Case Study: PromptWorks achieves faster, more reliable CI and lower maintenance costs with CircleCI

PromptWorks - Customer Case Study

PromptWorks is a software consultancy that builds custom web and mobile applications for clients from startups to Fortune 50. They required reliable CI/CD with automated testing on every branch so product owners could see working software quickly, but their previous Jenkins-based setup was a fragile, high-maintenance patchwork of jobs, plugins and scripts that caused downtime and slowed development.

Switching to CircleCI gave PromptWorks a simpler, scalable CI solution that treats feature branches as first-class citizens, enabling faster builds and tighter iteration cycles. The change reduced maintenance costs (about $1,500/month for one client), cut setup time billed at $200/hr for others, and became central to their deploys to AWS for a 30+ person team running 30+ tests/day across Ruby, Python and JavaScript stacks.
