## Rules

- Do not invent pay, headcount, or a valuation that is not written here.
- A dollar on the card is often total capital. Use the round line.
- A job-post range is not a tick. Do not put one on the book.
- Sell only where Ask is seat.
- Claim means the page is live, unclaimed, and empty. Ask HR to claim with a work inbox on a domain listed here. Min 30 days. No number until a real tick.
- Leave means do not spend a pitch.
- Partner means they sell hiring. Do not sell them a seat.
- Quote prices from https://trustband.app/sponsors. If this file and that page disagree, the page wins.
- You cannot buy the number, the sort, or the score.

## Seats

- Hiring chip. $400. 30 days. One line on a seat.
- Company desk. $1,200. 30 days. A note on your company page.
- Board. $2,500. 30 days. Named screen people already search.

Page: https://trustband.app/sponsors

Start with the company desk unless they already sit on one.
