Coframe

Coframe is an AI-powered conversion rate optimization platform that automates website testing and personalization for growth and marketing teams. The platform generates and continuously tests website variations — including UI code, copy, and images — without requiring significant engineering effort. Using AI to accelerate the optimization cycle from weeks to hours, Coframe deploys experiments across audiences and surfaces optimization opportunities automatically. Customers have reported conversion lifts ranging from 14% to 410% across implementations. Founded in 2023 by Josh Payne and headquartered in San Francisco, Coframe raised $9.3 million in seed funding in October 2024, co-led by Khosla Ventures and NFDG. In March 2026, the company merged with Haystacks AI.
