Transforming Savings Access with a Personalized Financial Platform
Discover how we helped develop a modern savings and CD platform that streamlines onboarding, enhances transparency, and supports smarter financial decisions.
How Lumitech partnered with a fintech innovator to launch a U.S.-focused platform that simplifies access to high-yield savings options and enables users to make better financial choices.
About the Project
The platform was designed to solve a key problem in personal finance: finding and opening high-yield savings and CD accounts without friction or confusion. Traditionally, this process has been slow, inconsistent, and full of hidden fees or unclear terms.
This new solution centralizes multiple partner banks into one clean interface, offering users a way to discover, compare, and open accounts with clarity and ease — all while ensuring security and compliance.
Client Request
The client had a strong track record in the European fintech space and wanted to expand their proven model into the U.S. market. Their goals were to:
Build a multi-bank marketplace for high-yield savings and CD accounts
Offer Single Sign-On (SSO) capabilities for seamless onboarding
Display live interest rates, updated in real time from each institution
Ensure full transparency, with no hidden fees or misleading terms
Provide personalized guidance to help users make the most of their savings
The platform had to be simple enough for everyday savers, yet powerful enough to support long-term financial goals.
Approach
We worked in close collaboration with the client's leadership, design, and compliance teams to build a platform tailored to U.S. consumers. Our process included:
Market Localization Adapting the platform’s functionality to align with U.S. banking standards, partner integrations, and user expectations.
Design & User Experience Creating a modern, user-first interface that simplifies decision-making and makes financial actions feel effortless.
Technical Implementation Developing secure APIs to ingest rate data, connect with partner institutions, and deliver SSO experiences.
Agile Launch & Iteration Deploying in phases, collecting early feedback, and optimizing flows to increase conversion and retention.
Core Features
Multi-Bank Savings & CD Marketplace Users can explore and compare offers from multiple banks within one platform — with filters for rate, term, and account type.
Seamless Single Sign-On Access Instead of creating new logins for every account, users can apply and manage all their financial products with a single identity.
Live Rate Updates The platform automatically pulls updated rates and terms from each partner bank, ensuring accuracy and competitiveness.
No-Fee, Full-Transparency Model Clear disclosures, no volume-based penalties, and upfront visibility into how each account works.
Personalized Savings Recommendations Based on user input and behavior, the platform recommends the most relevant financial products to optimize yield and fit personal goals.
Challenges
Multi-Institution SSO Integration Integrating consistent and secure login flows across different partner banks required deep technical coordination and regulatory compliance.
Real-Time Financial Data Syncing Ensuring all rates and account details stayed current — across different data sources — meant building a flexible, high-availability data pipeline.
User Confidence & Clarity One of the biggest UX challenges was conveying trust and simplicity, especially to users unfamiliar with direct bank marketplace models.
Results
30% faster average onboarding time compared to traditional account applications
20% improvement in user engagement during early access and beta testing
High conversion rates attributed to transparent flows and clean design
These early wins laid a strong foundation for scaling the platform across new financial products and user segments.
Summary
This savings and CD platform is redefining how consumers approach personal finance. With a focus on speed, personalization, and transparency, it delivers a modern banking experience built around the user — not the institution.
