GovTech firm modernized 40-year-old COBOL platform with thinkbridge—now a secure, scalable SaaS solution built in just 11 months.
The client had built significant market share with a legacy utilities software platform that served as the operational core for GovTech clients—managing billing, finance, HR, and infrastructure mapping. Despite a loyal customer base, the platform’s age and technology stack were imposing significant barriers to growth, efficiency, and competitiveness. Specific challenges included:
thinkbridge took a systematic, value-driven approach to modernizing the platform—combining speed with reliability. Our approach addressed both short-term functionality needs and long-term scalability goals:
Cloud-Native, Multi-Tenant Architecture:
We re-architected the platform from scratch using Angular and .NET Core, hosted on AWS. The result was a modern SaaS foundation that allowed multiple municipalities to be served on a single, securely partitioned instance—driving down costs and simplifying operations.
Modular Design for Core Business Functions:
• Utility Billing Hub – to manage rate plans, consumption tracking, invoicing, and payment processing.
• Finance Hub – to handle general ledger, reporting, budgeting, and compliance needs.
• HR Hub – to streamline employee records, payroll, and administrative workflows.
• Maps Hub – to integrate GIS functionality and visualize infrastructure assets like pipelines and meters.
Unified User Experience: These modules were seamlessly integrated into a newly designed FrontDesk Portal, offering a single, intuitive entry point for GovTech users to manage day-to-day operations.
Zero-Disruption Migration: To reduce customer risk and friction, we developed a 1-click data migration middleware. This tool ensured complete and accurate transfer of historical data from legacy systems to the cloud with no disruption to ongoing operations.
Feature Parity + Strategic Enhancements: All existing core features were retained to maintain customer continuity, while forward-looking enhancements were added to reflect the client’s renewed product strategy.
End-to-End Execution: From architecture and development to deployment and ongoing maintenance, thinkbridge took full accountability—allowing the client to focus on growth and customer relationships instead of internal firefighting

• Complete Modernization in Record Time: Delivered a full platform rewrite in under 11 months, succeeding where previous partners failed—at a fraction of the cost and time.
• Seamless Transition from On-Prem to SaaS: Existing customers migrated with zero downtime and no retraining burden thanks to feature parity and thoughtful UX.
• Enabled Market Re-entry and Expansion: With a modern platform in place, the client regained momentum in sales conversations and won new municipal accounts previously out of reach due to legacy constraints.
• Reduced Operational Overhead: The new multi-tenant SaaS model eliminated the need to support disparate on-prem installations, improving deployment efficiency and support scalability.
• Strengthened Strategic Position: The modernization didn’t just level the playing field—it gave the client a platform to outpace legacy-bound competitors with faster innovation cycles and improved customer experience.
This engagement is a clear example of how thinkbridge tackles complex, high-risk modernization projects with confidence and clarity. Where others failed to execute, we succeeded by combining deep technical expertise, rapid delivery capability, and a pragmatic, business-first approach.
By transforming a rigid, aging, on-premise utilities platform into a modern, cloud-native SaaS solution, we not only helped the client protect their current customer base but also armed them with a competitive advantage to grow in an evolving GovTech landscape.
thinkbridge delivers not just technology—but outcomes. We help organizations unlock growth by turning legacy challenges into digital opportunities.
