Pingo AI

Pingo AI is building the future of language learning and AI companions.

We help millions of users build fluency through real conversations with an AI companion that knows their progress, adapts to their goals, and makes learning feel natural. Since launching in 2025, we’ve scaled to multi-million ARR and become one of Y Combinator’s fastest-growing consumer AI startups, backed by top-tier investors.

We believe the future of learning won’t feel like an app or a one-off tutor session—it will be an AI you build a relationship with. Our mission is to make Pingo the default way to learn a language worldwide.

We’re an extremely lean team shipping fast at the intersection of AI and consumer.

We run real-time speech pipelines, LLM orchestration systems, long-term memory retrieval, and high-throughput backend services powering millions of conversations. We’re solving challenges like:

• Making real-time AI conversations feel instant at scale
• Designing personalization and memory systems so learning adapts to each user
• Building a platform that’s reliable and engaging for millions of learners

You’ll directly shape how millions of people around the world learn and connect.
