Rolling out Fin in Slack and over email was a big moment for us. These are two of our most critical support channels—Slack especially, since it's so public—so we needed it to be flawless. I was amazed at how smooth the rollout actually was. Within days, Fin was confidently resolving a high percentage of questions across both channels.
