Case Study: Launched a Cross-Platform Fintech MVP in 5 weeks

Prospero.AI is a disruptive fintech startup founded by a former Wall Street hedge fund manager. With a mission to democratize access to financial markets, Prospero.AI aims to level the playing field using AI-powered technology that translates millions of real-time data points into simple, actionable investment insights.

Their platform challenges the status quo, where hedge funds benefit from exclusive data access while everyday investors are left behind. As the team at Prospero.AI puts it:

“We turn complex trading patterns into stock insights that earn you more wins. Hedge funds don’t want you to have this, but our AI-driven analysis offers clear, proven signals that consistently outperform the S&P 500.” 

Prospero.AI approached React Coder with a bold objective:

Build and launch a feature-rich mobile MVP for both iOS and Android in just five weeks, in time for a major fintech conference.
 

But this wasn't the only challenge:

• Lack of detailed specifications: The initial input was limited to a rough outline. We had to interpret, design, and structure the user experience from the ground up.
   
• Full UI overhaul: A complete redesign was required to modernize the app’s interface and improve usability.
   
• Accessibility barriers: The app needed to become more intuitive and appealing to mainstream users—not just fintech-savvy early adopters.
   
• User onboarding & education: To reduce the learning curve, the app needed built-in knowledge-sharing features that could onboard and guide new users.
   
• Tight deadlines: Delivery had to align with a November conference—a critical user acquisition opportunity.
   
• Investor confidence: The MVP needed to appeal to both early adopters and potential investors, with an emphasis on usability, value, and growth potential.

 Our dedicated team — consisting of frontend developers, QA testers, and a project manager — mobilized quickly and delivered results in record time:

1. Rebuilt the app UI from scratch, creating a cleaner, more intuitive user interface tailored to investor needs.
    
2. Redesigned the UX to simplify complex AI-generated signals and make them more accessible to everyday users.
    
3. Integrated in-app knowledge-sharing features to reduce onboarding friction and improve user engagement.
    
4. Achieved full MVP development and deployment for both iOS and Android — all within the 5-week deadline.
    
5. Utilized React Native to maintain a single codebase, reducing development time and costs without compromising quality.

• ✅ MVP delivered ahead of schedule and launched in app stores in time for the critical November conference.
   
• ✅ Project completed under budget, with no compromise on quality.

React Coder's rapid delivery, technical precision, and deep UX understanding enabled Prospero.AI to launch a robust fintech MVP in just five weeks — helping them impress users, attract investors, and position themselves for long-term growth in a competitive industry.
