The vision, detailed by **CFO Sarah Friar** in a recent essay, moves beyond mere efficiency gains to a fundamental redesign of how finance teams work, decide, and drive business strategy.\n\nFriar, who joined **OpenAI** two years ago, inherited a small finance team scrambling to keep pace with the company’s explosive growth. The manual grind of closing books and refreshing forecasts was a familiar pain point, even with access to the world’s most advanced AI. The solution was not just deploying tools, but reimagining workflows from source data to decision.\n\nThe zero-day close aims to give leaders a real-time, reconciled, and traceable view of the company’s financial position. Continuous forecasting builds on that, showing how the business is changing, what could happen next, and which decisions could alter the outcome. Both are works in progress, but they have already shifted the team’s operating model away from static spreadsheets and manual data hunts.\n\n## The Hackathon That Turned AI Abstract to Action\n\nOne of the first moves was broad access paired with structured experimentation. Friar’s team ran a finance hackathon, bringing in sales engineers to help staff build custom **GPTs** for real problems. The result was **IR-GPT**, a tool grounded in approved investor relations materials that can draft diligence responses in seconds.\n\n**“The hackathon turned AI from an abstract capability into a working tool. In a single day, people could identify a recurring task, build a solution, test it with colleagues, and improve it,”** Friar wrote.\n\nThis bottom-up experimentation, she argues, must be married with top-down strategy. Secure, capable AI in the hands of those closest to the work surfaces practical ideas, while leadership focuses resources on the changes that matter most. The sweet spot is when frontline insights align with major business priorities.\n\nThat principle extends to the core of finance work. Friar describes how AI changes the unit of work by redesigning the full path from source data to decision. For the close, that means connecting approved spending plans, general-ledger actuals, purchase orders, accruals, and transaction details in a continuously reconciled view. AI can prepare initial variance explanations and flag exceptions, but finance validates the numbers and owns the final sign-off.\n\n**“The close does not disappear. What begins to disappear is the scramble to reconstruct the business after the period ends,”** she noted.\n\n## From Spreadsheet Jockeys to Tool Builders\n\nA deeper transformation is underway: finance professionals are becoming builders. Friar cites **OpenAI** research showing that **40%** of finance professionals’ specialized AI use involves work outside traditional finance, and **22%** involves engineering-related tasks. Her team uses **ChatGPT Work** and **Codex** to create custom dashboards that sit atop the business’s full data context, updating as information changes.\n\nOne teammate supporting the advertising business, who had never coded, used **Codex** to build a tool that turns monthly ad forecasts into weekly and daily plans, accounting for weekdays and holidays. It keeps every number tied to the approved model and lets marketing leaders see what changed and where to invest.\n\n**“The people who understand the problem can now shape the solution. Building these tools also prompts them to reconsider the usual way of doing the job,”** Friar explained.\n\nBut autonomy requires guardrails. **IR-GPT** taught the team that AI can accelerate work while humans own the result. The investor relations team still reads drafts, adds judgment, and ensures consistency. Friar advises CFOs to work with IT and governance teams to define data access, permissible actions, approval thresholds, and escalation paths. Every output should connect to a reliable source, and every forecast should carry a clear explanation.\n\nThe brief craze of “tokenmaxxing” has faded, she notes, making it straightforward to set usage limits, budget controls, role-based access, and model-routing rules. Clear accountability builds the confidence to move faster.\n\nMeasuring ROI demands a scorecard grounded in operating performance, not just seat counts or token usage. For each workflow, Friar suggests asking: **What useful work was completed? What quality level was achieved? What was the total cost? Could a different model or approach produce a better outcome for less?** For the close, metrics might include cycle time, share of transactions reconciled automatically, and exceptions requiring review. For forecasting, accuracy, refresh frequency, and decision quality.\n\nThe cheapest model isn’t always the most economical if a better one gets to a reliable answer with fewer attempts and less review. Finance sits at the center of strategy, capital, data, risk, and performance, giving CFOs a unique mandate to lead AI transformation. Friar’s vision is a finance team that understands what is happening as it happens, shows leaders what could happen next, and helps the company make better decisions sooner.
