Coframe Secures $35 Million to Build a Self-Improving Digital Experience Platform

Coframe announced a $35 million funding round to accelerate its vision of a self-optimizing internet. The round comprises a $25 million Series A led by Khosla Ventures and Hanabi Capital, with participation from executives and researchers across OpenAI, Anthropic, and Google DeepMind. The company targets the next generation of websites, landing pages, and ads that continuously generate, test, and refine themselves.

Coframe’s approach centers on a dedicated transformer model trained on user interactions and a team of AI agents—a strategist, designer, software engineer, QA specialist, and data scientist—that can ideate, build, test, and optimize hundreds of variations in minutes. Since inception, Coframe has helped clients generate more than $300 million in incremental revenue and delivered notable performance gains, including 158% conversion improvements for Dropbox, 410% for Replit, and 60% for Cash App. In a notable engagement with a Fortune 500 client, dozens of variations were launched, yielding a 70% lift in conversions within 30 days of contract signing.

Across its user base, which includes Dropbox, BCG, Block, Backcountry, and Sur La Table, the average conversion uplift exceeds 20%. At Dropbox, a process that previously required four weeks of engineering and QA was executed in about 30 minutes using Coframe, with thousands of variants achieving a 39% win rate—more than three times the industry average—while accelerating testing velocity by tenfold or more. CEO and founder Josh Payne frames Coframe’s objective as building an internet that learns and improves on its own, delivering personalized experiences for each visitor in real time. He envisions a future where websites and apps adapt to individual goals and contexts, rather than presenting the same page to every user. Co-founded by Payne in 2023 after studying at Stanford, Coframe has roots in AI ventures, including the creation of an autonomous coding agent and early work with GPT-based migrations. The company has also acquired teams from Optimizely, integrating their expertise into Coframe’s go-to-market and revenue optimization efforts.

Coframe’s technology hinges on a proprietary foundation model of user behavior—a custom transformer trained on hundreds of millions of sessions each month—to ensure each experiment informs the next. The firm’s broader aim includes supporting a future where more web traffic is driven by AI agents that can research, compare, and purchase on people’s behalf. The collaboration with OpenAI on ChatGPT ads exemplifies this direction, enabling continuous optimization of ads and landing pages as a unified learning process. Coframe is supported by a roster of prominent investors including Nat Friedman, Antler, and other leading technology backers. More information is available at coframe.com.
