The collaboration will embed Sardine's device, behavioural and transaction risk signals across deposit account opening, funding, payments and authentication workflows. The integration targets high-risk flows including KYC and KYB verification, AML, and ACH and wire transactions. By combining Sardine's technology with Linker's orchestration controls, community banks gain access to enterprise-grade fraud detection capabilities typically available only to major national institutions. The partnership aims to reduce manual review workloads, improve customer conversion during account opening and funding, and provide faster threat detection. Sardine's platform already serves clients including FIS, GoDaddy and Brex.
Linker Finance and Sardine partner to deliver real-time fraud prevention for community banks. PR Newswire Integration brings Sardine's device, behavioral and transaction signals into Linker's platform to protect retail and business customers LOS ANGELES, March 6, 2026 /PRNewswire/ - Linker Finance, a modular platform purpose-built for community banks, today announced a strategic partnership with Sardine, the leading agentic risk management platform designed to protect companies from financial crime. Through this partnership, Linker Finance will integrate advanced real-time fraud detection into its retail and business banking offerings. The collaboration enables Linker to apply Sardine's device, behavioral and transaction risk signals across deposit account opening, funding, payments and authentication workflows, improving early threat detection, reducing manual review workload and strengthening depositor protection. The integration focuses on high-risk retail and commercial flows, including deposit account opening and funding, KYC and KYB verification, AML, ACH and wire transactions. By combining Sardine's technology infrastructure signals with Linker's orchestration and customer intelligence controls, banks gain faster, richer insight into risky activity. "Community banks remain the backbone of local economies, but are often lacking the sophisticated anti-fraud and risk management technologies of major national banks," said Ravi Loganathan, GM of Banking at Sardine. "By integrating Sardine with Linker's retail and business banking workflows, we're giving community institutions enterprise grade protection that will protect their customers and communities with confidence." "Combining Linker's retail and business banking capabilities with Sardine's advanced risk signals transforms how community banks combat payment and account fraud. By applying Sardine's real-time scoring to check processing, ACH and wire transactions alongside AML monitoring, banks gain faster threat detection and automated response options, which reduces manual review workload for bankers, lets teams prioritize customer relationships and strengthens protection for depositors," said Jorge Garcia, CEO and Co-Founder of Linker Finance. "As a technology organization, we focus on integrations that are fast, reliable and measurable. Sardine's low-latency APIs and robust device and behavioral signals let us automate risk decisions in real time across retail and commercial flows, improve customer conversion during funding, and significantly reduce manual workload for operations," said Pete Torres, EVP, CIO at Linker Finance.
Gr4vy partners with Sardine to embed fraud and AML into their platform. Gr4vy. Enterprises can now access AI-driven fraud prevention and compliance tools directly through Gr4vy's payment orchestration layer San Mateo, February 17, 2026: Gr4vy, the cloud-based payment orchestration platform, today announced a new integration with Sardine, the leading agentic platform to fight financial crime. The integration allows Gr4vy customers to embed fraud solutions, including real-time transaction monitoring, fraud interdiction, and BSA/AML compliance tools, directly into their payment orchestration stack without additional development. The announcement comes as fraud becomes an ongoing operational reality for merchants, with 98% of businesses experiencing at least one form of fraud each year. Sardine supports enterprises operating in more than 70 countries by detecting fraud in real-time using device intelligence, behavioral biometrics, and machine-learning models. To date, Sardine has protected over $1T in transaction volume for 565M consumers and 2.7M businesses. Integrated into Gr4vy's orchestration layer, Sardine's fraud fighting capabilities can now be activated through a single connection, simplifying how merchants manage risk across payment flows. Gr4vy merchants can automate fraud decisions, reduce manual reviews, and limit false positives while maintaining fast checkout experiences. Risk logic can be updated without disrupting payment routing or performance, helping teams respond more efficiently as fraud patterns evolve. John Lunn, Founder and CEO of Gr4vy, said the integration reflects the growing need to treat fraud as part of the core payment infrastructure rather than a separate system. "Fraud prevention shouldn't slow down payments; it should improve how decisions are made," said Lunn. "By integrating Sardine, merchants can manage fraud detection and payment orchestration together, while preserving the flexibility and speed required to operate at scale." "When you have payments, you will inevitably have fraud. And as payment ecosystems become more complex, merchants need solutions that can address risk and compliance without impacting performance," said Soups Ranjan, CEO and Co-Founder of Sardine. "Our partnership with Gr4vy allows merchants to run fraud and AML controls through a single integration, simplifying how risk is managed across payment methods and geographies." Together, Gr4vy and Sardine provide a more integrated approach to managing fraud and risk. Merchants can leverage device fingerprinting, behavioral biometrics, and real-time webhook updates to detect and respond to suspicious activity across payment flows. Gr4vy's event streaming shares transaction outcomes with Sardine's fraud models to continuously improve detection accuracy over time. As a result, merchants can strengthen fraud protection while improving acceptance rates and reducing friction and costs across their payments stack.
