Capabilities
Built for PMMs at high-velocity companies
Hummingbird monitors production UI changes, captures product visuals and visual diffs, and turns every Hum into a proof-backed story you can share across Marketing, Docs, and Sales. Request a workspace invite in Run Hum or review per-Feather pricing when you're ready to scale.
Evidence-linked Feathers
Each Hum includes Feathers with product visuals and visual diffs captured from the live UI, so Marketing, Docs, and Sales share the same proof.
Story Impact Score Ranking
The dashboard ranks Hums by Story Impact Score so you know what to publish first, and per-Feather usage shows what you captured.
Slack review cards + Review Chips
Slack review cards carry the evidence-linked bundle, and Review Chips suggest who to loop in, so review happens without chasing stakeholders.
Time-to-Publish Under 2 Minutes
Start humming → publish-ready bundle in under two minutes, so you can share the truth while the release is still fresh.
Rollback Adjacent (≤10 s)
Publish creates a stable, evidence-linked bundle, and rollback stays adjacent, so you can share with confidence.
The PMM Experience
Product Marketing Manager Workflow
At the start of my day, I get a Hummingbird alert that the product team pushed to production overnight. AI-generated highlights make the live changes obvious, and by the time my coffee cools the release story draft from real product visuals and visual diffs is ready. I tweak a few lines, promote the run to baseline, and click Publish. Everything is live in under two minutes.
