Delivered a full-featured mobile payments app for PayMongo in just 8 weeks—50% faster than planned—using Flutter, internal accelerators, and agile delivery to meet tight budget, time, and quality targets.
The success of PayMongo’s mobile strategy hinged on four critical constraints:
Speed to Market: The mobile app needed to be delivered in under 4 months to meet internal roadmap and investor milestones.
• Platform Compatibility: The solution had to work flawlessly across iOS and Android devices to cater to a wide merchant base using different hardware.
• Budget Efficiency: As a Series A startup, PayMongo had to maximize return on investment while keeping development costs lean.
• Merchant Usability: The app had to deliver a frictionless, intuitive experience that worked reliably in varied network and device conditions—typical in underserved regions.
In short, PayMongo needed a way to move faster, deliver better, and spend less—without lowering the bar on quality.
We approached this challenge not just as a technical problem—but as a strategic execution mission. Our delivery model was anchored in the principles of velocity, precision, and stakeholder alignment.
1. Platform Acceleration with Flutter
We made a deliberate choice to build the app using Flutter, Google’s open-source UI framework. This gave us the power to:
• Reuse 90–95% of the codebase across platforms• Reduce development complexity and testing overhead
• Maintain design consistency and performance parity on both iOS and Android
Flutter enabled our engineers to work from a single source of truth, accelerating development while preserving high-quality UX standards.
2. Internal Accelerators to Cut Down Ramp-Up Time
Our proprietary UI component libraries, pre-configured CI/CD pipelines, and reusable code assets enabled us to:
• Slash setup and ramp-up time by over 40%
• Begin producing working features in week one
• Quickly implement core payment workflows including merchant onboarding, QR code generation, wallet integration, and transaction histories
These accelerators are part of our “Speed Without Sacrifice” engineering philosophy—develop once, deploy with confidence.
3. Agile Delivery with Tight Feedback Loops
Our delivery model emphasized fast, measurable iteration:
• Sprints every 2 weeks, with demo sessions at the end of each cycle
• Daily syncs between thinkbridge and PayMongo product leads
• Tight QA cycles with integrated automation to prevent regressions
This allowed us to adapt in real-time to changing priorities and incorporate feedback rapidly—without slowing down the development momentum.
4. Clear Communication, Shared Ownership
We worked as an extension of PayMongo’s product team, not just as an outside vendor. Our transparent communication approach helped ensure:
• Complete visibility into progress and blockers
• Alignment of goals, from product features to merchant experience expectations
• Trust-based collaboration, reducing friction and decision delays

Our approach translated into exceptional outcomes:
• Project delivered in 8 weeks—50% faster than the planned 16-week timeline
• 100% of core functionality shipped, including merchant registration, payment processing, QR code support, and digital wallet integration
• Cross-platform launch ready for both iOS and Android devices, using a single codebase
• Conducted pilot rollout with select merchants within days of completion
• Received strong feedback from both PayMongo’s internal teams and pilot users on performance and ease of use
• Maintained budget discipline, avoiding scope creep and staying within financial targets
The early pilot results indicated a high likelihood of faster adoption and lower support costs due to better user experience design and fewer platform-specific issues.
This engagement demonstrates what’s possible when smart technology choices are paired with a disciplined delivery model and a collaborative mindset.
By using Flutter and thinkbridge’s development accelerators, we delivered a fully functional, production-grade mobile app in half the typical timeline—without compromising scalability, security, or user experience. For PayMongo, this meant they could get to market faster, test with real merchants sooner, and keep their growth trajectory intact.
For thinkbridge, it was another proof point of how we help ambitious companies go further—faster.When the stakes are high, the budget is tight, and the timeline is non-negotiable, thinkbridge delivers.
