# The glass demo — "Hýalos"

**Hýalos** (ὕαλος, ancient Greek for *glass*) is Thalatta's campaign: **marketing you can see
straight through.** Almost all marketing is done *to* you, in the dark — a profile you never
see, a score you can't read, a decision made before you've said a word. Hýalos turns that
inside out.

If you're a prospect in this campaign you can **open the glass**: sign in with your email and
see *exactly* the record held on you — no more, no less. Ask the assistant why we reached out,
what Thalatta does, and what this is demonstrating. Set your own status — *interested* or *not
interested* — and that's the whole transaction. Nothing about you is hidden from you.

## How it works, in plain terms

1. **You get an email** with a link to your own page.
2. **You sign in with a one-time code** sent to that email — no password, no account to manage.
3. **You see your record** — the handful of fields actually held, and nothing more.
4. **You ask the assistant anything** — why we reached out, what Thalatta does, what this proves.
5. **You set your own status** — interested or not — and every change is written to a plain
   **audit trail** you can read.

The two statuses a prospect can set:
- **Interested** ("please reach out").
- **Not interested** ("please don't contact me") — one click, logged, done. No dark-pattern
  unsubscribe maze.

## Why it's good for everyone

- **For the prospect:** see your own data, correct the record, decide your own status.
  Transparency isn't a courtesy here; it's the product.
- **For the business:** trust is the scarcest thing in outreach. A company confident enough to
  show what it knows — and let you steer it — earns a different kind of attention, and works
  from a cleaner signal (status changes that came straight from the person).
- **For the industry:** every campaign run this way makes "we built a profile you'll never
  see" look like what it is.

## Where it lives

- **thalatta.ai/glass** — the explainer (the belief page).
- **glass.thalatta.ai** — the authenticated per-prospect app (this experience), linked from
  the campaign email.

The glass campaign isn't a gimmick bolted on — it's a small, honest demonstration of how
Thalatta builds AI: give the assistant only what it needs, in the open. You're standing inside
the proof. How that separation is enforced is in [the architecture](architectures.md); the
briefing the assistant reads is [the OKF bundle](about-okf.md) itself.
