Coframe Raises $25 Million to Tailor Websites for Individual Visitors

Coframe announced a $25 million Series A on Nov. 9 to build software that tailors websites to individual visitors, bringing the San Francisco startup’s total funding to $35 million.

Khosla Ventures and Hanabi Capital co-led the financing. Coframe raised about $9.3 million in a seed round in October 2024. Founded in 2023, the company has about 53 employees. Its founders are CEO Josh Payne and VP of Engineering Pavlo Razumovskyi.

The platform combines specialized transformer models with AI agents that handle work in areas such as strategy, design and data science. It is designed to build and test websites, landing pages and ads, then refine them in a continuing process. The system aims to tailor those materials to individual visitors.

That process differs from traditional A/B testing, in which a team compares two versions of a page, waits for results, chooses one and starts another test. Coframe’s software is designed to keep generating, testing and refining materials on an ongoing basis instead of running tests in occasional campaigns.

Coframe says its platform has generated more than $300 million in incremental revenue for customers. The company also cites conversion increases of 158% at Dropbox, 410% at Replit and 60% at Cash App. Those performance figures are Coframe’s own and have not been independently verified.
