August 20, 2026, (Inside AI) — Stampli compressed a six-week product launch into roughly 77 hours of active work by pairing ChatGPT Work and Codex with human oversight, the company said. The launch of Deep Finance, its executive spend intelligence product, would have required an estimated 243 hours without the AI tools.
The procure-to-pay platform used Codex to turn evolving product decisions into review-ready assets across a seven-part blog series, launch emails, a webinar deck, social and paid creative, a PR Newswire release, the Deep Finance web page, and sales enablement materials. Codex also handled roughly 90% of the polished animation work before a contractor finished the opening scene.
The result was a 3.16x faster production cycle, or about 166 hours saved. But the deeper story is not speed alone. Stampli's product marketing team has built a daily infrastructure that keeps product knowledge current, surfaces business insights, and moves ideas to market faster.
From prototype demo to public launch in six weeks #
Deep Finance moved from an initial prototype demo to a public go-to-market launch and first shipped product in about six weeks. Design resources and outside contractors were already committed to other priorities, so the team leaned on Codex to create assets in parallel.
Before AI, keeping product materials current required interviewing product managers, reading Jira tickets, reviewing GitHub, and working through meeting notes. Now a GPT-powered system gathers information from product systems and meeting notes, then helps keep help center articles, presentations, and one-pagers up to date.
Melad Zahedi, Director of Product Marketing at Stampli, said the automations have multiplied output. "It's multiplied the output of a small team by 10x, putting out hundreds of pieces of content on a weekly basis, where it was limited to just a couple before," Melad Zahedi, Director of Product Marketing, Stampli
Zahedi also uses GPT-powered automations as a "second brain" to organize information across a schedule filled with back-to-back meetings. "Being able to go to every meeting prepared with context, understanding what is needed from me in that meeting and how to stay efficient with my time, has been an amazing benefit," Melad Zahedi, Director of Product Marketing, Stampli
Real-time data retrieval replaces half-day reports #
In one executive meeting, a question arose about metrics stored across HubSpot and other systems. An employee asked Codex to retrieve and analyze the relevant data during the call. "This is something that would've taken our FP&A team half a day to put a report together, give us a model, and give us an answer that we felt confident in. Someone was able to do it with 20 seconds of keystrokes," Melad Zahedi, Director of Product Marketing, Stampli
The time saved let product marketing spend less time reconstructing context and more time advising leaders on product and company strategy. The team became more involved in advising VPs and C-suite leaders on corporate and product strategy.
ChatGPT Work also serves as a thought partner. Employees use it to deepen their knowledge, brainstorm ideas, create stakeholder personas, and test recommendations before presenting them to leadership. Teams across product, marketing, customer success, sales, and enablement are using the same tools to take ideas from prototype to launch.
Stampli is now exploring how to apply that approach across more products, workflows, and go-to-market programs. For Zahedi, the larger opportunity is expanding what employees believe they can take on. ChatGPT Work and Codex have helped his team learn new disciplines, build its own systems, and spend more time on decisions that move the company forward.
