"We investigate every single Sentry alert - that's non-negotiable. Struct lets us do that without burning engineering hours on manual triage. Our senior engineer got his time back to focus on AI product work, and the rest of the team picked it up naturally."
Siva Sooriyan
CTO, Arcana
The Challenge
Arcana's team was getting hundreds of high priority Sentry alerts monthly, and all of them had to be investigated and triaged. In fintech, you can't ignore exceptions when live portfolio analytics are at stake.
One senior engineer carried most of the burden. Every morning, he’d spend hours on exception cleanup, with individual investigations averaging 10-45 minutes each (longer for major incidents) - 15+ hours per week on Sentry triage alone. Newer engineers couldn't meaningfully contribute because effective triage required deep institutional knowledge about the codebase and infrastructure that lived in one person's head.
The Results
Triage time dropped from hours to <10 minutes per day. The on-call engineer now reviews Struct's investigation output instead of manually querying logs and cross-referencing code. As confidence in Struct grew, investigation coverage scaled 17x while maintaining an >80% helpful investigation rate.
"I sometimes skip Sentry entirely now — I just read the Struct output and pass it to the relevant person. Morning exception cleanup went from taking me an hour to about 10 minutes. And it helps our newer engineers triage issues they wouldn't have been able to handle on their own before."
Yash
Sr. Engineer, Arcana
The team's senior engineer got his time back to focus on higher-value work (like leading Arcana's AI agent initiatives) instead of spending hours a day on alert triage. A newer engineer was also successfully onboarded onto on-call, leaning on Struct's investigations to jumpstart understanding and triage. The broader team has also started using and referring to Struct investigations, with # of users organically 10’xing after the pilot.
