Most fintech startups need two layers: identity verification at onboarding and AML screening plus transaction monitoring after it. Sumsub and Persona are the easiest places to start because both publish self-serve prices (Sumsub from $1.35 per check with a $149 monthly minimum, Persona Essential from $250 a month). Alloy is the pick once you are juggling several data vendors and need one decision layer, which is why banks and sponsor-bank fintechs use it. ComplyAdvantage is the specialist for sanctions, PEP and adverse-media screening from $99 a month. Unit21 and Sardine fit teams whose real problem is transaction monitoring and fraud at volume. Add Middesk if you onboard US businesses.
1. Best decision layer for banks and BaaS fintechs
Alloy
AI-powered identity, fraud and compliance risk management for banks, credit unions and fintechs across the customer lifecycle.
Alloy does not try to own every check. It orchestrates more than 250 identity data integrations and 300 partners, so you can run a document check from one vendor, a database check from another and a sanctions screen from a third, then apply one policy to the results. More than 900 banks, credit unions and fintechs use it. That design matters most for fintechs that sit on a sponsor bank, because the bank will want to see your onboarding rules and the evidence behind every decision. Pricing is quote-only; Software Advice lists it from $25,000 a year. Pick Alloy when you have more than one product, more than one data vendor, or a bank partner asking hard questions.
Pricing: Alloy does not publish standard plan prices; sales discussions determine the package and data usage. Software Advice lists Alloy from $25,000 per year, but this is a third-party benchmark rather than an official price sheet. Actual cost can vary with applicant and account volume, jurisdictions, selected partners, monitoring needs and modules.
Connects identity, fraud and compliance workflows instead of forcing teams to operate separate decisioning systems.
Supports both consumer and business onboarding with KYC, KYB, AML and fraud signals.
Extends risk controls beyond account opening through perpetual KYC, KYB and event monitoring.
Pricing is quote-based, so buyers cannot estimate a standard subscription from an official rate card.
The platform is built for regulated financial services and may be excessive for organizations needing only basic identity checks.
Automated decisions still require policy configuration, governance and analyst handling for unresolved or high-risk cases.
Configurable identity verification and KYC/KYB infrastructure for onboarding, fraud prevention, and compliance.
Persona builds verification from modules (government ID, selfie, database lookups, business verification, age checks) that you arrange into flows without much engineering. The Essential plan starts at $250 a month on a 12-month contract, and Vendr reports a $30,000 median annual contract across 59 purchases. It raised a $200 million Series D at a $2 billion valuation in April 2025. Persona is strongest on the identity side. It does screening and case review, but if you need full transaction monitoring you will pair it with Unit21, Sardine or a core banking provider's tooling.
Pricing: Essential starts at $250/month with a minimum 12-month contract. Growth and Enterprise pricing is custom or volume-based. Vendr reports a $30,000 median annual buyer price from 59 purchases and describes consumption-based pricing tied to verification volume.
Combines verification, workflows, fraud signals, graph analysis, and case review in one platform.
Supports government-ID verification in more than 200 countries and territories.
Publishes a $250/month Essential entry point rather than requiring every buyer to request a quote.
Growth and Enterprise pricing is custom, making total cost difficult to estimate from the public plan page.
Advanced checks, Graph, guided implementation, and bespoke programs are plan-dependent.
Consumption costs vary by verification type, volume, contract commitment, and workflow requirements.
Sumsub covers KYC, KYB, AML screening, transaction monitoring, fraud and the crypto Travel Rule in one product, and it is one of the few vendors that publishes prices: $1.35 per verification on the Basic plan with a $149 monthly minimum, or $1.85 with a $299 minimum on the Compliance plan, which adds AML screening. It serves more than 4,000 clients and verifies more than 2 million people a day by its own count. That makes it the default for crypto exchanges, neobanks and marketplaces that onboard users in many countries from day one. Expect per-check costs to vary with country tier and optional checks.
Pricing: Basic starts at $1.35 per verification with a $149 monthly minimum; Compliance starts at $1.85 with a $299 minimum. Custom pricing applies to larger volumes and the full platform. AWS Marketplace lists 60,000 annual checks at $120,000 for identity documents, $50,000 for liveness and face match, and $60,000 for AML screening.
Combines identity, business, AML, transaction, Travel Rule, and fraud controls in one platform.
Public self-service pricing and a 14-day trial support initial evaluation.
Supports 14,000+ identity documents from 220+ countries and territories.
The lowest advertised price carries a $149 monthly commitment.
Full-platform and higher-volume deployments require custom commercial discussions.
Optional checks, country tiers, and additional services can change per-applicant costs.
Socure built its reputation on US identity data and fraud scoring, and it now runs decisioning through its RiskOS platform for more than 6,000 customers. Its Launch tier is unusual for an enterprise vendor: no contract, a $1,000 monthly credit allowance, then document verification from $0.80 per evaluation and KYC plus fraud bundles at $1.00. Vendr's median annual contract is $17,500. Choose Socure when your users are mostly in the US and your goal is higher approval rates for thin-file customers without letting synthetic identities through.
Pricing: Socure Launch requires no contract or sales call and uses usage-based pricing after its $1,000 monthly credit allowance. Published Launch rates start at $0.80 per document-verification evaluation, with bundles ranging from $0.90 to $1.30 per evaluation. Vendr reports a $17,500 annual median buyer price and an observed range of $3,625–$205,800. AWS Marketplace lists SocureGov RiskOS at $250,000 for 12 months and 125,000 transactions; this is a marketplace benchmark, not a universal minimum plan.
Combines identity, document, fraud, watchlist and age workflows in one decisioning platform.
Launch provides a low-friction entry point with $1,000 in monthly credits.
ComplyAdvantage started as a risk data company and still competes on the data: sanctions lists, politically exposed persons and adverse media, refreshed continuously, with ongoing monitoring of customers you have already onboarded. Starter Essentials costs $99 a month on annual billing for up to 100 monitored entities, which is the cheapest legitimate way for a small fintech to show its bank partner a working screening program. Enterprise contracts are larger; Vendr's median is $52,900. False-positive review still needs a human, so budget analyst time alongside the subscription.
Pricing: Starter Essentials starts at $99 per month with annual billing for up to 100 monitored entities, while monthly billing for that allowance is $119. Agentic Starter begins at $149 per month with annual billing, and Enterprise is quote-based. AWS Marketplace benchmarks include $30,000 per year for 30,000 payment-screening transactions and $65,000 per year for 50,000 sanctions, PEP, and adverse-media screening units; Vendr reports a $52,900 median annual buyer contract.
Combines sanctions, PEP, adverse-media, customer, company, payment, and transaction screening in one platform.
Sardine combines device and behavioral signals with KYC, transaction monitoring, sanctions screening and case management, so the fraud team and the compliance team work from the same alerts. That is useful in payments and instant transfers, where account takeover and money mule activity look similar at first. It raised a $70 million Series C in February 2025. Sardine publishes no prices; Vendr's median buyer contract is about $95,000 a year with a minimum monthly commit and overages, so it suits companies with meaningful volume rather than pre-launch startups.
Pricing: Sardine does not publish list prices or a public tier table. Vendr reports a median buyer contract of $95,333 per year and a $15,000–$254,480 range; its buyer note describes a minimum monthly commit, platform and support fees, consumption charges, and monthly overages. These are third-party benchmarks, not Sardine's published rates.
Combines fraud, identity, device intelligence, and AML operations in one platform.
Supports web and mobile SDKs plus REST APIs for real-time event processing.
Configurable rules can route decisions to approval, decline, or manual review.
Pricing is custom and Sardine does not publish a self-serve plan or rate card.
The reported minimum-commit and overage model can make spend harder to forecast.
A broad financial-crime suite may exceed the needs of simple, low-risk ecommerce use cases.
Unit21 is where compliance teams write and test their own monitoring rules, investigate alerts and file SARs and CTRs, without waiting on engineers. Green Dot, Intuit and MoonPay are listed customers. The reason teams pick it over a bundled tool is control: you can backtest a rule on historical data before turning it on, which helps when an examiner asks why a threshold is set where it is. Vendr data shows contracts from roughly $33,000 to $740,000 a year, so it is a Series A and later purchase.
Pricing: Unit21 publishes no rate card, free plan, or self-serve checkout. Vendr buyer-transaction data reports contracts from approximately $33,000 to $740,000 annually, with an average near $160,000. Actual pricing depends on transaction volume, modules, analyst scope, integrations, and implementation requirements.
No-code configuration lets compliance teams create, test, and deploy rules and workflows.
The platform combines monitoring, investigations, case management, and filings rather than requiring separate workbenches.
Native and connected data sources cover core banking, identity, crypto analytics, warehouses, and CRM systems.
Pricing is not published and requires an enterprise sales process.
Implementation and data integration can require substantial customer-specific work.
Public materials do not provide independent recall, false-negative, or model-validation metrics.
If your customers are US businesses, Middesk checks Secretary of State filings, IRS name and EIN matches, addresses, people and watchlists from more than 400 government sources in all 50 states. It verifies about 150,000 companies a week for more than 600 customers. Vendr reports a $14,375 median annual contract and per-verification benchmarks of $2 to $5. Middesk is US-focused; for international KYB, Sumsub, Trulioo or Persona cover more countries.
Pricing: Middesk does not publish standard plan pricing or a self-serve purchase path. Vendr reports observed annual contracts of $10,000–$206,196, with a $14,375 median annual buyer spend. Vendr also reports core verification benchmarks of $2–$5 per verification at 1,000–5,000 monthly requests and low-volume annual minimums commonly between $10,000 and $30,000. These are buyer benchmarks, not Middesk list prices.
Combines KYB, screening, underwriting, registration, and monitoring in one U.S.-focused platform.
Connects to more than 400 government and authoritative data sources.
Supports dashboard workflows alongside REST API and MCP implementations.
Pricing is quote-based, usage-based, and not publicly itemized by plan.
There is no publicly documented free trial or self-serve purchase option.
International coverage is less central than U.S. business verification.
Regulators and sponsor banks do not ask whether you bought a KYC tool. They ask whether you have a program: written policies, a risk assessment, someone accountable, independent testing and controls that work. Software covers the controls. It helps to split them into four jobs, because vendors are strong at different ones.
Identity verification (KYC). Confirm that a person is real and is who they say they are. In the US the floor is the customer identification program rule, which requires name, date of birth, address and an identification number for each customer, plus a way to verify them. Vendors do this with document scans, selfies and liveness checks, and database lookups.
Business verification (KYB). For business customers, confirm the entity exists, who owns and controls it, and whether any of those people are sanctioned. The beneficial ownership threshold under the US customer due diligence rule is 25 percent.
Screening. Check customers against sanctions lists such as OFAC's, politically exposed persons lists and adverse media, both at onboarding and continuously afterwards, since lists change daily.
Transaction monitoring and case management. Watch account activity for patterns that suggest money laundering, fraud or sanctions evasion, investigate alerts and file suspicious activity reports when warranted.
Most early-stage fintechs buy jobs one and three first, because a sponsor bank will not let you onboard customers without them. Monitoring often arrives once volume grows, or when the bank's next audit finds gaps. Planning the stack around all four from the start saves a painful migration later.
How we chose these eight
We started with the identity, fraud and financial crime vendors in our compliance directory and kept the ones that (1) sell to fintechs and not only to large banks, (2) publish prices or have enough buyer data from Vendr, AWS Marketplace or G2 to estimate them, and (3) have verifiable customer numbers or funding. We weighted coverage of the four jobs above, developer experience and how easy the evidence is to hand to a bank partner. Prices are as of October 2026. Our methodology explains the rest.
We left out several good tools. Trulioo has the broadest global person and business database coverage (195 countries) and belongs on the shortlist for cross-border onboarding. AiPrise is a newer, cheaper option at $1.25 per KYC check. For crypto businesses, blockchain analytics from Chainalysis, Elliptic or TRM Labs sits alongside these tools rather than replacing them.

Two things move the real price more than the list price. The first is country mix: verifying a document from a country with poor database coverage costs more and fails more often. The second is the manual review rate. If 15 percent of applicants land in a review queue, the analyst hours can cost more than the software. Ask every vendor to run a sample of your real traffic before you sign, and compare pass rates rather than per-check prices.
Which tool fits which fintech
Pre-launch or seed-stage, consumer app, US only. Socure Launch or Persona Essential for identity, plus ComplyAdvantage Starter for screening. Total software spend can stay under $10,000 a year until volume picks up.
Global consumer product, including crypto. Sumsub covers identity, screening, monitoring and the Travel Rule in one contract and one integration. Add blockchain analytics for on-chain risk.
B2B fintech: payments, cards or lending for businesses. Middesk for US business verification, Persona or Sumsub for the owners and controllers, and Alloy if you need one place to make the decision and show the bank why.
Sponsor-bank fintech with several products. Alloy as the decision layer, with your choice of identity and screening vendors behind it. Banks are used to reviewing Alloy configurations, which shortens partner due diligence.
Scaling payments or money movement company. Monitoring becomes the hard problem. Unit21 if your compliance team wants to own and backtest rules. Sardine if fraud losses and AML alerts come from the same behavior and you want one team on one queue.
Rules that are moving in 2026
United States. On April 7, 2026 FinCEN proposed a rule to "fundamentally reform" AML/CFT program requirements under the Bank Secrecy Act. It replaces a July 2024 proposal that FinCEN withdrew, and its stated aim is risk-based programs and more consistent bank examinations. Comments closed June 9. Until a final rule is published, the existing program rules apply, and examiners still expect documented risk assessments and independent testing. The software you buy should make it easy to show why each threshold and rule exists, because that is where a risk-based regime puts the burden.
Beneficial ownership reporting to FinCEN under the Corporate Transparency Act was narrowed in March 2025 to exclude US-formed companies. That does not change your own customer due diligence duty to identify the beneficial owners of business customers. KYB tools are still required.
European Union. The EU's single AML rulebook is arriving in stages. The new authority, AMLA, was established in June 2024, is publishing technical standards on customer due diligence and monitoring through 2026, and will start directly supervising the highest-risk institutions in January 2028. The AML Regulation becomes binding on obliged entities from July 2027. If you operate in several EU countries, expect your onboarding rules to converge on one standard, and ask vendors how they will track AMLA's final standards.
Crypto. The EU's transfer of funds regulation now covers crypto-asset transfers, which means the Travel Rule applies to crypto service providers. Sumsub and several blockchain analytics vendors support it natively.
Mistakes we see in fintech KYC rollouts
Choosing on per-check price alone. A vendor that is $0.30 cheaper but sends twice as many applicants to manual review is more expensive.
No ongoing screening. Screening only at onboarding misses customers who are sanctioned later. Make sure continuous monitoring is in the contract.
Rules nobody can explain. Examiners ask why an alert threshold is $3,000 and not $5,000. Keep the reasoning and the backtest with the rule.
Collecting more data than you can protect. ID images and selfies are sensitive. Check retention settings and delete what you do not need. Your own SOC 2 program will ask about it.
Ignoring the bank's requirements document. Most sponsor banks publish minimum KYC and monitoring standards for partners. Map vendors against it before running a bake-off.
What is the difference between KYC and AML software?
KYC software verifies who a customer is at onboarding: documents, selfies, database checks and, for businesses, registry records. AML software watches what happens afterwards: it screens customers against sanctions and PEP lists on an ongoing basis, monitors transactions for suspicious patterns and helps analysts investigate alerts and file reports. A fintech needs both, and some vendors such as Sumsub and Sardine sell both.
How much does KYC verification cost per check?
Published 2026 prices range from about $0.80 to $1.85 per verification for document and selfie checks: Socure Launch from $0.80, Sumsub from $1.35, AiPrise from $1.25. Business verification costs more, roughly $2 to $5 per check at Middesk according to Vendr. Most vendors add monthly minimums, and enterprise contracts are priced on annual volume.
Do fintech startups need a BSA/AML program?
If you are a bank, money services business, broker-dealer or another financial institution under the Bank Secrecy Act, yes. If you operate through a sponsor bank, the bank holds the license but will contractually require you to run KYC, screening and monitoring to its standard, and its examiners review your program. In practice the obligation reaches you either way.
What is changing in US AML rules in 2026?
On April 7, 2026 FinCEN proposed a rule to reform AML/CFT program requirements under the Bank Secrecy Act. It withdrew and replaced a July 2024 proposal and aims to make programs more risk-based and examinations more consistent. Comments closed on June 9, 2026. It is still a proposal, so current program rules apply.
What is changing in EU AML rules?
The EU's AML package created a new authority, AMLA, which was established in June 2024 and will begin directly supervising the highest-risk institutions in January 2028. The AML Regulation becomes directly binding across member states from July 2027, replacing national variations of customer due diligence rules with one rulebook.
Can one vendor cover KYC, KYB, screening and monitoring?
Several claim to, including Sumsub, Sardine and Alloy through its partners. One vendor simplifies contracts and data flows. The trade-off is that you accept its weakest module. Many fintechs run a best-in-class identity vendor and a separate monitoring tool, and use an orchestration layer like Alloy to tie them together.
What should I ask a KYC vendor before signing?
Ask for pass rates and manual review rates by country on a sample of your real traffic, the full list of supported document types, monthly minimums and overage pricing, how they handle data retention and deletion, whether ongoing monitoring is included or extra, and what audit logs your bank partner or regulator can see.
Prices and ratings come from each vendor's public pricing pages and review sites as of October 22, 2026. Vendors change pricing often, so confirm with a quote. Nothing here is tax or legal advice.
