Rainmaker (now marketed under the product names "Guestrev" and "Grouprev") is a cloud-based revenue management platform for hotels, resorts and casinos, acquired by Cendyn in 2019. The software uses statistical models and machine learning to forecast demand and generate dynamic pricing recommendations by room category and market segment. It is delivered as SaaS and synchronizes in real time with property management systems (PMS) and channel managers to automate rate updates. Pricing is customized based on room count, integrations and Cendyn products purchased, and is not publicly listed.
