You’re reading AI at the Top - Our Sunday series on how Fortune 500 enterprises use AI in business.

1. The short version
The initiative: Visa is reforming its product development teams from ten or more people into what CEO Ryan McInerney calls "agentic squads," and reports 80% more code commits on the teams using its agentic toolchain.
The return: The one dollar figure Visa has attached to this is a cost. It booked $563 million of severance that quarter, announcing role cuts weighted toward technology and product on the day the velocity numbers went out.
2. Visa is changing the size of the team
Plenty of AI programs stop at buying licenses and counting seats. What Visa did is harder to undo. It is shrinking the unit that builds a product.
On the 28 July earnings call, McInerney said Visa is "reforming our product development teams that used to be ten or more into smaller and more nimble agentic squads of two to four." Underneath it is a set of AI tools wired together so that work passes from one step to the next without a person moving it along, with people still checking what comes out.
Cutting a product team to a fraction of its size depends on more than staffing. It only works if the pipeline absorbs the work those people were doing, and if somebody is still reviewing the output. McInerney put the review part on the record. How much of the departed work the pipeline absorbs is not something Visa has said.
On the same call, Visa put its own count at "more than 150 AI-powered applications" today and "more than 300 major product releases" shipped over the previous 12 months. That second figure is a trailing-year flow rather than a running total, and the releases are described as major rather than AI, so the 300 counts output and not AI output.

3. The three numbers and the clause under them
McInerney gave the velocity figures in one sentence on that same call: "And the results are meaningful for those teams that are using the agentic toolchain, with 80% more code commits and an 80%-plus improvement in requirement definition from 30 days to 5 days, which has translated to 65%-plus faster feature development."
All three describe one population, the teams already on the toolchain, and Visa did not say what share of its engineers that is. Asked later about adoption, McInerney said deployment had gone well "across the company especially in product and engineering" and that other parts were getting good adoption. He put no percentage on either.
These are before-and-after numbers on a self-selected group of unknown size, and we'd still take them over a seat count, because one is a clean task measurement. Requirement definition going from 30 days to 5 names a job, a baseline and a unit of time. Code commits are just activity, and they can rise without more work getting done. CFO Christopher Suh cited faster consulting projects too, but gave no figure.
4. The only dollar figure attached to the velocity work
Visa's fiscal third-quarter results carry $563 million in severance charges. McInerney told investors the same day that the cuts were "the majority being in our technology and product teams," the same teams the velocity numbers come from. Visa drew no line between the two, and companies cut roles for reasons that have nothing to do with AI. What is on the record is the timing and the department.
Reading Visa's fiscal 2025 annual report, its fiscal 2026 quarterly releases and its newsroom, we found no dollar figure for what Visa's internal AI use returns. Every AI dollar figure we found is either money going out, such as the more than $3 billion on AI and data infrastructure over ten years that Rajat Taneja, Visa's president of technology, cited in 2023, or fraud stopped for clients, such as the $40 billion of fraudulent activity Visa says it helped block in fiscal 2023.
That leaves severance as the one number with a dollar sign on it anywhere near this work. Our Chevron issue found measured savings on one robotics program, which is the kind of number Visa has not yet put beside its velocity work. Full-year results land on 27 October, the next chance for one to appear.
5. The adoption number Visa filed with a regulator
The velocity figures live in a transcript. Visa's adoption numbers sit in an SEC filing, which makes them the most durable evidence in this issue.
The annual report for fiscal 2025 describes an internal GenAI hub for employees and, separately, Visa's own AI assistant for employees, which it says uses agentic AI for self-service. From the assistant's launch in March 2025 through the fiscal year ended 30 September 2025, the filing says, it "has been embraced by nearly 26,000 employees launching over 261,000 AI-powered chats."
That same section gives the denominator, with the workforce growing from roughly 31,600 in fiscal 2024 to roughly 34,100 in fiscal 2025. Nearly 26,000 of about 34,100 people is around three quarters of the company, inside seven months of launch. Put that fraction beside your own.
Nearly 26,000 employees and 261,000 chats works out to about ten each in seven months, which is broad reach and light use.
Our Mastercard issue makes the useful comparison. Mastercard gave a target for how many of its staff it intends to train. Visa gave a count of who actually turned up. One is a plan and the other is a result, and your board will ask which kind yours is.

6. Visa puts its security pipeline on GitHub
Visa says it took part in Project Glasswing, the security effort Anthropic announced in April 2026, and pointed frontier models at its own systems. Anthropic doesn't name Visa among its twelve launch partners, but says more than forty further organizations got access. The result was the Visa Vulnerability Agentic Harness, which McInerney called "an orchestration layer that allows us to use models like Mythos to find and fix issues at AI speed." Visa open-sourced it in June 2026, and an August release extended it into remediation and validation, with tens of thousands of downloads. Taneja said, "AI is compressing the time between vulnerability discovery and exploitation."
The repository is public and free to use, and when we read it on 11 October it showed 2.4k stars and 323 forks. Anyone can download it and run it against their own code. One warning sits in Visa's own instructions. Left on its default setting the tool rewrites the files it is pointed at, so a first run needs the flag that tells it to report and change nothing.
7. What Visa opened up, and what it kept shut
The Vulnerability Agentic Harness: Point it at one piece of your own code whose weak spots you already know. You'll see whether an agentic pipeline finds what your scanners missed, and how a company Visa's size runs discovery, triage, remediation and validation as one workflow. Give it a day.
The Trusted Agent Protocol: Visa announced it in October 2025 with Cloudflare so a shop's website can tell a trusted AI agent from an unwanted bot. The specification opens without an account, and sample code is on GitHub. If you sell anything online, someone should check whether your checkout recognizes an agent, and this is the cheapest way to find out.
The third asset is closed. Visa Intelligent Commerce is a restricted product with gated documentation, so don't send an engineer looking for that sandbox.
8. What to take to your board
Report the population with the lift: Visa's 80% covers only engineers already using its agentic toolchain, a group it never sized. Any velocity number you present needs that clause attached, and if you cannot name the share of engineers it covers, say so before somebody else asks.
Separate the activity count from the task measurement: Code commits rising 80% is activity. Requirement definition falling from 30 days to 5 is a job, timed twice. A timed job survives a hostile question in a way an activity count rarely does, so lead with whichever of yours carries a baseline.
Change the team shape after the tooling lands: If your dashboard still reports seats, squad size is the next move, and a competitor can't buy it. Pick one product line, shrink the team, give it the pipeline, and measure what you measured before. At Visa that's a whole org. In a 200-person company it's one squad and one metric.
Price the cost alongside the gain: Visa put its velocity figures and its severance charge in front of investors together. If your AI program changes which roles you need, that number reaches your accounts whether or not the benefit does, so bring both to the board on one slide.
9. The system prompt your team can test this week
Point this at one of your own AI productivity numbers before it reaches a board deck. It finds the narrowest population the number is actually true for.
You are a velocity claim auditor. I am the executive who will have to present this number, or defend it after somebody else does. Find the narrowest population the figure is true for and tell me what it cannot support. You are not an advocate and not a skeptic. You are a grader.
