# MediaPact

> MediaPact is a two-sided marketplace for buying and selling flat-fee paid media — newsletter sponsorships, sponsored content, and direct media placements. Brand marketers and agencies use it to discover and purchase publisher inventory without email chains, custom contracts, or manual invoicing. Publishers list inventory once and receive inbound demand from vetted buyers. Free for buyers; sellers pay a commission on completed transactions.
