Synopsis
Anthropic's CFO, Krishna Rao, revealed that over 90% of the company's code is now generated by its AI tool, Claude Code. AI systems are automating significant portions of software engineering, finance, and operations, freeing employees for oversight and strategy. Despite automation, Anthropic is accelerating hiring, viewing AI as a productivity enhancer that amplifies talent.Listen to this article in summarized format
“For us, scaling laws are alive, and we’re seeing that with more releases. Within the company, over 90% of our code is actually written by Claude Code. Models themselves are helping us build the next generation of models,” Rao told O’Shaughnessy on the Invest Like the Best podcast.
Rao described how Anthropic is deploying its AI systems, including Claude and Claude Code, to automate large parts of software engineering, finance, and enterprise operations. He said the finance team uses a library of more than 70 specialised AI workflows to handle tasks such as statutory financial statements and monthly reviews.
Reports that previously took hours — including weekly revenue and compute utilisation reports — can now be completed in about 30 minutes, he said.
According to Rao, Anthropic’s finance outputs are often 90–95% complete before human review. Employees are increasingly focused on oversight, judgement, and strategy, while AI handles much of the execution layer of knowledge work.
“Everyone kind of becomes a manager,” he said, describing teams supervising fleets of AI agents working simultaneously across projects.
Despite these automation gains, Rao said the company is not reducing headcount. Instead, hiring has accelerated alongside an expansion in the scale of work teams can handle.
He described AI as a productivity accelerant that amplifies talent rather than replacing it. The company continues to prioritise talent density, maintaining relatively lean teams of highly skilled workers empowered by AI tools.
“We’ve been able to hire great people, but AI has made even those incredibly talented people more productive. We’ve actually hired a lot more people because there is no shortage of work to do. I see it as an accelerant to productivity — even as we grow the team, people become more productive as they use Claude within the company,” Rao added.
Anthropic has raised approximately $75 billion since Rao joined, along with an additional $50 billion in commitments tied to partnerships with Amazon and Google. The company’s annualised revenue run rate reportedly grew from around $9 billion at the beginning of the year to more than $30 billion by the end of the first quarter.
