How MFStack, Fintech Primitives, and Cybrilla Work Together to Power Mutual Fund Apps
An end-to-end explanation of how MFStack, Fintech Primitives, and Cybrilla combine to power modern, compliant mutual fund apps—covering roles, architecture, and real-world distribution flows.
Introduction
Modern mutual fund platforms are no longer built by a single system. They are assembled ecosystems, where each layer specializes in doing one thing well.
This article explains how MFStack, Fintech Primitives, and Cybrilla work together to enable fast, compliant mutual fund app development.
The Three-Layer Architecture (At a Glance)
- MFStack → User experience & workflows
- Fintech Primitives → Mutual fund infrastructure & APIs
- Cybrilla → AMC connectivity (RTA / ONDC Seller side)
Each layer is independent—but designed to work together seamlessly.
Role 1: MFStack — Experience & Distribution Layer
MFStack focuses on everything users interact with:
- Investor web & mobile apps
- Distributor dashboards
- Digital onboarding & KYC journeys
- Assisted transactions (DIT)
- White-label branding
- SDKs & embeddable workflows
MFStack owns UX, conversion, and adoption.
Role 2: Fintech Primitives — Mutual Fund Infrastructure
Fintech Primitives powers the regulated core:
- MF transaction APIs
- SIP lifecycle management
- Order validation & status handling
- Compliance-aligned logic
- Reporting & reconciliation data
This layer ensures reliability, correctness, and scale.
Role 3: Cybrilla — AMC & Network Connectivity
Cybrilla handles the AMC-facing side:
- RTA gateway integrations
- AMC order routing
- ONDC Seller App / POA role
- Standardized seller-side workflows
This abstracts AMC-by-AMC complexity.
How a Typical Transaction Flows
- Investor initiates investment via MFStack app
- MFStack validates UX-level rules & consent
- Fintech Primitives processes the MF transaction
- Cybrilla routes the order to AMC / RTA or ONDC Seller
- Status & reports flow back to MFStack UI
Each system does what it’s best at.
Why This Separation Matters
This architecture delivers:
- Faster time-to-market
- Lower compliance risk
- Easier upgrades & regulation changes
- Flexibility to switch routes (RTA ↔ ONDC)
- Better focus for product teams
No single system becomes a bottleneck.
Who Benefits from This Model
- Independent distributors
- Wealth management firms
- Fintech startups
- ONDC buyer apps
- AMCs launching digital channels
Everyone gets speed without sacrificing compliance.
RTA Today, ONDC Tomorrow
One major advantage:
- Start with the Cybrilla RTA route
- Expand to ONDC later
- Keep the same MFStack UX
- Keep the same infra contracts
The experience stays constant while infra evolves.
Conclusion
Modern mutual fund apps are not built monolithically.
They are powered by:
- MFStack for experience
- Fintech Primitives for infrastructure
- Cybrilla for connectivity
Together, they enable faster, safer, and more scalable mutual fund distribution.
