Coframe

Static web pages that wait months for a redesign are the target of Coframe's product. It connects to a company's website or advertising campaigns and keeps producing new variations, testing them and deploying the winners, with each visitor able to see a personalised version. Apps and email are on the roadmap. Customers named by the San Francisco business include Dropbox, BCG, Block, Backcountry and Sur La Table.

Five agent roles and a behaviour model

The work is split among AI agents acting as strategist, designer, software engineer, QA specialist and data scientist, which can build and test hundreds of variations in minutes. They rely on a proprietary transformer model of user behaviour, which the company says draws on hundreds of millions of sessions each month. A collaboration with OpenAI covers its ChatGPT ads offering, so that an advert and its landing page can be optimised together.

Claimed results and how they were reached

Coframe reports more than $300 million in incremental revenue for customers and a 39% experiment win rate across thousands of variants, and it publishes conversion rate gains for individual brands. Those are the company's own figures. Its team has grown through the purchase of companies founded by two early Optimizely executives, Bo Mohazzabi and Steven Ebin, who now lead go-to-market and revenue optimisation.
