Messages that create outcomes.

Messaging apps all share the same inbox shape. Most of what we send is waiting on someone: a question, a poll, a request, a plan. Casbu upgrades the traditional inbox and makes messages actionable, succinct and organized.

One card. One tap. The response stays pinned to the message. Time-sensitive casbus rise to the top. Tap VIP mode and the urgent casbus come one at a time. Deadlines hand the outcome to the sender. Work with people who aren’t on Casbu by email or SMS.
