Most A/B testing platforms give you a dashboard and some statistical significance. Coframe gives you an AI that builds the experiments itself.
The San Francisco startup, founded in 2023, is betting that the entire manual workflow for conversion optimization is obsolete. Its core product is an autonomous system that generates variants of websites, landing pages, and ads, runs them against each other, analyzes the results, and deploys the winner. The company calls this a "living internet," where digital experiences adapt continuously rather than remaining static after launch [Business Insider, November 2026].
For CEO Josh Payne, the most compelling proof point isn't just the customer results. It's that Coframe used its own technology to build Coframe. Roughly 80% of the company's own frontend user interface was AI-generated, built with an internal tool called Coffee, according to a company post from December 2023 [Coframe on X, December 2023]. The tool was designed to let developers, or founders who don't know React, build and iterate on UI much faster [Sebastien Lohier - Google DeepMind | LinkedIn, retrieved 2026].
The Autonomous Optimization Wedge
Coframe's wedge is replacing a cross-functional, human-driven process with a closed AI loop. Traditional conversion optimization requires coordination between growth, design, engineering, and analytics teams to ideate, design, build, and test variants. Coframe's platform aims to automate that entire chain, from ideation to analysis [Antler, November 2026].
The system reportedly uses multimodal AI models trained to understand both user behavior and specific business goals. This allows it to generate coherent, on-brand creative and copy variations, not just swap button colors. The platform then manages the traffic routing, gathers performance data, and determines which variant to scale. The stated goal is to turn a weeks-long manual process into a continuous, autonomous optimization engine.
The Team Behind the Bet
The founding team pairs a serial entrepreneur with a technical co-founder experienced in bringing AI to market.
- Josh Payne, Co-founder and CEO. Payne is an AI researcher and entrepreneur with a background in mathematics and computer science from Stanford. He previously co-founded Autograph, the Tom Brady-backed sports and entertainment company, and has been involved with other ventures including AccessBell [Business Insider, November 2026] [Grand Slam Journey podcast, July 2025].
- Pavlo Razumovskyi, Co-founder and VP of Engineering. Razumovskyi brings engineering leadership to the partnership, with prior experience as CTO at InkHunter [Dev Curation, November 2026].
Recruiting materials describe a broader team built from competitive programmers, former founders, and AI researchers who have worked on prominent open-source code-generation projects [Khosla Ventures job listing]. The company is actively hiring for roles in growth engineering, applied science for experimentation, and sales in EMEA, indicating a push to scale both the product and its commercial footprint [Khosla Ventures jobs, November 2026].
Fueling Growth With a $35 Million War Chest
In November 2026, Coframe closed a $25 million Series A round co-led by Khosla Ventures and Hanabi Capital, bringing its total disclosed funding to $35 million [PR Newswire, November 2026]. The round included participation from Antler and notable angels like Nat Friedman, as well as leaders from OpenAI, Anthropic, and Google DeepMind [PR Newswire, November 2026] [Antler, November 2026].
The capital is earmarked for expanding the platform's capabilities and scaling its go-to-market motion. The investor lineup, particularly the involvement of AI lab veterans, signals a belief in the technical ambition behind the "living internet" thesis.
| Round | Amount | Lead Investor(s) | Date |
|---|---|---|---|
| Series A | $25 Million | Khosla Ventures, Hanabi Capital | November 2026 |
| Total Disclosed Funding | $35 Million |
Early Traction and a Major Partnership
The company claims significant early results. According to a November 2026 report, Coframe says it has generated more than $300 million in incremental revenue for its customers [Business Insider, November 2026]. Named customers include Dropbox, Boston Consulting Group (BCG), Block, Backcountry, and Sur La Table [Business Insider, November 2026].
A strategically important partnership is with OpenAI. Coframe is working with the AI giant on its ChatGPT ads offering, with the aim of letting customers optimize an advertisement and its corresponding landing page as a single, continuously learning experience [Unite.AI, retrieved 2026]. This integration could provide a powerful distribution channel, embedding Coframe's autonomous optimization directly into a major AI platform's advertising workflow.
The Technical Breakdown and Scale Risks
The architecture appears to be a pipeline of specialized AI agents. One set of models handles creative generation, understanding brand guidelines and value propositions. Another set manages the experiment orchestration, ensuring statistically valid traffic splits and result collection. A final layer performs the analysis and decision-making to promote winning variants.
The technical risk lies in the complexity of maintaining coherence and brand safety across thousands of autonomously generated variations. At scale, an errant model could produce off-brand messaging or a flawed experiment design that costs a customer real revenue. The platform's reliability isn't just about uptime, it's about the correctness of its autonomous decisions.
Furthermore, the value proposition hinges on the system's ability to outperform skilled human growth teams consistently. If the AI's creative or strategic insights plateau, the product becomes a faster testing tool, not a replacement for the team. The next twelve months will be about proving that the $300 million in attributed revenue is a repeatable pattern, not a collection of early, easily-won gains. Success means moving from a novel experiment to the default engine for digital experience iteration.
