Founder & CEO
Client Introduction
A well-funded US-based startup aiming to disrupt the retail investment space. Their vision was to create an iOS-first platform that uses AI to provide personalized investment advice and automated portfolio management for millennial and Gen Z users.
Problem
The client had a brilliant concept and a team of data scientists, but they lacked the in-house iOS development and backend engineering capacity to build a secure, scalable, and user-friendly application quickly enough to capture market share. They needed a partner who could move at startup speed while ensuring institutional-grade quality and security.
Key Challenges
Speed to Market
The need to launch an MVP within 4 months to secure the next funding round.
AI Model Integration
Integrating their proprietary Python-based ML models into a high-performance mobile experience.
Bank-Level Security
Implementing robust security measures, including biometric authentication and data encryption, to build user trust.
Real-Time Data
Integrating with multiple financial data APIs for real-time stock quotes and market news.
Our Solution
We deployed our "AI / ML Rapid-Prototype Pod," a specialized team designed for speed and innovation.
🎯 MVP-Focused Strategy
We worked with the client to aggressively prioritize features for an MVP, focusing on the core value proposition.
🧠 Backend for AI
Our backend team containerized their Python ML models and exposed them via a secure, low-latency REST API built on AWS Lambda (serverless).
📱 Native Swift UI
The front end was built in native Swift using SwiftUI to accelerate UI development and create a modern, fluid user experience.
🔒 Secure by Design
We integrated Face ID/Touch ID from day one and used Stripe for secure identity verification and bank account linking.
Implementation and Execution
UI/UX Design Sprint
Utilized a dual-track Agile process: one track for the iOS app, one for the backend API.
Project Sprints
Set up a CI/CD pipeline using Fastlane and Jenkins for automated daily builds to TestFlight.
Cross-Platform Dev
Employed a T&M engagement model to provide the flexibility needed for a rapidly evolving startup project.
AI Model Training
The iOS team worked in close collaboration with the client's data scientists via a shared Slack channel.
Communication & Alignment
Conducted rigorous performance testing to ensure real-time data feeds were displayed without lag.
Successful Launch
Successfully passed a third-party penetration test before launch.
Positive Outcome
🚀 MVP Launched in 16 Weeks
The MVP was successfully launched in the App Store, meeting the aggressive deadline.
💰 Secured Funding
The successful launch and positive early traction were instrumental in the client closing their $25M Series B funding round.
⭐ High User Ratings
The app's intuitive design and snappy performance earned it a 4.9-star rating.
📈 Scalable Foundation
The architecture we built allowed the client to seamlessly add new features and scale to over 100,000 users in the first year.
