SimulationMaxxing: Nubank משלים 20× מהר עם סימולציות

תקציר מקורי באנגליתNubank serves 135 million customers, so an AI agent that mishandles a support conversation fails at scale. The talk opens with the result: five agents in production, higher customer satisfaction, and roughly 20 times faster shipping. Shreya Rajpal, CEO of Snowglobe, argues the thing that unlocked that pace was evals, and specifically simulated data standing in for real conversations. Good agent evals are hard because the data is multi turn and stateful, not single turn question and answer, and hand curating it and waiting on production to confirm can take forever. Snowglobe points at the agent and generates grounded simulations, a customer like Maria trying to order a credit card, complete with account context, tone, and intent, so you can ship, observe, simulate, and feed the results back
