Case study: NorthLoop
Background
NorthLoop sells contracted climate-data feeds to ten of the top twenty global insurers. Their service-level agreement is 99.95% availability, contractually owed.
The problem
NorthLoop's previous reliability stack was a mix of CloudWatch alarms, Datadog dashboards, and a quarterly Excel spreadsheet shared with customers. The reports took 12 hours of an SRE's time per quarter to assemble, and customers had a hard time verifying the numbers.
What we built together
In May 2025 NorthLoop adopted DevFlow with a per-customer SLO. Each contracted endpoint became its own SLO; each customer got a private status page reflecting only their own SLOs. Quarterly reporting became a one-click PDF export.
Results
| Metric | Before | After |
|---|---|---|
| Quarterly report build time | 12 hours | 5 minutes |
| SLO attainment auditability | opaque | public per customer |
| Customer escalations on reliability | 8 / quarter | 1 / quarter |
| Time to first burn-rate alert | 14 min | 47 sec |
“When the contract says 99.95, you need a system that doesn't lie. DevFlow shows the math.”
NorthLoop has since renewed all eight Q3-expiring contracts, and the platform team has hired two more engineers on the back of being un-blocked from manual reporting work.
