KYB providers verify business customers and their owners. Compare registry access, UBO depth and coverage in 2026, after the US beneficial ownership shift.
Table of contents
- We read every vendor-authored ranking that surfaces for this query on 31 August 2026. Of the eight that carry a ranked list, seven include the publisher, and six of those seven place the publisher first. One discloses that it does so.
- Every published comparison of KYB providers is written by a KYB vendor. Read the coverage numbers as marketing claims made by the vendor about itself, because that is what they are.
- The ground moved in 2026. FinCEN's final rule at 91 FR 52508, effective 14 August 2026, adopted as final the March 2025 interim rule that removed the domestic reporting company category. FinCEN puts the remaining reporting population at approximately 28,000 companies, and estimates that approximately 27.5 million have been relieved of reporting obligations since that interim rule.
- That removes a government-held ownership source American KYB providers were expected to lean on, so ownership now has to be reconstructed from filings, documents and human review.
- The European Union is moving the other way. Regulation (EU) 2024/1624 applies from 10 July 2027 and sets the beneficial ownership test at 25 percent or more, with lower thresholds permitted for higher-risk cases.
- Coverage counts are the least useful way to choose. A provider with 220 country coverage and a provider with 50 US states can both be correct answers, depending on which side of that divergence you onboard.
- The question nobody in the category answers on their pricing page: after you have verified a director's passport, who is holding the image, and for how long.
KYB providers are vendors that verify a business customer's legal existence, ownership and risk profile before and during a commercial relationship. They pull company records from corporate registries, resolve the ultimate beneficial owners behind the entity, screen those people against sanctions and adverse media, and monitor the file for change.
TL;DR
Pick your KYB provider by jurisdiction and evidence quality, not by the size of the coverage number on the homepage. If you onboard American businesses, the useful test is depth of Secretary of State and IRS data, because the federal beneficial ownership register no longer covers domestic entities. If you onboard European businesses, the useful test is readiness for the 2027 AML Regulation and access to primary registry documents rather than resold databases. If you onboard both, expect to run two sources and a review team over the top. And ask every vendor on your shortlist where the verified documents are stored once the check has passed.
This article is for compliance, risk and onboarding leads running a KYB vendor selection or a migration, at companies onboarding business customers under an anti-money laundering obligation. It covers provider selection, the regulatory ground underneath it, and an evaluation method. It does not cover pricing negotiation, implementation engineering, or the separate question of individual KYC vendor choice, which our KYC software page handles instead.
What do KYB providers actually do?
A KYB provider answers four questions about a business customer, in order. Does this company exist as a legal entity, and is it in good standing. Who owns and controls it, down to the natural persons. Are any of those people or the company itself on a sanctions list, a politically exposed persons list, or in adverse media. And has any of that changed since you last looked.
Only the first question is mostly solved. Company existence is a registry lookup, and the registries are public in most developed markets. The other three are where KYB providers differ, and where the price differences come from.
Ownership resolution is the hard part. A company is owned by two holding companies, one of which is owned by a trust in another jurisdiction, which is controlled by three natural persons. Reconstructing that chain is not a lookup, it is a recursive traversal across registries that use different identifiers, different languages and different filing standards. Most KYB providers will resolve simple structures automatically and hand you the complicated ones to sort out by hand.
For the definitional groundwork, our KYB glossary entry covers the term itself, and KYC vs KYB covers why business onboarding is a different problem from individual onboarding rather than a bigger version of it.
What changed for KYB providers in 2026?
For most of the last three years the working assumption in the category was that the United States was about to get a beneficial ownership register, and that KYB providers would query it the way they query Companies House in the United Kingdom.
That assumption is now dead. FinCEN's final rule revising the beneficial ownership information reporting requirement, published at 91 FR 52508 and effective 14 August 2026, adopted as final the interim final rule of 26 March 2025. The domestic reporting company category, previously defined at 31 CFR 1010.380(c)(1)(i) as an entity created by a filing with a secretary of state, is gone. Foreign entities registered to do business in the United States still report, and the final rule exempts US person beneficial owners and US person company applicants from being reported at all. FinCEN's own analysis puts the remaining non-exempt reporting population at approximately 28,000 companies, and estimates that approximately 27.5 million have been relieved of reporting obligations since that interim rule.
The practical consequence for anyone shortlisting KYB providers is specific. There is no authoritative federal source of truth for who owns an American company. Ownership has to be assembled from state filings, corporate documents, self-attestation by the customer, and analyst judgement about whether the story hangs together. Vendors whose ownership product was built on the expectation of a register are now doing the same reconstruction work as everyone else, and you should ask them directly how they do it rather than accepting "UBO coverage" as a checkbox.
This is also why the compliance obligation did not move. FinCEN's customer due diligence rule at 31 CFR 1010.230 still requires covered financial institutions to identify and verify beneficial owners of legal entity customers at account opening. The reporting duty on companies changed. The verification duty on you did not.
Who are the main KYB providers?
The figures below are each vendor's own published claims about itself, taken from its own site and dated to this writing. They are not independently audited, and they are not comparable line by line, because vendors count different things. Treat the table as a map of positioning, not a scoreboard.
| Provider | Positioning | Published figures (vendor's own claims) | Strongest for |
|---|---|---|---|
| Middesk | US business verification from primary government sources | 7M businesses verified annually, 400+ government and authoritative sources, 10 percent of US businesses verified within 90 days of forming | US-only onboarding where Secretary of State and IRS depth is the whole job |
| Sumsub | All-in-one KYC and KYB on one platform | 220+ countries, 600M+ commercial records, 30K+ data sources, 15 second average automated business check, manual document review across 140+ countries | Teams that want individual and business verification in a single contract |
| Trulioo | Global normalisation behind one API | 195 countries, 700M verifiable business entities, 450+ data sources, 500 business registration number formats, 150 normalised data fields | Cross-border onboarding where output consistency matters more than depth |
| Moody's | Entity and ownership datasets with primary source register access | 635M+ entities, 30M+ curated risk profiles including 7M+ PEPs, 200+ countries and jurisdictions | Complex corporate structures and audit-grade documentary evidence |
| GBG | Enterprise onboarding across ownership registries | 190+ countries, 600m+ company records, 200 beneficial ownership registries | Large institutions with existing enterprise procurement |
| Zyphe | Registry-native KYB with an operated review layer and no retained document store | 240+ registries, identity verification across 190+ countries, integration in as little as 15 minutes | European-first onboarding where stored document liability is a board-level concern |
Two honest observations about that table.
First, the coverage numbers are not measuring the same thing. Trulioo's 700M verifiable business entities is a database size. Middesk's 400+ sources is a connector count. Sumsub's 15 seconds is a latency figure for the automated path only, which tells you nothing about the manual path where the hard cases go. A comparison that ranks KYB providers by stacking these numbers against each other is comparing a distance to a weight.
Second, the category is dominated by vendor-authored listicles. Search "KYB providers" and the first page is almost entirely blog posts published by companies that sell KYB, each of which happens to rank itself favourably. This post is also published by a vendor. The difference we can offer is disclosure of the method and the sources, so you can check the claims yourself.
What happens when a vendor ranks its own category?
Because every comparison in this category is vendor-authored, we tested how much that matters instead of asserting it.
Method. On 31 August 2026 we ran the query "kyb providers", took every vendor-authored result returned, retrieved each page, and recorded three things: whether the page carries a ranked list of providers, whether the publishing vendor appears in its own list, and at what position. One page returned HTTP 403 to repeated requests and is excluded. One page ranks for the query under the title "The 7 Best KYB Software Providers of 2026" but is the publisher's own product page with no ranking on it, so it carries no list to record. That leaves eight ranked lists, seven of which include the publisher.
| Publisher | Vendors listed | Publisher's own position |
|---|---|---|
| AiPrise | 8 | 1 |
| Binderr | 5 | 1 |
| Compliancely | 5 | 1 |
| GBG | 9 | 1 |
| Shufti | 9 | 1, disclosed on the page |
| Signzy | 10 | 1 |
| Kyckr | 7 | 3 |
| Didit | 5 | not ranked, publisher framed as the evaluator |
The finding: of the seven rankings that include their publisher, six put the publisher in first place. The single exception is Kyckr, which places itself third behind Moody's and Dun and Bradstreet. Shufti is the only publisher that states the arrangement openly, telling readers it lists itself first and orders the remaining eight alphabetically, which is a more honest treatment than the silent version.
Two limits on this. The sample is small, it reflects one query on one day from one location, and search results vary. And we are not a neutral party running it, which is the same objection we are raising about everyone else. What the exercise does establish is that a ranked position in this category carries close to zero information, because the ranking author is almost always the winner. Zyphe does not appear in any of the nine pages we could retrieve, which is part of why we wrote this one.
The practical use is simple. When you read any KYB provider ranking, including this page, find the publisher first. If the publisher is at the top of its own list, treat the ordering as marketing and read only the underlying facts.
How should you choose between KYB providers?
Start from your own onboarding mix rather than from the shortlist. Three questions decide most of it, and we call them the JDC test: Jurisdiction, Depth, Custody. Answer all three before you open a feature matrix, because a coverage count cannot settle any of them.
Which jurisdictions are more than 5 percent of your volume? Everything below that threshold can be handled by exception, usually by a human. A provider that is excellent in 40 countries you do not sell into is not excellent for you. Pull last quarter's applications, sort by country of incorporation, and take the top decile. That is your real coverage requirement.
How deep do your ownership chains go? If your customers are mostly single-layer operating companies with two named directors, ownership resolution is close to free and you should optimise for speed and price. If you onboard holding structures, funds, or anything with a trust in it, ownership is the entire cost of the relationship and you should optimise for documentary evidence and analyst support.
What happens to the documents after the check passes? This is the question that separates KYB providers most sharply and appears on the fewest comparison pages. A director's passport image, once collected, becomes a liability that sits on someone's infrastructure for as long as your retention policy runs. Ask each vendor where that image lives, who can decrypt it, and what your exposure looks like if that vendor is breached. Then ask for it in the contract.

Our guide to KYB requirements sets out the obligations you are buying against, and KYB onboarding covers the flow design once the vendor decision is made.
What does the EU AML Regulation require?
Regulation (EU) 2024/1624, the AML Regulation, applies from 10 July 2027 and harmonises beneficial ownership across the Union. The threshold test is ownership or control of 25 percent or more, with member states and obliged entities able to apply lower thresholds where risk warrants it.
For provider selection, three implications matter.
The first is that a single European threshold removes an excuse. Until now a vendor could point at national variation to explain inconsistent ownership output across the bloc. From July 2027 the test is the same in every member state, and inconsistency becomes a product deficiency rather than a regulatory artefact.
The second is timing. Twenty-two months is one procurement cycle and one integration. If you are choosing among KYB providers this quarter, you are choosing the vendor that will carry you into the AML Regulation, so ask for their roadmap commitment in writing rather than a marketing statement about being ready.
The third is that Europe is now the jurisdiction with the better ownership data, which reverses the position most vendor roadmaps were built on. If your growth plan is European, weight registry depth in the Union heavily, and treat the American coverage story as the secondary requirement it has become.

Where does Zyphe fit?
We are one of the KYB providers in the table, so read this section with that in mind. Zyphe was ranked in the Chartis Research FCC50 2026.
Zyphe connects to 240+ corporate registries, resolves the ownership tree down to the natural persons, and then verifies each of those people using government identity documents from 190+ countries. That part of the workflow is not unusual, and several vendors above do it competently.
The structural difference is what happens next. Verified documents are not retained in a central store that we control. Records are split into encrypted fragments held across independent nodes, and the customer holds the key, which means there is no single pile of director passports to lose. For a compliance team whose board has started asking about vendor breach exposure, that changes the risk conversation from "how good is their security" to "what is actually there to take".
The second difference is the review layer. Alerts and ambiguous ownership chains are worked by analysts as part of the service rather than handed back to your team as a queue, which is the model described on our KYB software page and in KYB verification. Sanctions and adverse media on the resolved owners run through sanctions screening, and UBO screening carries the ownership side.
Where we would not recommend ourselves: if your onboarding is 95 percent domestic American small business and your board has no particular view on stored document liability, a US-native provider with deep Secretary of State pipes will serve you better and probably cost less. That is a real answer, and any vendor that cannot give you one is selling rather than advising.
How should you run the evaluation?
Do not run a feature comparison. Run the vendors against your own failed cases.
Take 100 real applications from the last quarter, weighted the way your book is actually weighted, and include the twenty that gave your team the most trouble. Send the same set to each shortlisted provider. Then measure four things: how many resolved automatically, how many resolved correctly when you check the ownership by hand, how long the exceptions took, and how much of the exception work landed back on your team.
That exercise takes about two weeks and settles arguments that a matrix cannot. It also surfaces the failure mode that matters most, which is a provider that returns a confident answer that is wrong. A vendor with an 80 percent automation rate and honest uncertainty flags is worth more than one at 95 percent that quietly guesses, because the second one moves risk onto you without telling you.
Price the exceptions, not the API calls. Most teams discover that the automated path costs very little and the manual path costs everything, so the vendor that handles exceptions as part of the service is often cheaper in total than the one with the lower per-check headline.
When is a single provider the wrong answer?
Sometimes it is, and no vendor will tell you that.
If you onboard meaningfully in both the United States and Europe, the divergence described above means no single vendor is currently best at both. The honest architecture is a primary provider for your dominant market and a secondary source for the other, with a routing rule in between. That is more integration work and a second contract, and it is still the correct answer for a book split evenly across the Atlantic.
Equally, if your volume is under a few hundred checks a month, the entire vendor selection exercise may be premature. A registry API and a competent analyst will outperform a badly implemented platform, and you can revisit KYB providers when the volume justifies the integration. The cost of choosing early and wrongly is a migration, and migrations in this category are painful because the verified records rarely move cleanly.
The bottom line
The useful way to compare KYB providers in 2026 is not by coverage count. It is by asking which side of the transatlantic ownership divergence you are onboarding on, how deep your ownership chains actually go, and where the verified documents end up once the check has passed. The first two questions determine which vendors can do the job. The third determines what you are carrying on your own risk register afterwards, and it is the one most comparison pages, including most published by KYB providers, quietly leave out.
If you want to run that test against us, the fastest route is a parallel run on your own historic cases. Book a demo and bring your twenty worst files.
