ABOUT
We watched our best engineers become walking encyclopedias
And then we watched them leave — taking years of context with them.
After leading engineering teams at fast-growing startups, we saw the same pattern: senior engineers spent more time answering questions than writing code. They were the single source of truth for architectural decisions, system quirks, and the thousand small choices that accumulate over years.
When key people left, we lost years of context overnight. New hires took weeks to get productive. Incidents took longer because runbooks were outdated or missing entirely. The knowledge had lived in people's heads, not in any system.
We tried wikis, Notion, Confluence — nothing stuck. Engineers don't leave Slack to document things. They're busy. The tool that asks them to change behavior doesn't get used.
So we built engineer9 to capture knowledge where it already lives: in the conversations your team is already having. No new habits. No new tools. Just better memory.

VALUES
What we believe
Knowledge should outlast individuals
Every engineer carries context that the team depends on. When they leave, that context shouldn't leave with them.
Documentation should be automatic
Engineers document in Slack because it's where they work. We capture knowledge there instead of asking people to change their habits.
Trust requires transparency
We always cite our sources. We never train on your data. Your team's knowledge stays yours.
Simple tools for complex problems
@mention and ask. That's the entire interface. The complexity is our problem, not yours.
We're hiring
We're a small team building something engineers genuinely need. If that sounds interesting, we'd love to hear from you.
