The Startup Guide to Incident Response: What to Set Up Before Your First Outage

You Will Have an Outage

Every startup ships fast. That's the point — speed is your competitive advantage. But shipping fast means cutting corners on infrastructure, deferring monitoring, and hoping that your MVP holds together long enough to find product-market fit.

Then one day your app goes down. Maybe it's a database migration that locks a table. Maybe it's a third-party API that stops responding. Maybe it's a null pointer exception in a code path nobody tested.

The outage itself isn't the problem. How your team responds to it is. And if you haven't set anything up before it happens, you'll spend the first 30 minutes of the outage figuring out the process instead of fixing the issue.

Here's what to set up before your first outage. It takes about an hour.

The Four Things Every Startup Needs

You don't need a 50-page incident response playbook. You don't need a dedicated SRE team. You don't need enterprise monitoring with 500 dashboards. You need four things:

1. Monitoring — Know when something breaks before your users tell you
2. On-call — Know who's responsible for responding right now
3. Notifications — Reach the responsible person reliably
4. Tracking — Record what happened so you learn from it

That's it. These four capabilities cover 90% of incident response for teams under 50 people.

Step 1: Monitoring (15 Minutes)

Start with uptime monitoring for your most critical endpoints. You can add application performance monitoring, log analysis, and distributed tracing later. Right now, you need to know when your app is unreachable.

What to monitor first:

Four monitors. That's your starting point.

Configuration recommendations for startups:

• Interval: 60 seconds for most endpoints, 30 seconds for payment flows
• Failure threshold: 3 consecutive failures (prevents false positives from transient issues)
• Grace period: 60 seconds (prevents alert flapping during deployments)

You can add more monitors as you identify critical paths. But these four will catch the outages that matter most.

Step 2: On-Call (10 Minutes)

If your team is 2-5 engineers, your on-call setup is simple: a rotation where everyone takes turns being the primary responder.

For a 3-person team:

• Weekly rotation: Alice (week 1) → Bob (week 2) → Charlie (week 3) → repeat
• Handoff time: Monday 10 AM (gives the incoming on-call time to settle in)
• Backup: The next person in the rotation is the secondary

For a 2-person team:

• Weekly rotation: Alice (week 1) → Bob (week 2) → repeat
• Backup: The other co-founder/engineer
• Consider: Alternating 3-4 day shifts instead of full weeks to prevent burnout

For a solo founder:

• You're always on-call (sorry)
• Set up monitoring and notifications so you know about issues fast
• When you hire your first engineer, set up a rotation immediately

The important thing isn't the rotation structure — it's that at any given moment, one specific person knows they're responsible. "Everyone is on-call" means nobody is on-call.

Step 3: Notifications (15 Minutes)

You need two notification channels: one for during-work-hours and one for wake-me-up-at-3-AM.

During work hours:

• Slack DM to the on-call engineer
• This is sufficient for issues detected during business hours when the engineer is at their computer

After hours:

• SMS to the on-call engineer's phone
• Phone call if no acknowledgment within 5 minutes
• SMS to the secondary on-call if no acknowledgment within 10 minutes

Don't overcomplicate this. At an early stage, two escalation steps are enough:

1. Notify the primary on-call via Slack DM (always) + SMS (if after hours)
2. If no response in 5-10 minutes, escalate to the secondary

You can add quiet hours, severity-based routing, and WhatsApp as your team grows. Right now, you need a reliable way to reach one person.

Step 4: Tracking (20 Minutes)

When an incident is resolved, you need a record of what happened. This doesn't need to be elaborate — you just need enough information to learn from the experience.

At minimum, track:

• What went wrong (1-2 sentences)
• When it started and when it was resolved
• What fixed it
• What you'll do to prevent it next time (1-2 action items)

Use your incident management tool's built-in tracking rather than a separate document. When the alert is in the same system as the tracking, you get an automatic timeline of detection, acknowledgment, and resolution.

The One-Hour Setup Guide

Here's the complete sequence, assuming you're starting from zero:

Minutes 0-5: Create your account and team Sign up for an incident management platform. Create your team and invite your co-founder or engineers.

Minutes 5-15: Set up monitors Add uptime monitors for your 3-4 critical endpoints. Use the recommended configurations above.

Minutes 15-25: Configure on-call rotation Create a weekly rotation with your team. Set the handoff time to a morning slot during business hours.

Minutes 25-40: Set up notifications Connect Slack for during-hours notifications. Add phone numbers for after-hours SMS and phone calls. Configure a two-step escalation: primary on-call, then secondary.

Minutes 40-50: Test the setup Trigger a test alert and verify it reaches the on-call engineer through the correct channels. Verify the escalation path works by not acknowledging the test alert and confirming the secondary gets notified.

Minutes 50-60: Document the basics Write a short message in your team Slack channel: who's on-call this week, what the escalation path is, and how to acknowledge alerts. This is your incident response documentation for now.

When to Add Complexity

Your one-hour setup will serve you well for months. Here's when to add more:

When you hit 5-10 engineers: Add severity levels to your alerts. Not every monitor failure is critical — start differentiating between "app is completely down" and "one endpoint is slow."

When you get Slack integration: Add Slack channel listeners to catch issues reported by team members before monitoring detects them.

When you have your first repeat incident: Set up a simple post-mortem process. Attach a root cause analysis to the incident and track the action items.

When you have 10+ monitors: Add webhook integrations from your other tools (error tracking, CI/CD, custom scripts) to centralize alerts.

When you have a distributed team: Add timezone-aware scheduling and consider follow-the-sun rotations.

When alert volume increases: Add alert grouping, quiet hours, and webhook filtering to reduce noise.

When you hit 15+ engineers: Add PTO-aware scheduling so the on-call rotation automatically adjusts for vacation.

What Not to Do

Common mistakes startups make with incident response:

Don't skip monitoring because "we'll just watch the logs." You won't. And when something breaks at 2 AM, nobody is watching anything.

Don't use a shared on-call phone. It gets left on someone's desk. Use a rotation with individual phone numbers.

Don't build your own monitoring. A cron job that curls your endpoint and sends a Slack message is not monitoring. It has no escalation, no acknowledgment tracking, no history, and it breaks silently.

Don't wait until after your first major outage. The worst time to set up incident response is during an incident. It takes an hour now or several hours during a crisis.

Don't over-engineer it. You don't need runbooks for every possible failure mode. You need to know when something breaks and how to reach the person who can fix it.

Start Simple, Scale Later

OpShift is designed for teams that want to start simple and add complexity as they grow. The initial setup takes minutes: add monitors, create a rotation, configure notifications. As your team grows, add Slack listeners, webhook integrations, PTO management, alert grouping, and multi-channel escalation.

Pricing starts at $14/month for up to 50 users — enough for most startups through Series B and beyond. No per-seat pricing, so adding every engineer (and your PM, and your support lead, and your CTO) costs nothing extra. Get started at opshift.io.
