As the solo product designer for KaChing, I designed a reverse split arbitrage automation system. The goal was to improve the efficiency of this niche passive income strategy by turning manual tasks into a seamless workflow. By simplifying prompt engineering and automated execution, I helped the platform achieve 600% user growth within 3 months.
Period: 2 months
Background: Reverse split arbitrage is a high yield passive income strategy that remains inaccessible to most due to its extreme manual complexity. Potential users are often discouraged by the tedious and error prone execution process, especially when managing multiple brokerage accounts. Manually executing trades across various platforms is highly inefficient and significantly limits the ability to scale this strategy effectively.



Strategy: I designed a comparative logic flow that visualizes the transition from a manual to an automated experience.
Workflow Optimization: We replaced hours of manual scanning and calculating with a seamless AI triggered execution loop. This system removes the friction of managing multiple accounts, turning a tedious process into a simplified automated cycle.

Multiplying Impact: Designed a multi-account management system that encourages users to link and open more brokerage accounts.
Revenue Driver: Increased the "Profit Surface Area" for users, which in turn maximized the platform's subscription and transaction-based revenue.


By simplifying the core value proposition for immediate buy-in and integrating the institutional credibility of AInvest Holdings Inc. directly into the UI, this "trust-first" design approach fueled a 600% user growth within the first 3 months of launch.
