Yieldify *

Yieldify is a website personalization and conversion rate optimization (CRO) platform for ecommerce brands, founded in 2013 in London by Jay Radia and backed by investors including GV (Google Ventures). Its SaaS platform delivers targeted on-site messaging, customer-journey personalization, and A/B testing to lift conversion and revenue. Yieldify was acquired by Publicis Groupe in January 2023 and folded into Epsilon, where it is now offered as the "Accelerate" (Yieldify) platform; yieldify.com now redirects to Epsilon. The product is delivered as a hosted, managed marketing service with a customer help center rather than a public developer API — no public REST/OpenAPI surface, SDK, or developer portal was found during enrichment.
