Coframe Raises $35 Million to Build Websites That Rewrite Themselves
Coframe has raised $35 million in total funding, including a $25 million Series A led by Khosla Ventures and Hanabi Capital, to pursue a bold idea: websites, landing pages, and ads should continuously improve themselves instead of waiting for humans to schedule another redesign.
The company calls this vision the “living internet.” Its platform plugs into a business’s website or advertising campaigns and uses AI agents to generate, test, deploy, and refine different versions of digital experiences. Instead of showing every visitor the same fixed webpage, Coframe aims to personalize content and layout while learning which variations create better outcomes.
Coframe says its system includes agents for strategy, design, engineering, quality assurance, and data science. Those agents can produce and test hundreds of variations in minutes. Behind them is a specialized transformer model trained on user interactions, designed to learn from how people move through digital experiences.
The company reports generating more than $300 million in incremental customer revenue. It says Dropbox achieved a 158% conversion-rate increase, Replit saw a 410% increase, and Cash App recorded a 60% lift. Coframe also says one Fortune 500 customer saw a 70% conversion gain within 30 days. These are company-reported metrics, so read them as claims rather than independently verified industry benchmarks.
Still, the underlying concept is worth watching. Traditional A/B testing is often slow, expensive, and limited by the capacity of design, engineering, and marketing teams. If AI can safely create, test, and learn from large numbers of variants, websites could become more adaptive and less static.
There are real questions to solve. How transparent should personalization be? How do brands prevent an optimization system from drifting away from their voice? What happens when a model optimizes for clicks but hurts long-term trust? And how should companies treat visitors who do not want behavior-driven experiences?
