We were running Sentry on a 14-service Go monorepo. Alerts were noise. Three weeks after switching to Stacktrace, our on-call rotation went from 6 pages a night to 1. The grouping is genuinely different.

Our Series B due diligence included an uptime review. I pulled 90 days of Stacktrace dashboards in 3 minutes and showed four nines. The investor said it was the cleanest observability story they'd seen at seed stage.
