're paying published minimums like EUR 425 for trade register-sourced company records and hierarchies. This is for data teams, compliance, and KYC, not day-to-day outbound prospecting.
Budget contact prospecting with accuracy tradeoffs - LeadRocks. The free tier and low entry price make it tempting, but go in with eyes open about data quality and the lack of CRM integrations. The public review numbers don't hold up well enough for high-volume outbound.
Zero CRM integrations from LeadRocks. Quote-based pricing from CompanyData.com. Prospeo connects natively to Salesforce, HubSpot, Instantly, and more - with a 7-day data refresh cycle and 92% API match rate. No contracts, no sales calls.
Get enterprise-grade B2B data without enterprise friction or pricing.
