9 Best FullCircl Alternatives for B2B Data and KYB in 2026

TL;DR

• FullCircl is a UK-first "customer lifecycle intelligence" platform. It bundles company data, credit and risk signals, KYB/AML checks, and sales triggers into one contract.
• It is strong on regulated onboarding. It is weak on self-serve access and contact-level data.
• There is no public price list. Buyers report annual, seat-and-volume contracts agreed with a salesperson. That rules it out for small teams and one-off projects.

Which FullCircl alternatives you need depends on the job:

• Risk and KYB: Creditsafe, Dun & Bradstreet, Encompass.
• Company intelligence and triggers: Cognism, Vainu, ZoomInfo.
• Contact data and email: Tomba, BookYourData, Apollo.

Most teams overpay because they buy one platform for three jobs. Splitting the bundle into a risk source plus a contact source is usually cheaper. It is also more accurate.

What is FullCircl, and who actually uses it?#

FullCircl came out of a 2021 merger. Artesian Solutions brought sales triggers and news monitoring. DueDil brought company graph data. The company later bought W2 Global Data to add KYC and AML screening. In 2025, nCino acquired the business. For the vendor's own framing, see fullcircl.com.

That history explains the shape of the product. FullCircl is not a prospecting tool that grew a compliance module. It is a compliance and onboarding tool that grew a prospecting module. Its core buyers are UK banks, insurers, brokers and lenders. They need to answer three questions about a limited company:

1. Is this business real and safe to onboard? Companies House filings, ownership structures, group hierarchies, adverse media, sanctions and PEP checks.
2. Is it financially healthy? Credit scores, late filings, county court judgments, director history.
3. Is now the right time to sell to it? Funding rounds, hiring spikes, news mentions and filing changes, used as trigger events.

If you use all three, FullCircl holds together well. If you use one, you are paying platform money for a point job. That is why people start shopping for FullCircl alternatives.

Why do teams look for FullCircl alternatives?#

Five reasons come up again and again on review sites like G2 and in buying calls. Here are the first three.

• No public pricing. Every conversation starts with a demo and a discovery call. There is no free tier and no card checkout. You cannot test coverage on your own list first.
• UK and Ireland gravity. The company graph is built on Companies House and Irish CRO filings. Coverage outside those markets thins out fast. If you sell to North American SaaS firms, you will feel the gap.
• Contact data is the weak leg. FullCircl tells you a company matters and names the directors. It is far less reliable at giving you a verified work email for the mid-level buyer you need.

The last two reasons are about the contract rather than the data.

• Annual commitments. Deals are seat-based and volume-tiered, renewed each year. That hurts if your headcount moves or your outbound program is seasonal.
• Ownership change. Any acquisition shifts roadmaps and pricing. Teams renewing in 2026 want to know what nCino ownership means for standalone customers.

None of this makes FullCircl a bad product. It makes it a specific product for a specific buyer. Check pricing and coverage claims with the vendor before you decide. The notes below reflect public information at the time of writing.

How do the top FullCircl alternatives compare?#

Here is the honest landscape of FullCircl alternatives. "Self-serve" means you can sign up and pull data without talking to a salesperson.

The table makes the core point. FullCircl competes with three different clusters at once. No single tool replaces the whole bundle. So the best FullCircl alternatives for you depend on the cluster you actually opened FullCircl for last month.

Which FullCircl alternatives fit KYB, onboarding, and risk?#

If compliance is why FullCircl sits in your stack, these are the serious swaps to test.

Creditsafe is the closest like-for-like on risk. It publishes credit scores and limits across a large multi-country database. It supports portfolio monitoring with alerts and has a mature API. It does not pretend to be a sales-trigger platform. That is a feature if you only wanted risk. UK coverage is excellent. Test the other countries you care about during a trial.

Dun & Bradstreet is the enterprise answer. The D-U-N-S number is still the standard global company identifier. You may need one record that lines up across 200+ countries and feeds Salesforce or SAP. If so, this is the default. It is also the priciest option and the slowest to set up. Do not buy D&B to run a 40-account outbound pilot.

Encompass attacks the hardest part of the job. It unwraps ownership structures to find ultimate beneficial owners automatically, across countries, with an audit trail. Is your compliance team clicking through five layers of holding companies by hand? Encompass fixes that specific pain better than FullCircl does.

Companies House directly. This one is worth saying out loud. The UK Companies House API is free and public. Say your only real need is to confirm a company number, check filings and list directors. You can build that in a sprint. Vendors add value through clean-up, monitoring, adverse media and reach beyond the UK. They add nothing to the base UK filings. Make sure you are paying for the first list, not the second.

Which FullCircl alternatives fit sales intelligence and triggers?#

Did you buy FullCircl for the Artesian half? News alerts, funding events and hiring signals routed to reps? Then the shortlist changes.

Cognism is the strongest UK and EU native rival for outbound. It leads on phone-verified mobile numbers. Its privacy setup is built for GDPR, including notified-contact rules across Europe. It is contact-first where FullCircl is company-first, so it pairs well with a risk vendor.

Vainu is the Nordic version of FullCircl's trigger engine. It holds deep company data in Finland, Sweden, Norway and Denmark. The CRM workflow is genuinely good. If your market is Northern Europe rather than the UK, Vainu often fits better.

ZoomInfo brings the largest contact database and the most developed intent data. It is also US-weighted and priced for teams that will use the whole platform. Stress-test two things in a trial: European coverage and European privacy compliance.

6sense and Demandbase belong here only if the real job is account-based intent and ad targeting. That is a different budget line, not a company-records tool.

What about contact-level data — emails and phones?#

Almost every FullCircl user describes this gap. You can spot the 300 accounts that just filed 40% revenue growth. Then you still have to work out who the CFO is and how to email them.

There are three ways to close it. The first is a dedicated finder.

1. Add a dedicated email finder. A tool built for one job beats a contact module bolted onto a compliance platform. That job is turning a name and a domain into a verified, deliverable inbox. Tomba runs a domain search and returns every discoverable address with a confidence score and a source. Pattern detection also lets you infer formats for people who are not in any database yet.

The second step is verification, and it is not optional.

2. Verify before you send, always. Company data ages by roughly 2–3% a month through job changes alone. Running your list through an email verifier is the cheapest way to protect your sender reputation. Catch-all domains are very common in UK financial services. They need a dedicated check, not a simple valid or invalid flag.

The third option only applies to one-off work.

3. Buy targeted lists for one-off campaigns. For a single event or a market test, a subscription is the wrong shape. BookYourData works well here: pay-as-you-go credits, filters by role and location, an accuracy guarantee on delivered records, and no annual deal. It solves a different problem than a platform does, and it solves it cleanly.

For ongoing programs, add an enrichment step to your pipeline. Manual list-building cannot keep up. Pull the account list from your risk or intelligence vendor. Push it through enrichment to attach people and emails. Then load it into your CRM. The Tomba API and the B2B database exist for that hand-off. Rate limits are published, not negotiated.

How much do FullCircl alternatives actually cost?#

Nobody in this category publishes a rate card, which makes budgeting hard. Here is the realistic shape of each model. It is based on public pricing and on patterns buyers report. Treat any non-public number as directional and confirm it with the vendor.

The pattern is clear. Anything sold as "customer lifecycle intelligence" comes with an enterprise contract. Anything sold as a tool comes with a published price. Does your finance team need a number this quarter rather than next? Then that split matters more than any feature comparison of FullCircl alternatives.

How do you choose the right FullCircl alternative?#

Run these six steps in order. They take about a week and save a year of regret.

1. Audit what you actually used. Pull 90 days of platform logs. If 80% of sessions were company lookups, you do not need a trigger platform.
2. Split the need into risk and revenue. They have different buyers, budgets and renewal dates. Buying them apart usually costs less and performs better.
3. Test coverage on your list, not their demo. Give each vendor the same 200 real accounts from your ICP. Measure match rate, field completeness and how stale the records are. Demo data is always curated.

The last three steps are the ones buyers skip.

4. Score contact accuracy on its own. A vendor can be 95% right about the company and 60% right about the person. Only the second number moves your reply rate.
5. Check the exit. Can you export your enriched records? Is there an API, or only a screen? What happens to alerts the day the contract lapses?
6. Price the whole stack, not one line. A $99/mo contact tool plus a mid-tier risk vendor often beats a single five-figure platform on cost and on results.

FAQ#

Is FullCircl only useful in the UK? Not only, but that is where it is strongest. The company graph is built on UK and Irish filings. International records exist and keep growing. Still, if your buyers are mostly North American, a US-first vendor will match more of your accounts.

What is the closest single replacement for FullCircl? There is no clean one. Most FullCircl alternatives cover one third of the bundle. Creditsafe is closest on risk and monitoring. Cognism is closest on UK and EU sales intelligence. Most teams that leave end up running two tools.

Do I need a KYB platform if I only do outbound sales? No. KYB, sanctions screening and UBO discovery are onboarding duties for regulated firms. If you do not onboard customers under AML rules, you are paying for compliance tooling you will never open.

Can I just use free Companies House data? For UK company identity, filings and directors, largely yes, via the free API. What you lose is clean-up, change monitoring, adverse media, international coverage and contact data. Build the free layer and buy the rest.

How do I get verified emails for the accounts I find? Take the domain and run a domain search. That returns every discoverable address plus the company's email pattern. Then verify each address before you send. Most company-intelligence platforms do not do that two-step flow well.

Where to start#

Is your FullCircl renewal coming up? Separate the two jobs before you sign anything. Keep or replace the risk layer with the vendor that fits your regulatory duties. That means Creditsafe, D&B or Encompass, depending on scale and geography. Then handle the revenue side with a tool that prices openly and gets you contacts you can actually email.

That second half is where Tomba's Email Finder fits. Feed it a company domain. You get every discoverable work email with a confidence score and the source behind it. Verification and catch-all handling are built in. The free tier gives you 25 searches a month, so you can test coverage on your own account list first. Starter is $49/mo when you are ready to scale. Try it on the 50 accounts you care about most this week. Then compare the match rate with whatever your current platform returns.
