What Core Banking Systems Does MANTL Integrate With?
MANTL integrates with major U.S. core banking systems—including platforms like Fiserv Premier, Horizon by FIS, and SilverLake by Jack Henry—through a core-agnostic, API-first architecture. That means you can modernize digital account opening and onboarding without ripping and replacing your core, and connect marketing programs directly to funded accounts and balances.
MANTL is core-agnostic, with production integrations to leading U.S. core banking platforms used by community and regional banks. This includes systems like Fiserv Premier, Horizon by FIS, and SilverLake by Jack Henry, along with additional cores that support modern, API-based connectivity. In practice, that means MANTL can sit on top of your existing core, synchronize customer and account data in real time, and orchestrate digital account opening and onboarding without forcing a risky, big-bang core conversion.
Why MANTL + Core Banking Integration Matters
Designing a MANTL + Core Integration Blueprint
Use this blueprint to understand how MANTL plugs into your core banking system, and how that integration supports account opening, onboarding, and growth marketing.
Discover → Assess → Design → Build → Launch → Optimize
- Discover your current core footprint: Identify your primary core (e.g., Fiserv Premier, Horizon, SilverLake), add-on modules, and any middleware or service buses already in place.
- Assess integration options: Document available APIs, batch interfaces, web services, and event streams from the core, along with security and change-management constraints.
- Design the integration pattern: Map how customer, account, transaction, and product data should flow between MANTL, the core, CRM, and analytics tools, including error handling and retries.
- Build and certify the connection: Configure MANTL’s core connector, stand up non-production environments, and validate end-to-end flows (application, decisioning, account opening, funding).
- Launch with guardrails: Roll out in phases, starting with targeted segments or product lines; enable monitoring around approval, funded, and abandonment rates tied back to core events.
- Optimize for growth: Use core-fed signals (funding, balance milestones, usage) to trigger onboarding, cross-sell, and retention journeys in your revenue marketing stack.
- Plan for future core changes: Treat the integration pattern as reusable IP so you can adapt to core upgrades, new modules, or eventual core conversions without restarting from zero.
Core Integration Capability Maturity Matrix
| Capability | From (Ad Hoc) | To (Integrated) | Owner | Primary KPI |
|---|---|---|---|---|
| Core Connectivity | Manual file drops or re-keying into the core. | API- or message-based integration between MANTL and your core (e.g., Fiserv, FIS, Jack Henry). | IT / Core Ops | Straight-Through Processing (STP) Rate |
| Account Opening | Branch-heavy, paper or PDF workflows; long cycle times. | Digital-first, omnichannel account opening with automated core booking and funding. | Digital Banking | Approval-to-Funded Rate, Time-to-Funding |
| Customer & Account Data | Conflicting records in core, CRM, and online banking. | Unified golden record with consistent IDs across MANTL, core, CRM, and analytics. | Data / RevOps | Match Rate, Duplicate Reduction |
| Risk & Compliance | Manual CIP/KYC checks and after-the-fact reviews. | Embedded KYC/KYB, OFAC/sanctions, and fraud checks that gate core account creation. | Risk / Compliance | Exception Rate, Fraud Losses |
| Marketing Activation | Email campaigns triggered only by form fills or static lists. | Lifecycle programs triggered by core events (funding, balances, product mix, dormancy). | Marketing / Growth | Funded Accounts, Products per Household |
| Analytics & Attribution | Click and traffic metrics only. | Closed-loop reporting from marketing touchpoints to core-booked accounts and balances. | Analytics / Finance | Cost per Funded Account, ROMI |
Client Snapshot: Integrating MANTL with a Legacy Core
A regional bank running on a legacy core wanted to grow digital deposits without a risky core conversion. By deploying MANTL on top of its existing core, the bank stood up API-based account opening, pushed customer and account data back into CRM and marketing automation, and tied campaigns to funded accounts. Within months, the bank improved digital approval-to-funded rate and shortened time-to-first-transaction while maintaining strict KYC/KYB standards.

When your MANTL integration is wired into the core, every application, approval, and funded account becomes a measurable signal you can act on. That’s how you turn a core integration project into a repeatable revenue marketing system.
