Promi

Promi is an AI-powered discount personalization platform built for e-commerce merchants. It uses machine learning to predict shopper price sensitivity at the individual level and dynamically adjusts discount depth in real time—by product, traffic source, and customer segment—to protect margin while maximizing revenue. Merchants use Promi to run smarter clearance sales, personalize email campaign discounts, and display price strikethroughs site-wide, with built-in A/B testing to measure impact on revenue, gross profit, and conversion rate. Backed by Y Combinator (S24) and built by alumni from Uber and Google.
