Coframe raises $25m Series A to let AI rewrite websites as people use them

9 November 2026: Coframe says it has raised $35 million in total funding, including a $25 million Series A co-led by Khosla Ventures and Hanabi Capital, for software that generates, tests and deploys new versions of websites, landing pages and adverts without waiting for a redesign. Leaders at OpenAI, Anthropic and Google DeepMind also took part, the company says.

Not yet independently verified. The release was read on PR Newswire because we found no copy on Coframe's own site. The revenue and conversion figures are the company's own, and it does not say what the new money will be spent on. We will update this when it can be confirmed, and remove this note.

Agents in place of the experiment backlog

Coframe plugs into a company's site or campaigns and runs a team of AI agents acting as strategist, designer, software engineer, QA specialist and data scientist. They produce and test hundreds of variations and personalise what each visitor sees, using a transformer model trained on user interactions across what the company describes as hundreds of millions of sessions a month. Apps and email are next on its roadmap.

"Coframe is building the living internet, where two people can visit the same website and have completely different experiences," said Vinod Khosla, founder of Khosla Ventures, who called it a leap beyond traditional A/B testing.

The company's own results

Coframe says it has generated more than $300 million in incremental revenue for customers. It cites conversion rate increases of 158% for Dropbox, 410% for Replit and 60% for Cash App, and a 70% lift within 30 days of contract signature for one unnamed Fortune 500 customer. Across its base, which also includes BCG, Block, Backcountry and Sur La Table, it puts the average conversion improvement above 20%.

The experiment figure is the one a testing team will want to question. Coframe claims a 39% win rate across thousands of variants, more than three times the industry average, and says one Dropbox experiment that previously took four weeks of engineering, design and QA was built and deployed in 30 minutes. A buyer should ask how "win" is defined and which statistical threshold applies, because a system running hundreds of variations at once faces a much greater risk of false positives than a team running a few.

From Autograph to a Series A

Josh Payne, the chief executive, founded Coframe in 2023 after studying mathematics and computer science at Stanford. He previously co-founded Autograph with Tom Brady, which the release says reached a valuation of more than $2 billion. Pavlo Razumovskyi is co-founder and vice president of engineering.

Coframe has also bought companies founded by two early Optimizely executives, Bo Mohazzabi, now vice president of go-to-market, and Steven Ebin, now general manager of revenue optimisation. Earlier backers named in the release include Nat Friedman and Antler.

The company is working with OpenAI on its ChatGPT ads offering, so that customers can optimise the advert and the landing page together.

Our A/B testing software category lists eleven products.
