Coframe Raises $25 Million Series A for Autonomous Web Tools

By Amara Osei

Coframe has raised $35 million in total funding, including a $25 million Series A co-led by Khosla Ventures and Hanabi Capital. The round also included participation from executives and technology leaders associated with OpenAI, Anthropic and Google DeepMind, Coframe said.

Coframe will use the money to expand an autonomous AI platform that continuously generates, tests and improves websites, landing pages and advertising campaigns. Coframe said the system automates work now handled through scheduled design, engineering and marketing projects.

How does Coframe's autonomous platform work?

Coframe contrasts its system with traditional websites, which generally display predetermined content until development teams change them through scheduled projects. The company said its platform automates much of that process by generating new content and design variations, testing their performance and deploying improvements.

Coframe uses a specialized transformer model trained on user behavior. AI agents divide the work into roles resembling a strategist, designer, software engineer, quality assurance specialist and data scientist.

Together, the agents can generate and evaluate hundreds of website or advertising variations within minutes, Coframe said. The model analyzes visitor interactions, improves future versions and personalizes content for different visitors while adjusting interfaces toward conversion and engagement objectives.

Payne describes the model as the “living internet,” in which websites and other digital interfaces adapt continuously to user interactions and business objectives.

“We’re building an internet that improves itself. A digital experience should understand what it is trying to accomplish, adapt to the person interacting with it and learn from every result. Instead of waiting months for the next redesign, companies should have websites and applications that get better every day.”

Khosla said Coframe is moving beyond conventional A/B testing toward interfaces that change for each visitor.

“For decades, the web has been frozen in place, showing every visitor essentially the same page. Coframe is building the living internet, where two people can visit the same website and have completely different experiences, personalized to who they are and what they need.”

“These interfaces continuously learn and improve themselves. This is a huge leap beyond traditional A/B testing and the next iteration of the internet.”

What results has Coframe reported?

Coframe says its technology has generated more than $300 million in incremental revenue for customers. The company lists Dropbox, Boston Consulting Group, Block, Backcountry, Sur La Table and other businesses as customers.

Coframe reported the following results:

• Dropbox: a 158% increase in conversion rate.
• Replit: a 410% increase in conversion rate.
• Cash App: a 60% increase in conversion rate.
• Fortune 500 customer: a 70% increase in conversion within 30 days of signing the contract.
• Customer base: an average conversion-rate improvement of more than 20%.

These are company-reported results and may vary across different implementations and customer environments, Coframe said. At Dropbox, the company said the platform created and deployed in 30 minutes an experiment that previously required approximately four weeks of engineering, design and quality assurance work.

Coframe also reported a 39% experiment success rate across thousands of tested variations. The company said the rate was more than three times the industry average, while customers have increased their experimentation frequency by tenfold or more.

Razumovskyi said the company expects self-improving interfaces to become standard rather than remain an extension of current website management.

“The way most companies build and manage their user interfaces today is wrong, and in a year or two it will be obvious why that is. User interfaces should improve themselves, and be personalized to every user.”

Where is Coframe heading next?

Coframe is developing capabilities for applications, email and other digital experiences beyond website and advertising optimization. The company is also preparing for an internet in which AI agents conduct research, compare products and make purchases for users.

Coframe announced a collaboration with OpenAI involving OpenAI's ChatGPT advertising offering. According to Coframe, the collaboration will help customers optimize advertisements and landing pages as a connected experience. It builds on an earlier partnership that trained a specialized model to generate brand-aligned code and creative assets, Coframe said.

Coframe is also incorporating AI-agent considerations into the websites it builds. According to Coframe, Josh Payne founded the company in 2023 after studying Mathematics and Computer Science at Stanford University. Payne previously co-founded Autograph with Tom Brady, a business that reached a valuation exceeding $2 billion, Coframe said. He also developed GPT-Migrate, described as an early autonomous coding agent.

Coframe has expanded its leadership through acquisitions of companies founded by two former Optimizely executives. Bo Mohazzabi now serves as Vice President of Go-to-Market, while Steven Ebin serves as General Manager of Revenue Optimization.

The Series A proceeds will support more sophisticated AI systems for digital experience creation and optimization, Coframe said. The company aims to combine autonomous software development, design, analytics and personalization, shorten the time needed to improve digital experiences and help clients increase conversion rates and revenue.

As Coframe expands into applications, email and agent-led commerce, its next test is whether its reported gains can hold across the customer environments it says can change outcomes.
