Understanding both platforms
AI-powered integrated business planning and supply chain platform
o9 Solutions is an enterprise-scale AI platform that integrates demand planning, supply chain optimization, and business planning into a unified environment. Its Enterprise Knowledge Graph connects data across divisions to power AI-driven decision-making at large organizations.
For apparel brands, o9 can deliver powerful demand sensing and scenario planning — but it requires significant data science resources, large datasets to train AI models effectively, and a 12–18 month implementation with a consulting partner.
Large enterprises ($500M+) seeking AI-driven demand planning and integrated business planning across multiple divisions
Purpose-built apparel merchandising planning platform
RetailNorthstar is designed specifically for apparel merchandising teams. OTB planning, assortment planning, buy planning, buy execution, and allocation optimization are native workflows — not modules on top of a horizontal AI platform.
AI recommendations are embedded directly into the merchandising workflow — no data science team required. Apparel-specific capabilities like size curves, seasonal OTB structure, and collection-based assortment are built in. Teams onboard in 2–4 weeks.
