How order works. Matched companies are the full live catalog slice for this primary category, sorted alphabetically by name. This is not a scored quality ranking. When listing fees open, they are intended to affect publish timing or review-queue position only, not alphabetical order or praise on this page (payments are currently closed). Aevral is a disclosed house listing under the same rules (coming soon, no pin). See /transparency.
