Replit, an AI coding platform popular with startup founders and developers, will no longer partner with Anthropic, company CEO and co-founder Amjad Massad said on stage at TechCrunch Disrupt on Thursday.
Massad said the decision was made for a variety of reasons, including cost. Replit announced a partnership with OpenAI in August, but there was no indication that the partnership with Anthropic would end.
“I think ChatGPT is better now,” Massad said, adding that the company uses internal benchmarks to evaluate performance and other metrics. “We also publish public benchmarks, and Sol and Astra consistently show superior performance when building vibe-coded applications from scratch. This was a decision based on both cost, partnership, and performance. For all of these reasons, we felt they were the better partner so far.”
Replit sells a cloud-based software development platform that allows users to develop and deploy apps directly from within their browser. In partnership with Anthropic, Replit used AI Labs’ Claude model to run the platform. This partnership is said to have significantly increased the company’s revenue.
But Massad’s comments were rejected by insiders familiar with Anthropic’s partnership with Replit. One person familiar with the matter, who asked not to be identified, said the partnership is still ongoing.
There is evidence on the company’s website, blog posts, and social media posts that Replit was using Anthropic products as recently as a few weeks ago. For example, a blog post from late September cited Anthropic’s Claude Fable 5 and Claude Fable 5.1 as models running in Replit Agent’s production environment. Around the same time, one of Replit’s product reps posted on X about using Anthropic’s flagship model Opus 5.5 and promoting its features.
TechCrunch has reached out to Replit again for clarification and will update this article if we hear back.
Massad shared insights about the company’s growth on the Disrupt stage, noting that Enterprise is starting to deliver greater revenue.
“We haven’t shared the ARR numbers yet, but from a growth perspective, enterprise was around 2% of our revenue last year,” Massad said. “This year, I think 15% of our revenue will be corporate contracts and over 50% of our revenue will be B2B.”
Massad also commented on the need for better AI safety measures.
“Just as we humans need a certain environment to work, we need a nice office, maybe good food in the office, air conditioning, a computer. Agents also need a habitat to exist and do good work,” he said. “So that habitat has the right orchestration, the right error recovery, the right safety and security and sandboxing, the right networking, the right identity and authentication. And once you understand all of that, you can deploy AI securely.”
