This is a fast-paced environment at the beginning of our journey, so we embrace uncertainty. We're constantly building new services and evolving existing ones, with experimentation being a key. We balance the "fail fast" principle to avoid analysis-paralysis, but we also take the time to understand the benefits of different alternatives before diving in. We're not afraid to make mistakes. We learn from them.
