Stone is a public payment processor and merchant platform built for Brazilian small and medium business owners. The company is heavily sales-driven—745 active sales roles against 31 engineering positions—and spending significant effort on key account growth and client acquisition, signaling a shift from transactional processing toward relationship-managed, high-touch enterprise coverage. Core infrastructure runs on Go, PostgreSQL, and GCP; mobile-first product development (Android, Kotlin, Swift, React Native) and emerging WhatsApp/Twilio integrations suggest a move into conversational commerce and embedded payments.
