Exact Data vs Wiza: Which B2B Contact Tool Wins in 2026?

Exact Data vs Wiza is a comparison that trips up a lot of outbound teams. On a pricing page the two look similar. Under the hood they are built on opposite foundations. One sells you a finished file. The other reads LinkedIn live, on demand. Pick the wrong one and you burn a quarter of your data budget on records you can't use.

TL;DR

• Exact Data is a list broker. You buy a static CSV of contacts, filtered by industry, title, geography, and consumer traits. Good for volume. Bad for freshness.
• Wiza is a LinkedIn-native scraper. Point it at a Sales Navigator search. It returns verified work emails and phones for those exact profiles.
• They are not real competitors. Exact Data competes with ZoomInfo-style databases. Wiza competes with Apollo, ContactOut, and Lusha.
• Freshness decides it. B2B contact data goes stale by roughly 25–30% a year. A static file starts decaying the moment it's exported.
• Most teams need a third thing: an on-demand API that finds and verifies an email at the moment you send, not weeks earlier. That's where a tool like Tomba's email finder fits alongside either one.

What Are Exact Data and Wiza, Actually?#

Think of it like buying groceries. Exact Data is the bulk warehouse store. You walk out with pallets at a low unit price, but some of it is near expiry and you can't return it. Wiza is the farmer's market. You pick the exact items you want, today, and pay more per unit for that freshness.

Exact Data (exactdata.com) is a Chicago-based data broker. It has sold list files since the early 2000s. Its core product is a licensed database you can download. Records are sorted by business and consumer traits: SIC/NAICS code, employee count, revenue band, and job function. The consumer arm adds fields like homeowner status and purchase intent. You define a count, they quote a price, you get a file. Some plans allow repeat use. Many are single-use only.

Wiza (wiza.co) started as a Chrome extension. It turned a LinkedIn Sales Navigator search into an exportable contact list. Today it's a full prospecting platform with a contact database, an extension, an API, and CRM push. The differentiator has not changed. The data is tied to a live LinkedIn profile, so job titles and companies reflect what the person says about themselves right now.

That one design choice — warehoused file versus live profile scrape — drives every other tradeoff below.

Exact Data vs Wiza: How Do They Compare Head-to-Head?#

The pricing rows need a caveat. Exact Data quotes per order, not per seat. So a 50,000-record file can cost less per contact than any credit-based tool. But you pay for records you will never touch. Wiza's credit model works the other way. You pay only for contacts you actually pull, at a much higher price each.

Which One Has Better Data Accuracy?#

In an Exact Data vs Wiza accuracy test, neither wins outright. They fail in different directions. That matters far more than a single accuracy percentage.

Exact Data's failure mode is staleness. A list file is a snapshot. Say the file was built in Q1 and you mail it in Q3. Every job change, every acquisition, and every layoff in between is invisible to you. Industry research puts B2B data decay between 22% and 30% a year. Gartner and other analyst firms call contact decay the biggest driver of CRM data quality complaints. On a 12-month-old file, about a quarter of your records are wrong before you press send.

Wiza's failure mode is guesswork. LinkedIn does not publish work email addresses. So Wiza works out the company's email pattern and builds the most likely address. Then it runs SMTP-level validation. When the pattern is clean (first.last@company.com) and the mail server answers honestly, this works very well. Catch-all domains break it. They accept every address, whether or not the mailbox exists, so a "valid" result means nothing. This is not a Wiza-specific weakness. It hits every tool that guesses at patterns. That's why a dedicated catch-all verifier belongs in the stack no matter which vendor you buy from.

Practical read: Wiza's title and company data beats Exact Data's on any list older than six months. It reads a profile the person keeps up to date themselves. But Exact Data goes deeper on company detail — revenue bands, SIC codes, physical addresses — than anything you can scrape from a LinkedIn profile.

How Should You Evaluate Either Tool Before Buying?#

Run the same five-step test on both. It takes an afternoon. It can save you a quarter of your budget.

1. Build a 100-record known-truth sample. Use contacts you have already verified: current customers, past deals, people you emailed this month. Now you have ground truth.
2. Request the same 100 from each vendor. Exact Data will run a test file for a serious buyer. Wiza's free tier covers this directly.
3. Measure match rate, not accuracy. Match rate is how many of your 100 the vendor could return at all. A tool with 95% accuracy on 40% coverage is worse than 85% on 90% coverage.
4. Re-verify everything independently. Never trust a vendor's own validity flag. Run the export through a third-party email verifier and compare the two verdicts. The gap is your real error rate.
5. Check the job-change rate. For each record, compare the returned title to the person's current LinkedIn headline. That percentage is your staleness number. It predicts your bounce rate.

Step 4 is where most evaluations go wrong. Vendors mark records valid using their own logic. Self-graded homework earns high marks everywhere.

Is Wiza Worth It Over a Cheaper Email Finder?#

Sometimes. It depends on one thing. Are you paying for the LinkedIn link, or just for emails?

Wiza's real product is the bridge between a Sales Navigator search and a usable contact file. Maybe your whole prospecting motion starts in Sales Navigator. You build lists there. You filter there. Your ideal customer is defined by LinkedIn attributes. Then Wiza's price is justified, because nothing else makes that jump as cleanly. If you live in LinkedIn, read through the tradeoffs in a Wiza alternative breakdown before you sign an annual plan.

But say you already have names and domains. They came from a CRM export, a conference list, a scraped directory, or a partner's referral sheet. Now you're paying Wiza's premium for a LinkedIn step you don't need. A domain-first tool is cheaper and faster here. Feed those names and domains into a domain search or a bulk finder. You get the same emails without the profile scrape.

Here's the pricing math laid out plainly:

Note the last row. If you buy from Exact Data — or any list broker — budget for verification separately. Dropping a purchased file straight into your sequencer is the fastest way to torch a sending domain.

What About Deliverability Risk?#

This is the part both vendors' marketing pages skip.

Static list files carry three risks that stack up. First, bounce rate. Decayed records hit dead mailboxes, and inbox providers read a high hard-bounce rate as a spam signal. Second, spam traps. These are recycled addresses that providers reuse to catch senders working from old purchased data. One trap hit can put your domain on a blocklist. Third, consent. Purchased B2C data carries real legal exposure under GDPR and, for US consumer records, a growing list of state privacy laws.

Wiza's live-scrape model cuts bounce and trap risk a lot. It isn't handing you addresses compiled two years ago. It does not fix the catch-all problem, though. And it does not answer consent questions on its own.

Whichever you pick, follow the same order: acquire, verify, warm, send. Skipping the verify step saves a few cents per record. It costs far more in email deliverability damage. For an outside view, G2's data provider category has enough reviews to be useful. Read it directionally, since review incentives skew toward recent buyers.

When Does Neither Tool Fit?#

There are three cases where you should stop shopping in this category.

You need coverage outside LinkedIn's footprint. Wiza is only as good as LinkedIn adoption in your market. In manufacturing, trades, local services, and much of APAC, the decision-makers you want aren't there. Exact Data covers part of that gap, but with the freshness penalty above.

You need contacts at the moment of intent. A visitor lands on your pricing page. A prospect replies to a newsletter. A name shows up in a webinar signup. A static file can't help, and neither can a batch scrape. You need an API call that resolves a person to a verified email in under a second. That's a different product category, closer to data enrichment than list buying.

Your volume is small and your targeting is precise. Say you send 200 well-researched emails a month to named accounts. You don't need either platform. You need a per-lookup finder and good research. Paying a platform fee for capacity you won't use is the most common overspend here.

This market also has more honest players than its "buy a list" reputation suggests. BookYourData, for example, sells pay-as-you-go B2B lists with a per-record accuracy guarantee and no subscription. That's a genuinely different model from both Exact Data's quote-based orders and Wiza's credit plans. It's a fair option if you want file-based buying without the staleness gamble.

Which Should You Choose?#

Short version: pick Wiza if your prospecting starts in LinkedIn. Pick Exact Data if you need volume and company detail for non-email channels. Pick neither if what you really need is verified emails on demand.

Choose Wiza when your SDRs live in Sales Navigator. Your ideal customer is defined by title and company traits visible on a profile. You need contacts in the tens or low hundreds per week. The freshness advantage is real, and it cuts your bounce rate directly.

Choose Exact Data when you run direct mail or outbound calling. In those channels a physical address and phone matter more than an email. It also wins when you need consumer-side traits no B2B scraper has. Budget for independent verification on top of the purchase price. Treat it as a line item, not an optional extra.

Choose an API-first finder when you already know who you want to reach and just need the address. That covers most teams running account-based outbound against a defined target list. At typical volumes it's the cheapest of the three by a wide margin. Compare it against your current spend using the published Tomba pricing before you renew anything.

Get Verified Emails Without Buying a List#

If you've read this far, you probably have a target list and a stale-data problem. Skip the list broker. Skip the scrape. Point Tomba Email Finder at a name and a domain. You get a verified professional email back, with a confidence score and the sources behind it. There are 25 free searches a month, so you can test it against your own known-truth sample. Starter is $49/mo for real volume. Run the five-step evaluation above on Tomba the same way you'd run it on Exact Data or Wiza. That's the only comparison that reflects your data instead of someone's marketing page.
