Key quotes
Buying a car in India is a journey, not a transaction. For years, the experience depended on who picked up the phone. AI changes that. Today, we handle over a million conversation minutes a month through AI, giving every customer a high-quality experience at any scale.
I thought Codex would make our engineers faster. What surprised me was how quickly it spread beyond engineering. Product managers, finance teams, and even day-to-day workflows started changing. That is when I realised we had not just changed how we write code but had changed how the entire company thinks about getting work done.
Employees are increasingly building the tools they need instead of waiting for centralized engineering support.
