Datanyze vs SignalHire: Which Contact Data Tool Is Worth Your Credits?
You're comparing Datanyze and SignalHire because you don't want to pay ZoomInfo prices. Fair enough. A ZoomInfo contract can land anywhere from $15-60k/year depending on seats and modules, and most small teams don't need half of what's bundled in. Both tools promise cheaper contact data with a browser-extension workflow, but the question is whether either one delivers enough accuracy to justify the credits you'll burn through.
30-Second Verdict
Pick Datanyze if you're a small sales team that needs technographic data and you like the fact it's owned by ZoomInfo. It's cheap and simple.
Pick SignalHire if you're a recruiter or sourcer who needs a larger database and phone numbers, and you're okay paying more per month.

What Each Tool Actually Costs
Datanyze Pricing
| Plan | Monthly billing | Annual billing | Credits |
|---|---|---|---|
| Nyze Lite | Free | - | 10/mo (90 days, business email required) |
| Nyze Pro 1 | $29/mo | $21/mo | 960/yr (~80/mo) |
| Nyze Pro 2 | $55/mo | $39/mo | 1,920/yr (~160/mo) |
At 960 credits per year on Pro 1, you're paying roughly $0.26 per contact. Pro 2 on annual billing brings that down to about $0.24. Either way, you're spending around a quarter per reveal - before you factor in credits wasted on HQ numbers instead of direct dials. If you're comparing options across best sales prospecting databases, this is where Datanyze starts to look expensive.
SignalHire Pricing
| Plan | Monthly | Annual | Credits/yr |
|---|---|---|---|
| Free | $0 | - | 5 credits (10/month with extension) |
| Emails | $69/mo | $57/mo | 12,000 |
| Phones | $69/mo | $57/mo | 5,400 |
| Emails & Phones | $139/mo | $110/mo | 10,800 |
| "Unlimited" | Annual only | $167/mo | 5,000 credits/month cap |
SignalHire's cost per contact on the Emails plan works out to about $0.057--significantly cheaper than Datanyze per credit. That said, the "Unlimited Package" at $167/month isn't unlimited. A fair-usage policy caps you at 5,000 credits per month. Generous for an individual recruiter, but don't plan your workflow around infinite lookups.
Data Quality: The Numbers Neither Tool Wants You to See
SignalHire positions itself around 95%+ email accuracy, live verification, and a typical 3-5% bounce rate. G2 review themes tell a different story. "Outdated/incorrect info" and even "fraudulent information" show up as recurring negatives in G2's theme summary, alongside the usual "expensive" and "limited credits" complaints.
If you're trying to protect deliverability while still prospecting at volume, it helps to understand email bounce rate benchmarks and what they do to your domain over time.
A recruiter on r/recruiting ran a small bake-off and found SignalHire returning "older numbers and older emails"--including Hotmail addresses, which is a dead giveaway the data hasn't been refreshed recently.
Datanyze doesn't publish an accuracy claim at all. The recurring issues are specific: credits get consumed when you pull a company HQ number instead of a direct dial, APAC and India coverage is notably weak, and the Chrome extension has a history of bugs with multiple tabs open.
Here's the thing. Even with verification in the mix, you can still burn credits on reveals that don't help your workflow - old numbers, generic inboxes, wrong person, or contact details that simply don't connect. Every bounced email doesn't just waste a credit; it chips away at your sender reputation and domain deliverability, which is a cost that compounds over weeks and months in ways that are hard to reverse. If you want the mechanics, start with an email deliverability guide and then tighten your process with how to improve sender reputation.
Our take: If your deal sizes sit below five figures, you probably can't afford the hidden cost of bad data from either tool. The credits are cheap. The bounced emails and burned domains aren't.
Burning credits on stale data and HQ numbers isn't a savings strategy. Prospeo refreshes every record on a 7-day cycle - not months - and delivers 98% email accuracy with 125M+ verified mobiles at $0.01 per email.
Stop subsidizing bad data with your domain reputation.
What Real Users Say
On G2, Datanyze wins on usability. Reviewers found it easier to use and administer than SignalHire, and preferred Datanyze for quality of ongoing support. SignalHire's G2 reviews (56 total vs. Datanyze's 446) lean heavily on ease of use as a positive - 12 mentions - but "expensive" and "limited credits" each appear five times in the cons.
SignalHire's billing practices are where things get ugly. Trustpilot shows a 3.8/5 across 73 reviews, with multiple complaints about charges continuing after cancellation. On Software Advice, one reviewer reported being out nearly $500 after an annual renewal they didn't authorize. Another flagged that SignalHire's browser extension requests permissions including access to authentication data - a concern their cybersecurity team raised. The company replies to about 15% of negative Trustpilot reviews, typically within a week, which suggests awareness without urgency. Read the cancellation terms line by line before entering payment details.
The Reddit consensus on SignalHire lands at "good lookup but pricey." We've seen this pattern before with credit-based tools: they work well enough when they work, but credit economics and stale data make the total cost of ownership higher than the sticker price suggests. SignalHire's API integrations also draw complaints - one Loxo user noted the integration "does not work that well," which matters if you're building automated sourcing workflows. If you're tightening your outbound process, these sales prospecting techniques help you waste fewer credits.
Is Datanyze Still a Real Product?
ZoomInfo acquired Datanyze in September 2018 and promised continued support. That was nearly eight years ago.
The TrustRadius review corpus clusters heavily in 2017-2019, with a visible drop-off after that. On G2, reviewers actually prefer SignalHire's product direction over Datanyze's - a telling signal when the smaller tool wins on roadmap confidence. Datanyze feels like a product coasting on the ZoomInfo brand. It still works for basic technographic lookups and cheap contact reveals, but there's little evidence of meaningful investment since the acquisition. If you're building a prospecting workflow you'll rely on for the next two years, that stagnation matters.
If technographics are the main reason you're here, it’s worth grounding the difference between firmographic and technographic data before you commit to a tool.
Datanyze vs SignalHire: The Verdict
Pick Datanyze if you're a solo rep or small team that needs technographic data and your monthly volume is under 160 lookups. At $21-39/month, it's hard to beat on price alone. If you want to sanity-check the tiers, see Datanyze Pricing.
Pick SignalHire if you're a recruiter or sourcing team that needs a larger database and phone numbers. The 850M+ profile database dwarfs Datanyze's scope, and the per-credit cost is lower on the Emails plan. Just read the billing terms carefully and vet those extension permissions. For the plan breakdown, see SignalHire Pricing.
Let's be honest - neither tool solves the core problem. Both have documented accuracy gaps that eat into the cost savings you came here looking for. If deliverability and domain health aren't negotiable for your team, Prospeo's email finder runs on a 7-day data refresh cycle with 98% email accuracy and 125M+ verified mobile numbers. The free tier gives you 75 verified emails per month plus 100 Chrome extension credits, no credit card required. One of our customers, Stack Optimize, built to $1M ARR while keeping client deliverability above 94% and bounce rates under 3%--that's the kind of reliability that compounds.
If you're evaluating other sourcing-focused tools, compare notes with our SignalHire email finder breakdown.
Both Datanyze and SignalHire leave you guessing on data freshness. Prospeo's 5-step verification and weekly refresh cycle mean fewer bounces, healthier domains, and credits that actually convert to conversations.
Your sender reputation deserves better than a coin flip.
FAQ
Is Datanyze still being updated in 2026?
ZoomInfo acquired Datanyze in 2018, and the review corpus has thinned dramatically since 2019. G2 reviewers prefer SignalHire's product direction over Datanyze's roadmap. It still functions for basic technographic lookups, but treat it as a maintenance-mode tool with limited future investment.
Is SignalHire's unlimited plan really unlimited?
No. The $167/month annual plan includes a fair-usage policy capping usage at 5,000 credits per month. That's generous for individual recruiters, but teams doing high-volume sourcing will hit that ceiling within the first two weeks.
Can I use Datanyze or SignalHire for phone numbers?
Datanyze includes phone numbers in its credits but frequently returns company HQ lines instead of direct dials. SignalHire has a dedicated Phones plan at $57/mo annual with 5,400 credits per year and better mobile coverage. For verified direct dials at scale, Prospeo's mobile finder covers 125M+ verified mobile numbers with a 30% pickup rate across all regions.
