Coframe announced a $25 million Series A on November 9, co-led by Khosla Ventures and Hanabi Capital. The company says cumulative funding now totals $35 million. These are different figures: the $25 million is the newly announced financing round, while $35 million includes prior capital. No valuation was disclosed in the issuer release.
The San Francisco startup builds a system that generates, tests and optimizes website pages, landing pages and advertising using coordinated AI agents for strategy, design, engineering, quality assurance and analysis. The goal is to shorten the cycle between identifying a potential improvement and deploying a tested variation.
Coframe says its technology has produced more than $300 million of incremental revenue for its customers, with reported conversion improvements at clients including Dropbox and Replit. That $300 million is a company-attributed estimate of customer outcomes, not Coframe's own revenue or the amount raised. Independent auditing of those performance claims was not supplied.
The company also describes work with OpenAI on optimizing advertising and landing pages together, as AI agents increasingly become participants in online discovery and purchasing. The release does not provide financial terms for that collaboration, and planned expansions to apps and email should not be described as completed products.
The funding is a bet that generative models can replace parts of the traditional manual A/B testing and digital optimization workflow. Its importance lies in both the size of the growth-stage investment and the measurable business processes it targets, though customer-level uplift and long-term retention will need continued scrutiny.
