Adapt.io vs CompanyData.com (BoldData): A Comparison That Shouldn't Exist
On Slashdot, there's a comparison page for Adapt vs BoldData. It has one rating and zero ratings. Reddit discussion is thin for Adapt.io, and we couldn't find usable threads for CompanyData.com either. That tells you everything about this matchup: almost nobody is comparing these two, because they don't do the same thing.
Adapt.io is a sales prospecting platform. CompanyData.com (formerly BoldData) is a trade register data provider built for KYB and compliance. BoldData rebranded to CompanyData.com on September 11, 2025 - same team, same data, new name.
But the comparison exists, so let's make it useful.
30-Second Verdict
Choose Adapt.io if you need contact emails and some phone data for sales prospecting on a self-serve budget.
Choose CompanyData.com if you need official trade register data for KYB, compliance, or company enrichment - not prospecting.
Skip both if you need verified emails and direct dials for outbound at scale. Prospeo covers 143M+ verified emails and 125M+ verified mobiles with no annual contracts and a free tier to test.

The numbers look comparable until you realize what's behind them. Adapt.io's 150M+ contacts are people with emails and phones for outbound. CompanyData.com's 400M+ companies are legal entities with registration numbers and VAT IDs. Different data for different jobs entirely.
Adapt.io - What You Get
Adapt.io is a straightforward B2B prospecting tool. You search by job title, department, company size, and industry, then pull contact emails and phones. On G2, reviewers consistently praise usability - the pros/cons aggregation shows 71 mentions for ease of use.
Self-serve plans start at $49/month for 500 email credits, scaling to $99/month for 1,000 email credits and 100 phone credits. The free plan gives you 25 contacts/day with 25 email credits and 25 data enrichment credits.
Here's the thing: credit limits are the number-one complaint on G2, with 34 mentions. At 500 emails/month on the $49 plan, you'll burn through credits in the first week of any real outbound campaign. Email accuracy issues also surface - 14 G2 mentions tied to incorrect emails, which turns prospecting into a credit-management exercise where you're paying for bad data. We've seen this pattern across multiple tools in this price range, and it's frustrating every time.
If you're running cold outreach, it also helps to understand email bounce rate benchmarks and what "good" looks like before you scale volume.
Adapt.io's credit limits and email accuracy issues mean you're paying for data that bounces. Prospeo delivers 98% email accuracy with a 7-day refresh cycle - so every credit returns a real, reachable contact. At $0.01/email with 143M+ verified addresses, you stop managing credits and start booking meetings.
75 free emails/month. No credit card. No contracts. No bounces.
CompanyData.com - What You Get
CompanyData.com isn't a prospecting tool. It's company data infrastructure.
The API covers 400M+ companies across 200+ countries, sourced from official local registers - Companies House (UK), KvK (Netherlands), INSEE (France), Handelsregister (Germany), and similar trusted sources. No scraping, no estimates, no AI-generated records.
The data is KYB/KYC-oriented: registration numbers, VAT numbers, legal status, incorporation dates, directors, and UBO data. The legacy BoldData site also describes the dataset as including 175M phone numbers but only 48M email addresses - about 12% email coverage against a 400M-company footprint. That ratio alone tells you this isn't built for cold email.
API access is usage-based, with entry packages starting around EUR425 for limited datasets. For bulk exports, the Bold Bulk offering starts at EUR10,000 with a typical minimum of ~1 million company records. The free API test key runs two weeks and includes 1,000 company lookups plus 100 data exports, but it's only available to registered businesses with an active website.
If you're evaluating CompanyData.com for outbound prospecting, you're looking at the wrong tool entirely. It's compliance infrastructure that happens to have some contact data on the side.
What Do You Actually Need?
The confusion here comes from people searching for "company data" and landing on a compliance provider when they wanted prospecting contacts. Quick decision framework:
Sales prospecting and outbound emails - Adapt.io gets you closer, but credit limits and email accuracy issues create friction at scale.
Company data, KYB, and compliance - CompanyData.com is purpose-built. Official register data, UBO lookups, VAT verification. No prospecting tool touches this.
Verified contact data at scale - Neither tool is ideal. CompanyData.com's 48M emails across 400M+ companies is tiny for outbound, and Adapt.io's credit limits leave a gap once you're running real volume.

Verified Emails at Scale
In our testing, teams using Prospeo book 26% more meetings compared to ZoomInfo and 35% more compared to Apollo - largely because fresher, more accurate data means fewer bounces and more live conversations. When your bounce rate drops from 35% to under 4% (as it did for Meritt, who tripled their pipeline from $100K to $300K/week), the ROI math stops being theoretical.
If you're optimizing outbound performance, it helps to track lead generation metrics and pipeline health alongside deliverability.
Neither Adapt.io nor CompanyData.com gives you verified emails and direct dials at outbound scale. Prospeo covers both - 143M+ verified emails and 125M+ verified mobiles across 300M+ profiles, with 30+ filters including buyer intent and technographics. Teams using Prospeo book 35% more meetings than Apollo users.
Stop stitching two tools together for what one platform already does.
FAQ
Is BoldData the same as CompanyData.com?
Yes. BoldData rebranded to CompanyData.com on September 11, 2025. Same team, same data, same Amsterdam headquarters. Any "BoldData" reference you find online is the legacy name - all products and APIs carry over unchanged.
Can I use Adapt.io and CompanyData.com together?
You can - Adapt.io for contact prospecting, CompanyData.com for company enrichment and KYB verification. But managing two platforms and two budgets for workflows a single tool could handle is rarely worth the overhead for most sales teams.
What's the best tool for verified B2B emails in 2026?
Prospeo leads for verified email accuracy at scale: 143M+ verified emails, 98% accuracy, and a 7-day refresh cycle. At ~$0.01 per email with a free tier, it covers the outbound use case where both Adapt.io and CompanyData.com fall short.
Who should choose CompanyData.com over Adapt.io?
Compliance teams, fintech companies running KYB checks, and data teams needing official trade register records across 200+ countries. If your workflow involves VAT verification, UBO lookups, or legal entity screening - not sales outreach - CompanyData.com is the right pick.
