Great tech is not enough: building trust to get the most out of Temporal at Cash App

Abstract

Temporal arrived at Cash to solve a “code red” situation, unblocking the launch of a critical feature - monthly customer statements. The feature launched, but adoption did not grow as a result. The tools, support, and budget were in place, but Cash engineers were hesitant to use Temporal for anything other than trivial background jobs and maintenance work.

Today, Temporal is in the path of all user interactions with Cash App, all inbound and outbound transfers of money, third-party partnerships with Cash App Pay, and many of the systems that power risk and safety decisions in Cash App.

Reaching broad adoption from our first use case relied on meeting our engineers where they were and rethinking the “platform team” approach to supporting our customers.

In this talk we’ll tour the tooling/processes/team rituals we built at Cash as well as the sort of use cases we were able to drive as we built confidence in the platform.
