Key Insight for Auctor
Enterprise and mid-market companies increasingly use multiple CMS platforms simultaneously (e.g., AEM for corporate site + Contentful for marketing + Shopify for commerce). A content operations platform that can push to and pull from all of these is the missing layer. Prioritize Tier 1 adapters to cover the widest enterprise footprint, then expand into Tier 2 headless platforms where adoption is accelerating fastest.
