Headquartered in New York, HIFI is a software platform that helps companies build financial products on stablecoins.
HIFI works with institutions, fintechs, exchanges, and platforms that are bringing stablecoins into everyday financial products. That includes use cases such as cross-border payouts, programmable treasury, marketplace flows, and fiat on/off-ramps.
The platform provides the infrastructure needed to run these products in production, including APIs, developer tooling, access controls, programmable workflows, and observability. It connects licensed banking partners and tokenized money networks, giving customers access to both traditional payment rails and onchain infrastructure through one integration.
This allows teams to build once on HIFI and operate across blockchain networks such as Ethereum, TRON, Solana, Polygon, and Canton, as well as payment rails including ACH, RTP, FedNow, Fedwire, SWIFT, and Visa Direct.
The Challenge
The stablecoin infrastructure market moves quickly. Platforms operating across multiple blockchain networks, payment rails, and jurisdictions face growing compliance complexity as they expand into new markets.
The team recognised early that manual KYC and KYB processes would eventually become a bottleneck. Even at moderate volumes, manual verification slows onboarding, creates operational overhead, and pulls compliance teams away from higher-priority work. Rather than waiting for those problems to appear at scale, HIFI decided to build automated verification and monitoring into its infrastructure from the beginning.
Why Sumsub?
HIFI reviewed several providers when building its compliance setup, including vendors already well-established in the digital assets space. But being known in the market wasn’t enough. The decision came down to whether it could support HIFI’s specific operating model. The main requirement was flexibility. HIFI needed a platform that could integrate with its existing tools and support custom compliance workflows rather than fixed, standard flows.

We did not want to accept a one-size-fits-all approach that most vendors typically provide. Sumsub's ability to integrate our tools and flexibility in providing the custom solutions we're looking for was key in us going with them as our primary vendor.
This made Sumsub a fit for the way HIFI wanted to build compliance: not as a standalone process, but as part of the broader infrastructure.
The Solution
HIFI uses Sumsub as a centralized risk management platform. The platform combines several modules that work together across different stages of the customer lifecycle within a single setup, including:
- KYC for onboarding and verifying individual users
- Business Verification for partners onboarding, including expanded corporate registry checks
- AML Screening across both KYC and KYB flows, covering sanctions, PEPs, watchlists, and adverse media
- Transaction Monitoring and Travel Rule for real-time screening of counterparties, payment data, and transaction activity
- Fraud Prevention, including fraud detection solution and risk scoring to identify suspicious patterns early and help teams get ahead of potential issues before they escalate
- Case Management for handling investigations, alerts, audit trails, and regulatory reporting

What’s been useful for us is that the platform fits into the way the team actually works. We can adjust workflows as requirements change and get a clearer overview of alerts and investigations that gives the team more room to focus on more strategic compliance work.
For HIFI, the value is not only in the individual tools, but in how they work together. Now, during onboarding, AML checks are part of the KYC and KYB flows. After onboarding, Transaction Monitoring helps the team review customer activity and risk signals over time. Acting as the operational layer that connects these workflows, Case Management gives the team a central place to review alerts, follow investigation history, and prepare reports when needed.
This helps HIFI keep compliance workflows organized as the platform scales across different networks, payment rails, and jurisdictions.
The Results
The clearest impact has been time saved across compliance operations. HIFI has reduced the amount of manual work required for tasks such as business due diligence and preparing audit-ready reports, saving the compliance team hundreds of hours.

We’re very happy with the platform. It has saved our compliance team hundreds of hours that would otherwise have been spent on manual work, especially tasks like business due diligence and preparing audit-ready reports. We also believe Sumsub’s fraud detection solution will be key as we scale, helping us get ahead of potential issues before they appear.
Median verification time for both user and partner onboarding now sits at around 52 seconds, while approval rates remain above 82%.
More broadly, the benefit has been operational consistency. With verification, AML screening, transaction monitoring, case management, and reporting connected within one setup, HIFI can keep compliance workflows more structured as it expands globally.
Future plans
HIFI is expanding globally, adding support for new payment corridors, networks, and jurisdictions as demand for stablecoin infrastructure grows.
Each new market adds regulatory complexity. For HIFI, the compliance foundation built with Sumsub is what makes that expansion manageable: rather than rebuilding verification and monitoring workflows for every jurisdiction, the team adapts its existing setup to local requirements.
