Each sequence starts with the next Arena company by capital rank, followed by up to two profiles in a daily rotation independent of capital. A profile qualifies for rotation when it includes a story, the problem solved, its target audience and current verified domain control. Domain proof confirms control of the website, not revenue or company quality; revoked or expired proof removes rotation eligibility. We remove duplicates, then continue the same sequence across pages. Filters apply before ordering. Every company is published; this is discovery placement, not an endorsement or an extra ranking. The rotation changes at midnight UTC.
