Datanyze vs LeadGibbon: Which Budget Prospecting Tool Is Worth It?
B2B contact data decays at roughly 22.5% per year. That means nearly a quarter of any database is wrong before you even hit "export." So the real question when comparing Datanyze vs LeadGibbon isn't which one's cheaper - it's which gives you data that actually works.
30-Second Verdict
- Pick Datanyze if you want a lightweight Chrome extension backed by a 120M-contact database with direct dials and emails.
- Pick LeadGibbon if you want high email volume on a budget - 1,000 verified emails for $39/mo - and you live in Google Sheets.
- Skip both if accuracy matters more than price. Prospeo delivers 98% verified emails from 300M+ profiles with a 75-email free tier, which is more generous than either tool offers.
Side-by-Side Comparison
| Datanyze | LeadGibbon | |
|---|---|---|
| Database size | 120M contacts | ~20M contacts |
| Email accuracy | Undisclosed | 99% confidence threshold (emails below that are free) |
| Free tier | 10 credits/mo | 15 credits/week |
| Starter price | $29/mo (80 credits) | $39/mo (1,000 verified emails) |
| Cost per contact | ~$0.36/credit | ~$0.039/email |
| Phone numbers | Available (credit-based reveal) | Included (25 on Basic plan) |
| G2 rating | 4.1/5 (446 reviews) | 4.3/5 (11 reviews) |
| Data refresh | Undisclosed | Real-time |
| Best for | Simple contact reveals in your browser | Email volume on a budget |

LeadGibbon's higher G2 score comes from 11 reviews - hardly a meaningful sample. Datanyze's 446 reviews carry far more weight. Also worth knowing: LeadGibbon includes all features on every plan, while Datanyze gates capabilities by tier.
Pricing Breakdown
Datanyze runs three plans: Nyze Lite (free, 10 credits/month for 3 months with a business email signup), Nyze Pro 1 ($29/month, 80 credits), and Nyze Pro 2 ($55/month, 160 credits). One credit unlocks one contact reveal - email and/or direct dial when available - so Nyze Pro 1 lands around $0.36 per reveal.
If you're comparing credit-based tools, it helps to understand how data enrichment and verification typically get priced across vendors.

LeadGibbon's $39/month Basic plan gives you 1,000 verified emails plus 25 phone numbers, roughly $0.039 per email. The Pro plan ($99/month, 10,000 verified emails) drops that to about $0.01/email. Phone numbers come with each plan, but in much smaller quantities than emails. Credits don't roll over.
Here's the thing: if your outbound motion is email-first and average deal sizes sit below $15k, LeadGibbon's per-email economics crush Datanyze. But the moment you need phone numbers at any real volume, Datanyze becomes the simpler buy.
If you're building a broader outbound stack, these sales prospecting techniques can help you decide when data volume matters more than precision.

Datanyze charges $0.36/credit with no accuracy benchmarks. LeadGibbon's reviewers recommend pairing it with a separate verification tool. Prospeo gives you 98% verified emails from 300M+ profiles at ~$0.01 each - with a 7-day data refresh cycle, not undisclosed or "real-time" that still serves stale records.
Stop paying twice - once for data and once to verify it.
Data Quality Reality Check
We've tested both extensions, and the accuracy gap becomes obvious after about 50 contacts.
If you're seeing bounces, it's usually a list hygiene issue first - use these email bounce rate benchmarks to sanity-check what “normal” looks like.

Datanyze has the larger database - 120M contacts, 48M direct dials, 84M emails. Reddit users on r/b2b_sales call it "best bang for the buck" for contact reveals. But there are no published accuracy benchmarks, and G2 flags the Datanyze profile as inactive for over a year. That's not reassuring.
LeadGibbon is dead simple - search, enrich, export to Sheets with 20+ data columns including SIC/NAICS codes. Support is responsive per G2 reviewers. The problem: multiple reviewers report old emails and guessed formats. One Capterra reviewer explicitly recommended pairing LeadGibbon with a separate verification tool because accuracy "isn't as high as more expensive brands."
When users of your data tool recommend buying a second tool to verify the first one's output, that's a red flag. If you want a quick overview of options, start with these free lead generation tools and then layer in verification.
Product Viability Concerns
ZoomInfo acquired Datanyze in 2018. The Chrome extension still works, but G2 flags the profile as inactive for over a year and there's no public roadmap. All signs point to maintenance mode.
There's also settlement-notice chatter online tied to an alleged Illinois Right of Publicity Act issue, referencing a period from Feb 2022 to Dec 2024. Not a great look for a data provider.
LeadGibbon's risk is different: obscurity. Eleven G2 reviews, three on Capterra, and a single Trustpilot review alleging GDPR issues. You're betting on a tool with minimal community validation. For teams that need vendor stability - say, for a 12-month outbound program - that's a real concern.
If you're evaluating vendors for a longer program, it can help to map the tool into your lead generation workflow so you know what breaks when data quality slips.
A Stronger Alternative to Both
Both tools share the same fundamental problem: stale or guessed data that forces you to bolt on a verification service. We've seen this pattern repeatedly with budget prospecting tools, and it's why our team built Prospeo differently.
If you're weighing other databases too, this roundup of sales prospecting databases is a useful baseline.

Beyond raw email data, you get 125M+ verified mobile numbers (30% pickup rate), 30+ search filters including buyer intent and technographics, and native integrations with Salesforce, HubSpot, Instantly, and Clay. Let's be honest - at the same price point as LeadGibbon, that's a different league entirely.
If you’re using Clay heavily, this Clay list building guide breaks down real workflows and costs.


Neither Datanyze nor LeadGibbon comes close on phone numbers. Datanyze caps at 48M direct dials behind expensive credits. LeadGibbon gives you 25 per month. Prospeo delivers 125M+ verified mobile numbers with a 30% pickup rate, plus 30+ search filters including buyer intent and technographics - all starting free.
75 free verified emails per month. No credit card. No catch.
Common Questions
Is Datanyze still actively developed?
ZoomInfo acquired Datanyze in 2018 and the Chrome extension still functions, but G2 flags the profile as inactive for over a year with no public roadmap. All signs point to maintenance mode - don't expect new features or data improvements.
Does LeadGibbon verify emails before charging credits?
LeadGibbon provides emails below a 99% deliverability threshold for free via its extension and enricher. That said, multiple G2 reviewers still report outdated or guessed addresses, suggesting the verification layer misses a meaningful percentage of bad data.
How do these tools compare on phone number coverage?
Datanyze claims 48M direct dials revealed via credits. LeadGibbon includes 25 phone numbers on its Basic plan. Prospeo offers 125M+ verified mobile numbers with a 30% pickup rate - significantly larger coverage than either budget option.
