Powering platform teams at
Built by ex-Stripe and Vercel engineers who got tired of paying $40k a month to read flame graphs.
Most monitoring is sold to the VP who buys it and resented by the engineer who uses it. Halo is built the other way around. Keyboard-first. One query language. No "agentless" footnotes that mean "agentful." If you’re the person paged at 3am, you’re who we built it for. The VP can still log in once a quarter to look at the bill.
We cut our observability bill 71% and our mean-time-to-detect went from 9 minutes to 38 seconds. The migration took a Wednesday afternoon.
Every plan includes traces, logs, metrics, RUM, alerting, SSO and SOC 2. You only pay for the events you actually ingest.
For side projects and evaluations.
For shipping engineering teams.
For platform teams running billions of events.
One bill, one SDK, one query language. Datadog is six products bolted together with six bills. Honeycomb is wonderful for traces and a thin layer of everything else. Grafana Cloud is open-source software you still have to operate. Halo is one tool for the entire signal pipeline, sold flat-rate per event.
For most teams: an afternoon. We ship import jars for Datadog metrics, OpenTelemetry passthrough, and a single shim script that aliases your existing query selectors to ours. The largest migration we’ve done so far moved 2.1B events/day in 9 hours.
Yes — we are OTel-native ingest. Bring your existing OTel collector or our SDK. Same signals, same semantics, no lock-in.
EU and US ingest endpoints. Customer chooses residency at signup. Data never leaves the chosen region. SOC 2 Type II audited by Prescient Assurance.
Shared Slack channel on Team and Scale plans, average first response 9 minutes during business hours. Every founder reads every ticket. On-call rotation is staffed by engineers, not a tier-1 funnel.
