Description
About Hazel
Hazel is the AI coworker for consumer brands.
We connect to a brand's live data — Shopify, Klaviyo, Amazon, Meta, and dozens of others — and turn it into a teammate operators talk to every day.
Ask "why did repeat purchase rate drop last week?" and 10 seconds later you get an answer, cited from live data.
Hazel also takes action herself, proactively flagging issues and making changes directly in Shopify and the other systems she connects to, on the way to running full playbooks autonomously.
We've raised more than $2M, are rapidly scaling, and serve some of the biggest consumer brands including Bogg Bag, Ultra, and OneSkin.
