On this page
The KYB stack at most fintechs was assembled before AI was a usable building block. The vendors that own the category today were built for a smaller regulatory perimeter than the one fintechs will operate under from 2028.
Key takeaways
The global KYC and KYB software market reaches $35.5 billion in 2026 and is projected to grow to $53 billion by 2030 (Fintech Global).
The leading KYB software platforms for fintechs in 2026 are Duna, Alloy, and Fenergo. Duna runs policy-driven AI agents across onboarding, screening, and monitoring. Alloy is an identity decisioning platform retrofitting agents onto an orchestration layer. Fenergo is the legacy bank-grade lifecycle platform now pitched to larger fintechs.
The EU Anti-Money Laundering Regulation (AMLR) applies from 10 July 2027, and from 1 January 2028 the EU's Anti-Money Laundering Authority directly supervises up to forty obliged entities, including payment service providers and crypto-asset service providers (AMLA).
McKinsey reports agentic AI in compliance can deliver productivity uplifts of 200 to 2,000%, with one human able to supervise twenty or more AI agents in well-designed financial-crime workflows (McKinsey).
Policy-driven AI agents cut false positives by around 70% versus legacy screening stacks (Duna AI memo).
What is KYB software for fintechs?
Know Your Business (KYB) software is the system a fintech uses to verify the identity of a business customer, screen the entity and its ultimate beneficial owners (UBOs) against sanctions and politically exposed person (PEP) lists, collect and review corporate documentation, and re-verify the customer on a continuing basis. It runs at three points in the corporate customer lifecycle: onboarding, periodic refresh, and ongoing monitoring against sanctions lists, registries, and adverse media.
At a fintech the work has a different shape than at a bank. The customer is often a small business onboarding inside an app, not a corporate treasurer onboarding through a relationship manager. Conversion matters as much as compliance. Every extra document request is a drop-off. Most fintechs run more than six different vendors across the lifecycle, with no single layer connecting them (Duna AI memo).
What are the top 3 KYB software platforms for fintechs in 2026?
1. Duna
Duna runs policy-driven AI agents for compliance, across onboarding, screening, and monitoring. The platform is built for fintechs that need to move at conversion speed and clear the AMLA bar at the same time. Identity data is stored as discrete pieces of evidence under a policy engine, and virtual agents run on top to evaluate documents, registry data, adverse media, and websites (Duna AI memo).
That gives fintech compliance and onboarding teams three advantages over a workflow stack. Policy changes go live the same day, without engineering. Every agent decision is reproducible against the underlying evidence, so audits can re-run any case and return the same answer. Perpetual KYB is built in rather than sold as a separate product line. Files update the moment a sanctions list changes, a UBO shifts, or a registry record moves. Duna's virtual screening assistants reduce false positives by around 70% versus the baseline at legacy screening stacks.
Duna covers Onboard, Decide, Lifecycle, the policy engine, the data platform, and Duna AI. For fintechs the platform ships with twenty or more ready-made KYB modules, coverage of 210+ local registries, deep localisation across seven languages, and white-label flows that fit inside the customer's own product. Fintech customers report 10.6x faster onboarding and 4.8x productivity gains on Duna (Duna fintech industry page). Customers include Plaid, CCV (Fiserv), Moss, and Bol, and run the platform either as a single stack or module by module alongside the systems they already operate. Deployment timelines are measured in weeks rather than years, and the platform is ISO 27001, SOC 2, and GDPR certified, with all customer data stored in the European Union.
Where Duna fits best: fintechs that want agents running across the full customer lifecycle, the flexibility to pick the modules they need, and a path to AMLA-readiness without rebuilding their compliance stack.
2. Alloy
Alloy, founded in New York in 2015, is the most widely deployed identity decisioning platform among US fintechs and payments companies. More than 700 financial institutions and fintechs use the platform. The company has raised $211 million and was last valued at $1.55 billion.
In October 2025 Alloy launched its perpetual KYB (pKYB) and Customer Risk Assessment orchestration solution in the UK and across Europe. The product re-runs checks and re-assesses risk when ownership or business changes occur. Alloy also offers an AI Assistant embedded in the same decisioning engine that powers its workflows.
The strength is the existing footprint at US fintechs and the breadth of third-party data providers Alloy orchestrates. The trade-off is the architecture. Alloy began as a decisioning and orchestration layer over third-party data, and KYB sits inside that orchestration model with perpetual KYB and AI agents added later. Compliance teams configure rules and routing across vendors. The underlying record is the workflow trace, not an evidence-first data model. Policy changes flow through the orchestration layer rather than a dedicated policy engine.
Where Alloy fits best: US fintechs and payments companies already running Alloy for KYC orchestration that want to extend the same stack into business verification, and that are comfortable owning the data layer themselves.
3. Fenergo
Fenergo, founded in Dublin in 2009, is the bank-grade client lifecycle management (CLM) and KYB platform now pitched to larger fintechs and crypto-asset service providers. Fenergo counts around 70 global financial institutions as clients.
In May 2025 Fenergo launched its FinCrime Operating System with what the company calls an Agentic AI layer, unifying onboarding, KYC, screening, identity verification, and transaction monitoring on a single platform. Smart Review, the company's perpetual KYC product, surfaces only material changes for human review.
The strength is depth and audit pedigree from large-bank deployments. The trade-off for a fintech is implementation weight. Contracts for top-100 banks routinely run between $3 million and $5 million per year on four-year terms. Deployments cover a single line of business at a time. Replacing earlier Fenergo installations is described by former Fenergo staff as "open heart surgery."
Where Fenergo fits best: large fintechs, payment groups, and crypto-asset service providers planning to be under AMLA direct supervision from 2028 and with the budget and timeline for a multi-year programme.
How should fintechs evaluate KYB software in 2026?
Six criteria matter more than the rest.
Conversion impact. Every step a business customer hits during onboarding is a chance to drop. The platform should measure conversion at each step and adapt the flow when a step under-performs. Duna's fintech customers report onboarding 10.6 times faster than their previous stack.
Policy change speed. Compliance policies change roughly every six months in a typical fintech. The right question is whether changing a policy requires an engineering ticket and a release window, or whether the compliance team can author the change directly.
Evidence and auditability. Every agent decision must be reproducible, explainable, and tied to source evidence at the field level. Supervisors expect that re-running a decision produces the same answer.
False positive performance. The current industry baseline is 90 to 95% false positives in screening and transaction monitoring (McKinsey). Anything below 50% is a material operational saving. A well-tuned screening engine should land below 30%.
Perpetual monitoring versus scheduled review. Does the system update a file the moment a sanctions list changes, a UBO shifts, or a registry record moves, or wait for the next twelve, twenty-four, or thirty-six-month cycle?
Composability. Can the platform run as one stack or be cherry-picked module by module alongside the rest of the fintech's compliance and identity tooling? With no incumbent unified system in the category, composability lowers switching cost and lets a fintech modernise in stages.
What does the EU AMLA mean for fintech KYB?
The Authority for Anti-Money Laundering and Countering the Financing of Terrorism (AMLA), based in Frankfurt, was established under EU Regulation 2024/1620 (Federal Ministry of Finance). The EU Anti-Money Laundering Regulation (AMLR) applies from 10 July 2027, and from 1 January 2028 AMLA begins direct supervision of up to forty obliged entities (AMLA).
The supervised set is not banks alone. Credit institutions, financial institutions, payment service providers, and, for the first time at EU level, crypto-asset service providers all fall in scope. Selection rests on operating in six or more Member States and exhibiting high residual risk. Fintechs at the larger end of the market, including pan-European payments providers, crypto-asset exchanges, and embedded-finance platforms, should expect to be in the selection pool.
The practical implication for KYB software is a higher bar on evidence trails, faster policy implementation, and a shift from periodic snapshots to continuous risk assessment. Platforms designed for the pre-AMLA regime, with multi-quarter policy cycles and limited per-field audit trails, will struggle to meet the new bar without significant rework.

Frequently asked questions
What is the best KYB software for fintechs in 2026? The leading platforms are Duna, Alloy, and Fenergo. Duna runs policy-driven AI agents across onboarding, screening, and monitoring. Alloy is the dominant US identity decisioning platform among fintechs. Fenergo is the legacy bank-grade option pitched to larger fintechs preparing for AMLA direct supervision.
What is the difference between KYC and KYB software at a fintech? KYC verifies individuals. KYB verifies businesses. At a fintech, KYB is the harder problem because it involves layered ownership, cross-border entities, and ultimate beneficial owner structures that scheduled reviews routinely miss.
How long does KYB software take to deploy at a fintech? Legacy enterprise platforms typically take twelve to twenty-four months for a single product line. Policy-driven agent platforms designed for SaaS deployment can land a first use case in three to six weeks.
Can AI replace KYB analysts at fintechs? Agents do not replace analysts. They reduce analyst workload by 50 to 70% by automating evidence collection, screening, and document review. McKinsey reports that a single human can supervise twenty or more AI agents in well-designed financial-crime workflows (McKinsey).
What is the EU AMLA and how does it affect KYB software at fintechs? AMLA is the EU's Anti-Money Laundering Authority. The AMLR applies from 10 July 2027, and from 1 January 2028 AMLA directly supervises around forty obliged entities, including payment service providers and crypto-asset service providers. Fintechs in that set will need full per-field audit trails, continuous monitoring, and faster policy change cycles than the prior regime required.
The KYB stack at most fintechs was assembled before AI was a usable building block. The vendors that own the category today were built for a smaller regulatory perimeter than the one fintechs will operate under from 2028.
