CompanyData.com (BoldData) vs Apollo.io: Different Tools, Different Jobs
Your compliance team just flagged half the contacts your reps pulled from Apollo - something about GDPR and browser extension data in the EU. Meanwhile, the data team wants bulk company records for a KYB workflow, and someone suggested BoldData. Now you're staring at two products that barely overlap and trying to figure out which one to buy.
Let's be honest: BoldData and Apollo aren't competitors. They're different categories of software solving different problems. Comparing them is like comparing a census bureau to a call center - one collects records, the other makes calls.
30-Second Verdict
- Choose BoldData if you need bulk company records, compliance-grade sourcing, KYB/KYC workflows, or corporate hierarchy mapping - especially in Europe.
- Choose Apollo if you need an all-in-one outbound sales platform with sequencing, a dialer, and a built-in contact database - especially for US-focused prospecting.
- Skip both if your real problem is email accuracy and deliverability. Neither solves that alone.
BoldData at a Glance
BoldData, operating as CompanyData.com, is a company data platform - not a sales engagement tool. It pulls from official trade registers, chambers of commerce, and public records across 200+ countries. No web scraping, no browser extensions. The database covers 387M+ businesses worldwide, with overall accuracy above 95%.
Where BoldData genuinely shines is compliance-heavy use cases. The API exposes director, owner, and UBO data for KYB/KYC workflows, plus corporate hierarchy mapping across borders. Need to know who owns a subsidiary in the Netherlands and how it connects to a parent company in Singapore? This is the tool.
The review footprint is thin - a 9.2/10 on Kiyoh with 85 reviews, and BoldData says Datarade named them the "#1 company data provider." But you won't find thousands of G2 reviews to validate the product. The 2-week API trial with 1,000 searches and 100 exports is the best way to judge for yourself.
Apollo.io at a Glance
Apollo is the obvious starting point for most SMB outbound teams. The database covers 275M+ contacts, and the platform bundles sequencing, a dialer, email campaigns, and a Chrome extension into one seat. Starting around $49/user/month on annual billing, it's accessible.
Here's the thing: Apollo's data quality doesn't match its feature breadth. G2 shows 4.7/5 across 9,512 reviews, which looks great until you notice 503 reviews tagged "Inaccurate Data" and another 597 tagged "Missing Features." Independent estimates peg overall accuracy around 65%.
A Reddit user testing Apollo lists with NeverBounce reported bounce rates of 32-38%. For context, the same testing found Lusha at 22-28% and Clay's waterfall approach at 10-14%. Marketing 275M+ contacts when a third bounce is a vanity metric, and the consensus on r/sales is that you need a verification layer on top of Apollo or you're burning your domain.
Credits don't roll over, phone numbers cost 8x more than emails in credit terms, and the Organization plan requires a 3-user minimum. The free tier is generous for testing, but costs scale fast once you're committed.
Head-to-Head Comparison
| Feature | BoldData | Apollo.io |
|---|---|---|
| Data type | Company records | Contact profiles |
| Database size | 387M+ companies | 275M+ contacts |
| Data sourcing | Official registers | Web data + Chrome extension |
| Accuracy | 95%+ (vendor-reported) | ~65% (third-party est.) |
| GDPR compliance | Built on public records | Depends on use case |
| Engagement tools | None | Sequences, dialer, email |
| API | REST (hierarchy, KYB) | REST (contacts, sequences) |
| Pricing model | Bulk minimums from EUR425 | Per-seat from ~$49/user/mo |
| G2 reviews | Minimal presence | 9,512 reviews (4.7/5) |
We've tested both platforms' APIs, and the takeaway is straightforward: these tools have almost zero functional overlap. BoldData gives you company intelligence at scale. Apollo gives you a contact database wired into an outreach engine. The answer depends entirely on what job you're hiring the software to do.
BoldData gives you company records without contacts. Apollo gives you contacts that bounce 32-38% of the time. Prospeo gives you 300M+ profiles with 98% verified email accuracy - no verification layer needed on top. At $0.01 per email with a 7-day data refresh cycle, your domain stays clean and your pipeline stays full.
Stop stacking tools to fix bad data. Start with data that works.
Pricing Breakdown
BoldData Pricing
| Product | Price |
|---|---|
| Bold Lists | Minimum EUR425 for 1,000 records |
| Bold Bulk | Minimum order EUR3,000 (~100K records); typical volumes 1M+ records from EUR10,000 |
| Bold Platform | Pay-as-you-go (10 free credits) |
| Bold API | Usage-based (quote required) |
Apollo.io Pricing (Annual)
| Plan | Price/User/Mo | Mobile Credits/Mo |
|---|---|---|
| Free | $0 | 5 |
| Basic | $49 | 75 |
| Professional | $79 | 100 |
| Organization | $119 (3-user min) | 200 |
Overage credits run $0.20 each with a 250-credit minimum purchase. BoldData not publishing API pricing when you're trying to do a quick comparison is frustrating - expect typical B2B data API costs in the low hundreds to low thousands per month depending on volume.
BoldData is built for bulk buyers and data teams. Apollo is built for per-seat sales teams. If you need 50 verified emails for a Tuesday campaign, neither is ideal.
Data Quality and Compliance
This is where the comparison gets sharp.
BoldData sources from official trade registers and chambers of commerce - public records that exist regardless of anyone's terms of service. Apollo's workflow introduces compliance exposure when teams rely on its Chrome extension for EU/UK prospecting. Apollo's own support has cautioned users directly: "Apollo's Chrome extension does not automatically apply GDPR protections" for EU/UK contacts. That's not a competitor talking - that's Apollo's support team on Reddit. CEO Tim Zheng publicly acknowledged working with LinkedIn to resolve brand page restrictions after Apollo's presence went dark.
On accuracy, Apollo's ~65% overall figure and 32-38% bounce rates in real-world testing tell a clear story. If you're running outbound at any real volume, you need a verification layer on top - or a data source that doesn't require one.
Apollo is the best free-tier sales platform on the market. But "free" stops being free when a third of your emails bounce and your domain reputation tanks. The real cost of bad data is the deals you never get to pitch.
When to Choose Which
Choose BoldData when:
- You need bulk company data for analytics, enrichment, or AI/ML training
- Compliance workflows require UBO, director, and corporate hierarchy data
- European coverage from official registers is non-negotiable
Choose Apollo when:
- You need an all-in-one outbound platform with sequences, dialer, and email
- US-focused contact prospecting is the primary use case
- You want a large free tier to test before committing
The Missing Piece: Verified Contacts
Neither tool fills this gap cleanly. BoldData gives you company records - firmographics, hierarchies, compliance data - but not verified outreach-ready emails. Apollo gives you contacts, but roughly a third of them bounce in real-world testing.
If your bottleneck is deliverability, start with the basics: email bounce rate, email deliverability, and the sender reputation signals that keep you out of spam.
The article's verdict is clear: neither BoldData nor Apollo solves verified contact data. Prospeo does - 143M+ verified emails, 125M+ verified mobiles with a 30% pickup rate, and 30+ filters including buyer intent and technographics. Teams using Prospeo book 35% more meetings than Apollo users.
Fill the gap both platforms leave open - with data that actually connects.
FAQ

Not really. BoldData is a company data platform for bulk records, compliance, and enrichment. Apollo is a sales engagement platform with a contact database.

Is Apollo.io GDPR compliant?
Apollo's own support has cautioned that its Chrome extension "does not automatically apply GDPR protections" for EU/UK contacts. If GDPR compliance is critical, verify Apollo's current policies directly or consider a provider sourcing from official public records.

Prospeo delivers 98% email accuracy with a 7-day data refresh cycle, compared to Apollo's estimated ~65% overall accuracy. It covers 143M+ verified emails across 300M+ profiles, with a free tier and no contracts required.
