App developers targeting Brazilian users struggle to integrate with local financial infrastructure like Pix payments.
Create developer-friendly SDKs and APIs that abstract away Brazil's complex banking regulations and payment systems.
Monetize through API calls or percentage of processed transactions. Target both Brazilian startups and international companies expanding there.
Start with Pix integration, then add other local financial services like boleto bancário.
Risk: Brazilian regulations change frequently and local competitors may undercut pricing.
