See every featurePricing optimization is complicated, but with intelligent price testing you can really boost your profits. Curvature makes price testing easy. You run simple before-and-after price tests, not messy A/B tests, and the AI does the analysis ensuring you compare "apples to apples". The Curvature AI Copilot helps you decide what to test and how by making experiment recommendations.
Blanket discount codes give away margin to shoppers who would have paid more, and you can't negotiate with every visitor yourself. Flux adds an AI agent to your product pages. When a shopper hesitates, it invites them to talk price, then negotiates in real time in your brand voice, never below the hidden price floor you set. Offers under your floor are saved for you to approve or decline.
