Sponsor
StockStamper is where conviction goes on the record. Two slots are for sale. The scores never are.
1 callers · 9 calls on the record
Card of the day
- Your brand dealt into every deck for one day: name, one line, one link, marked Sponsored.
- Not a ticker and not votable. Either swipe moves past it and nothing is recorded.
- The placement is the product: every caller handles your card at the exact moment they are making calls.
- The record stays clean. Sponsored cards never appear on the tape, in counts, or on anyone's page.
- One card per day. No exceptions, no second slot.

Headline sponsor
- The tape on every page reads presented by you, for a week.
- Credit on the about page and first right to the daily email when it ships.
- Exactly one headline sponsor at a time. Exclusivity is the product.
- Future weeks are buyable at the current rate. That is the only lock-in there is.

The ratchet
- Rates only move up. Card of the Day steps up $500 after every 10 days sold. Headline steps up $500 with every week sold.
- The current rate is always public, on this page.
- No discounts, no negotiations. The rate is the rate, and buying earlier is always cheaper than buying later.
Never for sale
The tape, the counts, and the calls. Sponsors buy a card in the deck, never a number on the record: sponsored cards cannot be voted on at all, so there is no verdict to buy. Nothing backdated, nothing deleted, nothing bought.
