Datanyze Review

Datanyze is a Chrome extension, not a platform: install it, browse LinkedIn or a company site, and it surfaces emails and direct dials on the page for a credit. That narrow scope is the whole pitch — a cheaper, lighter alternative to full sales-intelligence suites. This review checks that pitch against the vendor's own pricing math and against what independent reviewers and Reddit threads actually say, which turns out to be a more complicated story than the marketing page.

Verdict at a glance

What kind of tool is Datanyze?

Datanyze is a browser-based contact-data extension owned by ZoomInfo, which acquired the company in September 2018 for roughly $15 million. It doesn't try to be a CRM, a sequencer, or an intent-data platform — it does one thing: when you're looking at a LinkedIn profile or a company website, it shows you that person's email address and direct dial, deducted from a monthly credit balance. Datanyze's own market-share and technographic reports (one of its original products before the ZoomInfo acquisition) still live on the site as a secondary content asset.

The vendor claims coverage of about 84 million email addresses, 63 million direct dials, and 120 million contacts, along with a data-accuracy guarantee and a claim of full GDPR and CCPA compliance backed by "automated machine learning" and human verification. Those are vendor claims, not independently audited figures, and the third-party evidence below complicates the accuracy and compliance story.

How it works

Setup is genuinely fast: install the Chrome extension, and credits are available the moment you sign up (the free Nyze Lite tier needs no credit card). Datanyze defines a credit plainly — one credit equals one contact information reveal, and a single credit unlocks everything available for that person (phone and email together), not a separate charge per field. On a LinkedIn company page listing all employees, Datanyze can surface contact info for the whole list at once rather than one profile at a time, which is the main efficiency case for teams doing outbound prospecting.

What it doesn't do: G2's own integration listing for Datanyze shows exactly one integration, LinkedIn Sales Navigator. There's no native CRM sync or sequencer connection — you export what you find and move it manually. The features page also lists team credit-pooling and "icebreaker" prompts (personalized conversation starters) as coming soon, meaning the multi-seat and personalization angles marketed on the homepage aren't fully live yet.

Datanyze pricing (2026)

The hidden cost here isn't an add-on fee, it's the billing term. Datanyze headlines the annual price ($21, $39) on its pricing page, but if you don't want to commit for a year, the real monthly-billed price is $29 and $55 respectively — for the identical credit allotment. That's roughly 38–41% more per credit than the advertised number, which is exactly the kind of framing worth checking before you sign up expecting the sticker price.

A second real-cost detail buried in the FAQ, not the pricing table: cancel your plan and any contacts you already revealed get locked again until you resubscribe. You keep access through the end of the paid period, but the data doesn't stay unlocked afterward — worth knowing if you're testing the tool for a short project rather than an ongoing subscription.

On the plus side, cancellation itself is self-serve (no email-support back-and-forth to cancel), which contradicts some of the complaints discussed below.

What users say

The third-party evidence on Datanyze is unusually split across platforms, which is itself the most useful finding here.

G2 shows a 4.1-out-of-5 rating from 447 reviews — a meaningful sample size for this category. That said, the profile flagged that it had gone two months without a new review at the time of this check, and G2 gates individual review text behind a login wall, so the specific pros and cons behind that score aren't independently readable without an account.

Trustpilot tells a very different story: 1.9 out of 5, rated "Poor," from 17 reviews on an unclaimed profile. The sample is small, but the complaints are consistent and specific rather than generic. Multiple reviewers say their own information is wrong ("almost all the information they provide on a company is wrong," one wrote), several describe customer service as effectively unreachable when trying to cancel or dispute a charge, and a cluster of reviewers say Datanyze published their personal LinkedIn and business contact details without their consent — not as a customer complaint about data they bought, but as private individuals who found themselves listed in the database. A separate, independently repeated complaint: the site reportedly doesn't detect Firefox correctly and pushes an unsupported-browser message to real Firefox users.

Reddit corroborates several of these Trustpilot themes from an entirely different angle. In r/overemployed and r/privacy threads, people describe searching their own name and finding a Datanyze profile listing prior jobs they never disclosed to the tool, with one user describing the same removal issue recurring with ZoomInfo after they thought it was resolved, since the two companies share data and users found the affiliation confusing. Others report that opt-out requests, including ones routed through professional removal services, don't reliably stick. The Firefox-detection complaint shows up independently in r/firefox as well, which supports it being a real, longstanding bug rather than an isolated Trustpilot review. On the positive side, a r/b2b_sales thread has a rep calling Datanyze the best low-cost option they'd found for basic contact lookups, so the sentiment isn't uniformly negative — it splits fairly cleanly along the same buyer-versus-bystander line as the review platforms.

The most concrete data point is a real legal filing: Green v. Datanyze, LLC (U.S. District Court, Northern District of Illinois, Case No. 23-cv-1605), which alleges Datanyze violated the Illinois Right of Publicity Act by using individuals' names and business contact information to advertise its subscription service without their consent. Datanyze denied the allegations; a motion to dismiss was denied in January 2024 with a hearing set for the following month. Reddit's r/Scams community separately discussed settlement-notice emails referencing a purported multi-state class settlement tied to this dispute, but commenters in that thread could not independently confirm a settlement had been finalized — treat those specific notices with the same caution the original posters did, distinct from the underlying lawsuit itself, which is a matter of public record.

Pros and cons

Pros

• Genuinely cheap per-contact pricing at the annual rate, especially on Nyze Pro 2
• One credit reveals both email and direct dial, not a per-field charge
• Fast setup — a Chrome extension, not a platform onboarding
• Free 90-day trial with no credit card required
• Self-serve cancellation through account settings
• 447 reviews and a 4.1/5 average on G2

Cons

• Monthly (non-annual) billing costs roughly 38–41% more per credit than the headline price
• Revealed contacts lock again after cancellation until you resubscribe
• Trustpilot rating of 1.9/5 across 17 reviews, with recurring accuracy and consent complaints
• Subject of a 2023 federal lawsuit alleging non-consensual use of people's identifying information
• Only one listed integration (LinkedIn Sales Navigator) — no native CRM or sequencer sync
• Team pooling and icebreaker features are marketed but still listed as coming soon

Datanyze alternatives

Datanyze competes in the B2B contact-data category, where nearly every player has its own accuracy and consent debates — it's worth comparing more than one before you commit credits to any of them.

• Apollo — a much broader platform (search, sequencing, and enrichment together) at a similar or lower entry price point.
• ZoomInfo — Datanyze's parent company; a far larger enterprise-grade database and platform at enterprise pricing.
• Lusha — a comparable Chrome-extension-first contact tool, similarly priced and similarly credit-based.
• LeadIQ — extension-based capture with stronger native CRM and sequencer sync than Datanyze offers.
• Clearbit (now part of HubSpot) — company and firmographic enrichment rather than a contact-reveal extension; a different use case but a common alternative search.
• ContactOut — another browser-extension contact finder in the same low-cost bracket, also carrying a low Trustpilot score (1.3/5 in the same "people also looked at" comparison set).

If the appeal is specifically the lightweight, cheap-per-credit browser workflow, Lusha and ContactOut are the most direct comparisons. If you actually need sequencing or CRM sync built in, Apollo or LeadIQ remove a manual export step that Datanyze doesn't.

Who should use Datanyze — and who shouldn't

Good fit: individual reps or small teams who already prospect manually on LinkedIn and just want a cheap way to reveal contact details without buying a full platform; budget-conscious buyers comparing extension-based tools on price per credit; anyone testing the category who wants a genuine no-card 90-day trial before spending anything.

Poor fit: teams that need CRM or sequencer integration built in rather than manual export; buyers who weight third-party trust signals heavily and want a clean review record — the Trustpilot and Reddit pattern here is more pointed than most tools in this category; and anyone uncomfortable with a vendor that's currently the subject of active litigation over how it sourced and published personal contact information.
