Exellius vs FullCircl: Different Tools, Different Jobs
You're comparing a fishing rod to a smoke detector. Exellius vs FullCircl isn't a real product showdown - one finds B2B emails and phone numbers for sales teams, the other is a RegTech platform for KYC/KYB/AML and customer due diligence used by banks, lenders, and other regulated businesses. Both touch company data, but they serve completely different buyers solving completely different problems. We've evaluated both, and the real question isn't which is better. It's which one you actually need.
30-Second Verdict
- Need B2B contact data - emails, phone numbers, lead lists for outbound? Exellius.
- Need KYC/KYB/AML compliance orchestration for customer onboarding at a regulated institution? FullCircl.
What Is FullCircl?
FullCircl is a RegTech platform born out of the 2021 merger of Artesian Solutions and DueDil. It helps regulated teams align customer acquisition with risk and compliance - running KYC, KYB, and AML checks across 160+ jurisdictions and processing 300 million checks per month. Its rules-based orchestration engine lets compliance teams drag-and-drop due diligence workflows, with results returned in under two seconds.
Notable modules include SmartOnboard (automated KYC/KYB), SmartAcquire (customer acquisition intelligence), and ProBanker (portfolio-level financial health views). G2 gives it a 4.5/5 from 243 reviews, and users praise the intuitive interface and timely alerts. The consistent complaint? Prospector lists lack telephone numbers - a dealbreaker if you're trying to use FullCircl for anything resembling outbound sales.
What Is Exellius?
Exellius is a B2B contact data platform covering 160M+ decision-makers. It bundles email finding, real-time and bulk email verification, phone lookup, and enrichment into one credit-based system - firmographics, technographics, and intent signals all included. On Datarade, it holds a 4.9/5 rating from 3 reviews, with users highlighting accurate data and a high email delivery rate. It also shows up in a r/b2b_sales thread alongside RocketReach, UpLead, and Kaspr as a phone number provider worth evaluating.
Pricing runs from free to $199/mo on a credit model, plus an Enterprise tier with custom pricing. The platform positions itself as a pay-for-what-you-use alternative to bloated enterprise contracts.

Exellius caps at 160M profiles. Prospeo covers 300M+ with 98% email accuracy, 125M+ verified mobiles, and a 7-day data refresh - not weeks. At ~$0.01 per email, you get enterprise-grade contact data without the enterprise contract.

Let's be honest: no other comparison page acknowledges that these are fundamentally different product categories. In our evaluation, the category difference becomes obvious within minutes of looking at either platform.
Pricing Breakdown
Exellius publishes everything on its pricing page: Free ($0/mo, 75 credits), Basic ($59/mo, 6,000 credits), Growth ($119/mo, 13,000 credits), and Professional ($199/mo, 25,000 credits). Unused credits roll over for 3 months. Worth noting that Datarade lists a slightly different pricing structure, so confirm current tiers directly on the Exellius site.

FullCircl is quote-based. The official FullCircl pricing URL we attempted returned a 404, so we're relying on third-party directories: roughly $125/user/month via SelectHub, or about £1,500/user/year via Capterra. Expect the real number in the mid-to-high four figures per user per year once check volumes and module access are factored in. You're committing to a sales conversation before you know if it's in budget - which is frustrating if you're just trying to scope costs for a budget proposal.
When to Use Which
SDR teams and outbound agencies building prospect lists and running cold email sequences should go with Exellius. You need emails and phone numbers, not compliance checks. FullCircl won't generate a single lead for your pipeline.

Compliance and risk officers at banks, lenders, or regulated fintechs need FullCircl. You need KYC/KYB orchestration, sanctions screening, and audit trails - Exellius doesn't touch any of that.
For fintech RevOps teams that need both compliance workflows AND outbound contact data, you're buying two tools. Period. These categories don't converge, and no single vendor covers both well.
Skip Both for Outbound Contact Data
If you landed on this comparison looking for the best way to get verified emails and direct dials, neither tool is the strongest option at scale. We've tested dozens of providers in this space, and Prospeo consistently outperforms on the metrics that actually matter for outbound: 300M+ professional profiles with 98% email accuracy, 125M+ verified mobile numbers, and a 7-day data refresh cycle while the industry average sits at six weeks. It integrates natively with Salesforce, HubSpot, Lemlist, Instantly, and Clay, and starts with a free tier. Teams using Prospeo book 26% more meetings than ZoomInfo users and 35% more than Apollo users - at roughly $0.01 per email.


If you're here comparing B2B contact data tools, skip the guesswork. Teams using Prospeo book 26% more meetings than ZoomInfo users and 35% more than Apollo users - with emails that actually land (98% accuracy, bounce rates under 4%).
