How OpenAI builds finance culture
OpenAI’s former controller explains how you get your finance team to adopt AI and build tools that are actually useful.

Note from the author
“AI in finance/accounting” sounds great. But, how do you build a culture that leads your team to consistently find new (powerful) use cases for AI that are relevant to your team’s work?
That’s what we’re diving into today…
ICYMI: Join our exclusive interview showing with OpenAI’s former Controller, Sowmya Ranganathan. Get her framework for building AI-powered accounting processes at OpenAI and three ChatGPT use cases for accounting.
Today's key takeaways:
AI culture: How to build it the right way
Action audit: Host your first hackathon

Stripe data: AI startups = faster than SaaS ever was
✨Building AI-first culture without engineers
If you don't have a highly technical team or engineers embedded within your finance department, you can still build an AI-first culture that encourages your team to identify, create, and implement powerful AI use cases.
👇 Avoid doing this
Simply declaring "We need to use AI now!" is vague and adds pressure to your team and makes them more reluctant to embrace these tools. Mandates without support or structure will create more resistance rather than innovation.
👩💻 Hackathons aren't just for engineers

Instead, Sowmya brought a common practice from engineering to her finance team at OpenAI:
"We would have team offsites and I would take two, three hours off of that schedule and say, 'This is going to be a finance hackathon.’
Finance teams don't usually do hackathons. So what even is that?
The format was simple but effective:
Team members suggested problems they wanted to solve
They self-organized into small groups
Each group spent two hours exploring solutions with ChatGPT
Teams demonstrated their results in a one-hour showcase
Small prizes created friendly competition
This approach yielded practical innovations while building comfort with AI tools. Eventually, this bottom-up experimentation aligned with top-down objectives:
"We encouraged bottoms-up adoption and we continue to host these hackathons. But then we also have OKRs and other performance goals tied to what could be streamlined and automated."
👷♂️ Restructuring your teams for an innovative future

Reflecting on her OpenAI experience, Sowmya predicts a fundamental shift in accounting team structures:
"The teams of the future will be smaller, they will have more breadth, they will be more plugged into the product and the business. What people really need in this new world is agency. You see a problem, you recognize it's a problem by yourself, and go try to solve it by yourself."
This requires a mindset shift from valuing manual effort to prioritizing outcomes:
"If you take a lot of pride in your manual work, you need to question why and channel that energy to a different way of getting things done. If you were the founder of a business, you care about the outcomes. You don't really care about how long it took someone to do something."
📋 Steps to building AI-first culture
For finance leaders looking to apply these lessons to their own organizations, Sowmya offers this advice:
Invest in finance data infrastructure: Put your data warehouse at the center of your finance operations, not as a downstream reporting function.
Embed AI into your tech stack: Choose vendors with AI capabilities already built in rather than trying to layer AI onto legacy systems.
Give direct AI access: Empower the people closest to problems with AI tools rather than centralizing AI capabilities.
Create low-stakes learning environments: Hackathons and exploration time build comfort with AI tools without performance pressure.
Start small and test constantly: Cross-check AI outputs against known good data until you build confidence in the results.

📝 Action audit
Start with a familiar process: Choose one monthly recurring task everyone knows well and use AI to reimagine it, building confidence through working with familiar data.
Run a 2-hour mini-hackathon: Have team members tackle one manual process with ChatGPT and award a small prize for the best solution.
Create a repository of AI wins: Create a shared channel for team members to post successful AI use cases and time saved. Highlight these in meetings to build momentum.
📲 AI is already everywhere

Whether we realize it or not, AI is already embedded in many of the tools we use everyday, including Rippling Spend.
📸Employees can take photos of their receipts and AI extracts key information to turn those receipts into ready-to-submit expenses.
