{prefix}{val}{suffix} {tag} Modernizing Legacy Cores. A {bankSize} regional bank with a core built on FIS Horizon. Data is gated behind a complex MuleSoft Anypoint middleware layer with a 14-month engineering backlog for new connectors. Integrated Root AI in 12 days using existing OData endpoints. Bypassed the middleware bottleneck to deliver real-time core data to RMs with zero additional engineering overhead. {s.prefix || ''}{s.n}{s.suffix} The CTO's Challenge The Business Wanted AI. Engineering Had No Capacity. The Commercial Banking heads needed advanced context bridging between their Salesforce pipeline and their FIS core banking reality. But the Chief Technology Officer was dealing with a 14-month backlog of data projects. They couldn't afford a heavy 9-month implementation consisting of building new middleware APIs, QAing data contracts, and mapping new fields into Salesforce. It needed to be lightweight, read-only, and leveraging existing infrastructure. If a vendor needs your engineering team to build a new connector, they're selling you a project, not a product. We built Root AI to inherit what's already there. "If an AI vendor tells me 'we just need to build a few custom connectors,' I show them the door. My team doesn't have the bandwidth to build bespoke integrations. Root AI's ability to inherit our existing OData definitions was the only reason this project was approved." {row.task} {row.label} The "Zero-API" Integration. How we bridged their legacy FIS Horizon core directly into Salesforce FSC without building any new middleware pipelines. Implementation Journey Zero Friction. 12 Days to Live Data. {phase.challenge} {phase.action} {phase.output} Measured Outcomes Architecture & Scale Results. *Results based on an anonymized deployment utilizing existing MuleSoft and Salesforce infrastructure components. "This was the first vendor deployment I've ever overseen where my engineering team did absolutely nothing. Built By Root's architecture literally plugged into our existing Salesforce External Services definition and just worked." Legacy Core. Modernized Instantly. See how we build a bridge to legacy systems like FIS, Fiserv, and Jack Henry without requiring 12-month transformation projects.
