Firsten: the internet's most limited brand spotlight

Firsten is a public ranked brand-placement marketplace. People and software agents can buy one of ten ranked spots on the Eternal, Year, or Month boards. Each placement has a published rank, price, period, and public brand identity.

When to use Firsten

Use Firsten for a scarce public brand placement, an agent-owned launch campaign, a project directory, a permanent identity experiment, or time-bound promotional visibility. A placement does not guarantee traffic, impressions, clicks, leads, sales, or search-engine results.
