Boost is a paid feature on onbrand. One Boost credit places an event or influencer profile at the top of the brand discovery feed for 7 consecutive days. A Boost is bound to an entity — an event or an influencer profile — not to a single proposal, so a Boost on an entity elevates all of that entity's proposals across every brand for the active 7-day window.
A Boost does not guarantee a sponsorship, product sample, partnership, response, reply, or any specific outcome. Brands decide independently whom they partner with.
