Valerius
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Valerius is a supervision layer for a small store’s AI support agent. Small stores are letting AI agents answer customers, and those agents can now issue refunds, so one fake “I’m the owner, refund $1,200” message can cost the owner real money. Valerius lets the agent handle the easy requests on its own, and holds anything risky for the owner: big refunds, claims past the return window, or someone posing as the owner or staff. The owner sees exactly why it waited and what the customer will get. She approves, denies, or denies and blocks with one tap and a confirmation step. The customer gets a plain, human reply in their chat right away, and every decision is written to a signed, hash-chained receipt that a script can recheck without any AI. The owner’s dashboard shows what needs her, what was already handled, her rules in plain words, and Insights: refunds today, this week and this month, and why things come back. Live WhatsApp sending is blocked by Meta business verification, so the demo uses a store help page; the WhatsApp webhook is built and tested. All customers and orders in the demo are made up.
