FullCircl vs Wiza (2026): Which B2B Data Tool Wins?

TL;DR — FullCircl vs Wiza in 30 seconds

• FullCircl vs Wiza is not a real head-to-head. FullCircl is a company-intelligence and onboarding platform for UK and EU regulated industries: banking, insurance, and B2B financial services. Wiza is a LinkedIn-first contact exporter for SDRs.
• Pick FullCircl if you need Companies House data, KYB/AML checks, credit signals, and account alerts inside Salesforce or Dynamics.
• Pick Wiza if your prospecting starts in LinkedIn Sales Navigator. It turns a saved search into verified work emails and phone numbers in minutes.

The rest of the trade-off comes down to price:

• Pricing works differently. Wiza publishes credit-based plans that start near $83 per month on annual billing. FullCircl quotes annual enterprise contracts and does not publish rates.
• If your real problem is email coverage at a fair price, neither tool is the cheapest route. A dedicated email finder with a real API and a $49/mo entry plan does that job without a seat-based contract.

Why does anyone compare FullCircl vs Wiza?#

Because both show up in the same search for "B2B data tool." The category label hides how different they are.

FullCircl (formerly Artesian Solutions, merged with DueDil) is a customer lifecycle intelligence platform. It pulls together company registry data, financial filings, credit indicators, news signals, and regulatory checks. Then it pushes all of that into your CRM. A relationship manager at a bank can see which of their 400 accounts just filed a director change or crossed a credit limit. IRIS Software Group acquired the company in 2024. The positioning is clear on fullcircl.com: onboarding, KYB, and regulated-market compliance come first, not prospecting volume.

Wiza sits at the other end of the funnel. It is a Chrome extension plus a web app. It turns a LinkedIn or Sales Navigator search into a CSV of names, titles, work emails, and mobile numbers. Its own site (wiza.co) leads with "export LinkedIn searches." That is the whole pitch, and it works well.

So the honest way to frame FullCircl vs Wiza is not "which one is better." Ask this instead: are you buying account intelligence or contact data? The two budgets usually sit with different people.

Wait — that's the meme slot:

What does FullCircl actually do?#

Start the FullCircl vs Wiza comparison with the bigger platform. FullCircl's product family covers three jobs:

1. Company intelligence — firmographics, corporate structures, ownership trees, financials, and filings for UK and international entities. Most of it comes from official registries.
2. Onboarding and KYB/AML — identity checks, sanctions and PEP screening, and business verification workflows. This part grew after the DueDil merger.
3. Account monitoring and alerts — "tell me when something changes at this company" signals, delivered into Salesforce, MS Dynamics, or an API.

Who it fits: a UK commercial bank, an insurance broker, a fintech with regulated onboarding, a B2B lender. These are teams where a missed compliance step costs more than a missed meeting.

Who it does not fit: a five-person SaaS startup running cold email into the US mid-market. You would pay for compliance tooling you never touch. Contact-level email coverage is also not the product's strength.

What does Wiza actually do?#

The other half of FullCircl vs Wiza is much simpler. Wiza's core loop is short:

1. Run a search in LinkedIn Sales Navigator, a regular LinkedIn search, or a list of profile URLs.
2. Hit the Wiza extension.
3. Wiza reads the profiles and adds a work email to each one. Higher plans add a mobile number.
4. Export a CSV, or push the list to HubSpot, Salesforce, Outreach, Salesloft, or Pipedrive.

SDRs like it because it inherits LinkedIn's filters. Those filters are still the best B2B segmentation on the market: headcount growth, job change recency, function, seniority, and posted-content signals. No static database matches them.

The trade-offs are just as clear. You depend on a LinkedIn account in good standing. Scrape volume has practical ceilings. Wiza also charges separately for email credits and phone credits. A list that looks cheap on the email line gets expensive once you want dials. That is why people start looking for a Wiza alternative as volume climbs.

How do FullCircl and Wiza compare head to head?#

Read the table as three columns of different jobs, not a scoreboard. Only one row makes all three collide: "get me a working email for this person."

Which one has better data quality?#

It depends on which record you ask about.

For company records, FullCircl wins outright. Registry-sourced data is authoritative in a way that scraped or crowd-sourced data never is. Do you need a UK company's registered directors, filing history, or SIC codes with audit-grade confidence? That is FullCircl's home turf. Wiza has no equivalent.

For person-level contact data, Wiza is stronger — with one caveat. LinkedIn titles and companies are usually current, because people update their own profiles. The email is different. It is guessed and then verified after the fact, not read off the profile. So the question becomes simple: how good is the email-finding engine behind the scrape?

That is where FullCircl vs Wiza gets interesting, because email finding is its own discipline. Coverage swings a lot by region, company size, and whether the domain is catch-all. A tool that reports 90% "found" but ships accept-all addresses has solved nothing. It just moved the risk to your bounce rate.

Practical rule: verify at the end of the pipeline, not the start. Run exports through a catch-all verifier before they touch a sending domain. A 4% bounce rate on a new domain can cost you inbox placement for a quarter. Google and Yahoo wrote that into their bulk-sender rules in 2024. Their published requirements set a hard 0.3% spam-complaint ceiling on senders.

What do FullCircl and Wiza cost in 2026?#

Here is the FullCircl vs Wiza pricing picture. One caveat: FullCircl does not publish rates.

Two things to notice.

One: Wiza's headline prices assume annual billing. Month-to-month costs meaningfully more. That is a standard SaaS pattern, but it catches teams that budget off the marketing page. Check the current numbers on Wiza's pricing page before you commit, because credit tiers move.

Two: FullCircl's cost is more than licence fees. Regulated-market platforms add implementation, CRM integration work, and often a minimum seat count. That is fair if you are a bank. It is absurd if you are an agency booking demos.

When should you use neither?#

Three common cases make FullCircl vs Wiza the wrong question entirely:

• You already have a target account list and just need emails. Skip account monitoring and LinkedIn scraping. Use a domain search that returns every public email pattern at a company, then verify. That is a $49/mo problem, not a $10k/year one.
• You are building this into a product or internal tool. Wiza's workflow runs through an extension with a human in the loop. If your pipeline is automated, you want a clean REST endpoint you can call from a job. Check whether the API is a first-class product or an afterthought.
• You work outside LinkedIn-dense markets. LinkedIn use is thin in Japan, much of the Middle East, and parts of Southern Europe. A LinkedIn-first tool inherits that gap. Domain-driven finding does not care whether a person has a profile.

One more honest note on the landscape. Do you need pre-built, human-verified lists with published counts and no scraping dependency? BookYourData is a solid option in that lane. It solves list-buying, which is a different purchase from either FullCircl or Wiza.

How do you actually choose?#

Work through these in order. The first "yes" is your answer.

1. Do you have a regulatory obligation — KYB, AML, sanctions screening — tied to onboarding customers? → FullCircl. Nothing here replaces that, and stitching it together from prospecting tools is a bad idea.
2. Do your reps build lists in Sales Navigator, and does your budget cover per-seat contact credits? → Wiza. The LinkedIn filter quality is real value.
3. Do you already know which companies you want, and only need who to email? → A dedicated email finder. Feed it domains, get back verified addresses, skip the platform tax.

If none of those three land, keep going.

4. Are you enriching an existing CRM rather than sourcing net-new? → Data enrichment against records you already own is cheaper than re-sourcing them, and it creates no duplicate contacts.
5. Is this going into automation? → Pick API-first tooling. Read the docs before the demo; docs do not oversell.
6. Is your bounce rate above 3%? → Fix verification first. New data will not rescue a burned sending domain.

What's the verdict?#

In FullCircl vs Wiza, each tool wins its own category and loses the other's. FullCircl is the right call for UK and EU regulated teams that need authoritative company data and compliance workflows inside the CRM. It is a serious platform sold to serious buyers, and the annual contract reflects that. Wiza is the right call for SDR teams whose prospecting habits live in Sales Navigator and who want exports without a data-engineering project.

Neither is right if your real bottleneck is email coverage and accuracy at a price that scales linearly. That is a narrower problem, and narrow problems suit narrow tools. Paying platform rates for what amounts to an email lookup is the most common overspend in this category.

Before you sign anything, run the same 100-contact test list through each candidate. Measure match rate, bounce rate after verification, and time to first export. Vendor accuracy numbers are marketing; your list is data. Peer reviews on G2 help surface support and billing complaints that never come up in a demo. They still cannot tell you how a tool performs on your ICP.

Ready to test coverage on your own list?#

If your FullCircl vs Wiza shortlist came down to "I just need accurate work emails, without an annual contract," start with the Tomba Email Finder. The free tier gives you 25 searches a month with no card. Benchmark the match rate against a FullCircl or Wiza export before you commit a budget line. Paid plans start at $49/mo, and every result runs through the same verification stack. Full Tomba pricing is public, and there is a documented API when you are ready to automate.
