Investing app with interactive financial lessons and gamified rewards to help users build wealth.
Bloom is a fintech app for employee investing (think “Robinhood for payroll” with gamified lessons).
Bloom wanted to offer paper trading (simulated stock trading) so users could practice without real money. They needed quick integration of market data and trading APIs.
Horizon Labs built the paper trading feature. Key steps:
The feature was delivered in approximately 2 months. Teen users could trade in a risk-free environment, greatly enhancing product engagement. The groundwork we laid also opened the door for future Alpaca collaboration.
Users now have a safe sandbox for investing. Bloom’s CTO reports this accelerated new-user growth. Bloom’s co-founder commended HL for swift, high-quality delivery.
Built paper trading end-to-end: Alpaca paper-trading API integration, trade simulation UX, and real-time portfolio updates. Delivered in ~2 months.
Node.js backend, React (if any frontend changes).
“Horizon Labs team is one of the most technically gifted leaders and engineering teams I've ever worked with! They are swift executors and also generally very likable people who are fun to work with. We are very fortunate to have worked with them!”
