NEW AI root-cause v2 is live — try it in your next incident

The on-call shift that doesn't end your weekend.

Throughline is an incident response platform that takes engineers from alert to root cause in under 90 seconds — without the 3am archaeology, the manual triage, or the ten-person Slack war room.

The problem

3:47am alerts shouldn't ruin Monday.

Most incident tooling was designed to wake people up. None of it was designed to keep them rested, focused, or productive on the other 167 hours of the week.

The 3am page that wasn't yours

You get woken up for a service you've never touched. Forty minutes of dashboard hopping later, you find out it was a deploy from another team. Sleep is gone. Trust is bruised.

Alert storms that drown signal

One root cause fires 47 downstream alerts. Your phone vibrates for an hour while you try to figure out which one actually matters. By the time you triage, customers have already tweeted.

Senior engineers burning out

The same three people end up in every war room. They're tired. They're interviewing elsewhere. And nobody else on the team has the context to take over when they leave.

How it works

From alert to root cause in under 90 seconds.

Four steps. No SQL. No grafting together six dashboards while your phone vibrates. The diagnosis engine does the archaeology so the on-call engineer can focus on the fix.

01

Detect

Ingest signals from every observability tool you already pay for. Correlate alerts across services into a single incident, not 47 notifications.

02

Route

Match the incident to the engineer who last shipped to that service — not whoever happens to be on rotation. Quiet hours respected, escalation built-in.

03

Diagnose

Throughline cross-references the alert against recent deploys, infra changes, and historical patterns. You get a ranked list of probable causes before you finish your coffee.

04

Resolve

One-click rollback, runbook execution, or war-room spin-up. Postmortem draft auto-generated from the timeline — review it Monday, not Sunday night.

The difference

Before Throughline vs. with Throughline.

What incident response actually looks like on a Tuesday at 2pm — and on a Saturday at 3am.

Before — the chaos

Six dashboards, three Slack channels, one tired engineer.

  • 47 noisy alerts for a single underlying cause
  • On-call paged for services they've never touched
  • 43 minutes of dashboard hopping before root cause
  • Postmortem written Sunday night, half remembered

What you get

Built for the way modern teams actually ship.

Every feature ships because it answers a 2am question we've been asked too many times to count.

Smart alert correlation

Group related signals into a single incident automatically. Cut noise by 92% on the first day, without writing a single suppression rule.

AI root-cause analysis

Throughline cross-references deploys, infra events, and historical incidents to rank likely causes — with the exact commit SHA to look at first.

Service-aware on-call

Per-service schedules with follow-the-sun handoffs, overrides, and Google Calendar sync. Engineers only page for systems they own.

Runbook automation

Wire common remediations to one-click actions. Rollback, scale up, drain traffic — without context switching to a terminal at 3am.

Auto-drafted postmortems

Every incident produces a structured timeline you can edit, not write from scratch. Blameless template baked in, action items tracked to closure.

Self-hosted control plane

Run the diagnosis engine inside your own VPC. Incident data never leaves your perimeter. SOC 2 Type II, ISO 27001, GDPR compliant.

Pricing

Pricing that respects engineering budgets.

Per-team pricing, not per-seat. Engineers shouldn't dread inviting their teammates to the on-call rotation.

Customer stories

The teams that stopped dreading their on-call week.

Real engineers, real fragments of real Slack messages.

"We cut MTTR from 38 minutes to 6 over a single quarter. The diagnosis engine pointed at the right commit on the first incident — I haven't manually grepped a deploy log since."

Maya Reyes
STAFF SRE @ FINTECH CO

"Switched from PagerDuty in an afternoon. The migration tool brought in every schedule and escalation policy. Our on-call rotation went from a punishment to something engineers actually volunteered for."

DK
Daniel Kowalski
ENG LEAD @ SERIES B STARTUP

"The first time I got paged and the auto-routed root cause turned out to be correct, I texted my co-founder. The second time, I stopped panicking. The third time, I made coffee first."

PS
Priya Sundaram
FOUNDING ENGINEER @ DEVTOOL CO

"We use the postmortem drafts as our actual postmortems. The timeline, the impact, the action items — already there. We just edit. It saves my Mondays."

Jordan Tran
PLATFORM LEAD @ MARKETPLACE CO

"My team was about to lose two senior engineers to burnout. Six months on Throughline and the rotation finally feels sustainable. Headcount is no longer something we throw at incidents."

Aisha Chen
VP ENGINEERING @ HEALTHTECH CO

"The self-hosted control plane was the deal-breaker. Our compliance team signed off in a week instead of the usual three months. Every other vendor wanted us to ship audit data to their cloud."

Who built this

Built by engineers who lived through too many 3am pages.

Throughline started as an internal tool at a previous job. Then it became a side project. Then it became the only thing we wanted to work on.

Elena Harrow

CO-FOUNDER & CEO

Spent six years at PagerDuty leading the incident intelligence team. Watched too many engineers burn out on rotation. Built the first version of Throughline as a Sunday-afternoon side project to fix it.

FAQ

Questions engineers always ask first.

If yours isn't here, our solutions team usually replies inside 2 hours during business days.

How is Throughline different from PagerDuty or Opsgenie?
Legacy paging tools were built to wake you up. Throughline was built to give you the context you need before you even open your laptop. We auto-correlate alerts, surface the likely root cause, and route to the engineer who last touched the affected service — not just whoever is on rotation.
What does the 90-second root cause claim actually mean?
From the moment an alert fires, Throughline correlates it against recent deploys, infrastructure changes, and historical incident patterns. In 87% of incidents across our customer base, a ranked list of probable causes is surfaced within 90 seconds. You still decide the fix — we just remove the archaeology.
Which observability tools do you integrate with?
Datadog, New Relic, Grafana, Prometheus, Sentry, Honeycomb, CloudWatch, Splunk, and Elastic out of the box. Custom webhooks cover the rest. Setup takes under ten minutes for the major three.
Can we run Throughline on our own infrastructure?
Yes. Enterprise customers can deploy a self-hosted control plane inside their own VPC. The diagnosis engine runs locally, no incident data ever leaves your perimeter. We support AWS, GCP, and on-prem Kubernetes.
How does the on-call rotation work?
Schedules are defined per service, not per team, so engineers only get paged for systems they actually own. Overrides, escalation chains, and follow-the-sun handoffs are configurable. You can sync to and from Google Calendar.
Is Throughline SOC 2 compliant?
SOC 2 Type II, ISO 27001, and GDPR compliant. Our security and audit documentation is available under NDA from the Trust page. Penetration tests are run quarterly by an external firm.
What happens when the trial ends?
Nothing breaks. You drop to the Starter plan (free, up to 3 engineers) and your data stays put. No surprise charges, no card required up front, no sales team chasing your inbox. Upgrade when you're ready.
Can we migrate from PagerDuty without downtime?
Yes. Our migration tool imports schedules, escalation policies, services, and integrations in one click. Most teams run both systems in parallel for a week, then cut over. We provide a dedicated solutions engineer for the first 30 days at no cost.

Stop being on-call alone.

Two-thousand-plus engineering teams already sleep through their rotation week. Yours can be next.
