OpenAI's CFO says not knowing AI tools like Codex is now a dealbreaker in finance hiring. She put it exactly as bluntly as that.

Speaking at the Liquidity Summit 2026 earlier this month, Sarah Friar said: "I would never hire a finance person who didn't know how to use Excel, and I probably wouldn't hire a finance person today that doesn't know how to use a tool like Codex." Codex is OpenAI's AI coding agent that executes software and technical tasks through natural-language prompts. The analogy to Excel is deliberate and worth taking seriously. Excel wasn't optional for finance professionals in 2005. Codex, or something like it, won't be optional in 2027.

What makes Friar's comment interesting is the specific tool she chose. Codex is not a finance tool. It is a software automation agent. The fact that OpenAI's CFO expects finance hires to know it tells you something about how the boundary between "finance skills" and "technical skills" is dissolving inside AI-native companies. The finance professionals who will thrive in these environments are the ones who can think in workflows, not just in spreadsheets.

Deloitte's Finance Trends 2026 survey of more than 1,300 global finance leaders found that AI and automation skills are now the top priority for developing and sourcing new finance talent, ranking ahead of traditional competencies like regulatory compliance and cost management. That is a significant inversion. The skills that defined a strong finance hire for the last two decades are now table stakes. The skills that were once considered adjacent, technical fluency, workflow automation, comfort with AI-generated outputs, are now what separates candidates.

CFO Connect's State of AI in Finance 2026 report adds the uncomfortable operational context: only 17% of finance teams are actively using AI in core workflows, and few finance professionals have been formally trained in prompting, workflow automation, or model validation. So the bar Friar is describing is being set at the top of the market while most finance functions are still figuring out where to start. That gap is closing faster than most finance leaders think.

The practical implication for any CFO building or hiring a team right now is straightforward. Your next finance hire should be evaluated on AI fluency as a baseline, not a bonus. And the people already on your team need a real development path toward it, not a webinar. The companies that build this capability internally over the next 18 months will have a structural advantage in the talent market. The ones that wait will be hiring into a much more competitive and expensive pool.
