Friar, who joined OpenAI two years ago, said achieving this vision of a “zero-day close” is one of two “bold ambitions” she has set for the company's finance function, alongside automated, continuously updated forecasting. “Rapid advancements in technology and automation have made the idea of a zero-day close a reality,” Yooz said. For OpenAI, the push toward a zero-day close is part of Friar’s larger effort to build an “AI-native finance function,” according to her blog post. This comes as she is also building out her finance team to support a business growing at a rapid pace. The idea behind a zero-day close is to give leaders “a real-time, reconciled and traceable view of the company’s financial position,” according to Friar.
