Company Background

FinFlow: Modernizing insurance at scale

FinFlow is a rapidly growing insurtech platform serving over 2 million users. With a team of 120 engineers spanning Product, Design, and Engineering, they handle complex policy management, claims processing, and real-time risk assessment.

The Product Context

Before adopting Modly, FinFlow relied on a legacy React component library maintained by a single senior developer. As the company scaled, the library became a bottleneck. New features were delayed because developers had to manually re-implement basic UI patterns or wait for the maintainer to fix critical bugs.

The design team used Figma for prototyping, but the gap between Figma and code was wide. Tokens were inconsistent, leading to a disjointed user experience across the web app and mobile SDK.

Team Structure

FinFlow operates on four squads: Core Platform, Claims, Policy, and Mobile. Each squad had its own copy of component libraries, leading to a "copy-paste" culture that introduced bugs and design inconsistencies.

The Challenge

Design debt was slowing down innovation

FinFlow's legacy architecture meant that changing a single button style required updates across four different repos. The team spent an estimated 30% of their engineering hours on maintenance rather than new features.

Fragmented Token System

Four squads used different color palettes, spacing scales, and typography settings. A "primary blue" in the web app might be a completely different shade in the mobile app.

Slow Release Cycle

Releasing a design update took 3-4 weeks due to manual code updates and testing in isolated silos. The team was effectively "reacting" to user feedback rather than proactively iterating.

Documentation Gap

Documentation was out of sync with the code. Developers often had to look at Figma or ask designers directly to understand how to use a specific component.

Vendor Lock-in

Custom React components were tightly coupled to their internal framework, making it difficult to share modules across the organization.

The Solution

Implementing Modly for unified design systems

FinFlow adopted Modly as their central source of truth, replacing their fragmented library with a composable module registry.

Module Migration

Using Modly's CLI, FinFlow imported their existing React components into a centralized registry. They organized 140+ components into logical modules (e.g., "Form Elements", "Data Display").

Token Unification

They connected their Figma design files to Modly. All tokens (colors, spacing, typography) were automatically synced to a single design token file, ensuring 100% parity between design and code.

Storybook Publishing

Modly's auto-generated documentation replaced their stale README files. Each module now has a live preview, prop types, and usage examples, instantly accessible to the whole team.

The Quote

"Modly turned our design system from a burden into a competitive advantage."

"We used to argue about button styles for two hours every sprint. Now, we define it once in Modly, and it just works. The reduction in friction has been incredible. We’re shipping features that users actually love, not just features that are technically possible."
