Software Development Bengaluru East, Karnataka 5,001–10,000 employees Privately Held

PhonePe operates India's dominant payments app (57+ crore registered users, 4+ crore merchant acceptance points) and is now broadening into insurance, lending, wealth management, and hyperlocal ecommerce. The tech stack is infrastructure-heavy—Linux, Nginx, HAProxy, MySQL, Aerospike, HBase, Elasticsearch—paired with polyglot backend (Java, C++, Go, Python) and mobile-first engineering (Kotlin, Android). Active adoption of LLMs (ChatGPT, Claude, Gemini) alongside core projects in infrastructure scaling and system-led offer issuance suggests a push toward AI-driven merchant tooling and personalization at massive scale.
