Coframe, a startup that uses AI to tailor websites to each visitor, has raised a $25 million Series A co-led by Khosla Ventures and Hanabi Capital. The round brings its total funding to $35 million. The valuation was not disclosed. Founded in 2023 by AI researcher Josh Payne, Coframe aims to turn static sites into what it calls the "living internet." Khosla Ventures also backed the seed round. Vinod Khosla said AI has enabled "extreme customization" and that writing code for every page is too slow and costly. Coframe says it has generated more than $300 million in incremental revenue for customers, including Dropbox, Block, and Sur La Table. It says conversion rates rose 158% at Dropbox, 410% at Replit, and 60% at Cash App.
