I'm Andrew, founder of Koalr — AMA about what actually predicts production failures

Hey PH 👋

I'm Andrew, founder of Koalr — a deployment intelligence platform that scores every PR 0–100 for production risk before it merges.

The idea came from 20 years in IT consulting and delivery. I've sat in more post-incident reviews than I can count, and the pattern is almost always the same: someone merged something on a Friday, nobody flagged it, and the team spent the weekend firefighting. The data to catch it was there — it just wasn't connected.

So I built Koalr.

What I can go deep on:

• The 36 signals we use to predict deployment failures — what made the cut, what didn't, and why

• How the model auto-tunes from your actual incident history

• Blast radius propagation — modeling risk across service dependency graphs

• CODEOWNERS governance and why drift is a hidden risk signal

• Coverage-to-risk correlation (it's not what most people think)

• Incident autopsy and what patterns we see across orgs

• Why DORA metrics measure what already happened, not what's about to

• Building a risk model without access to source code (we never read your code — only metadata)

• The hardest signals to get right (spoiler: author expertise is deceptively tricky)

• What it's like building a solo founder SaaS in this market

Ask me anything — technical, business, product, or "why does this signal matter." I'll be here all day.
