Carl Madaffari has a neat way of describing a career that has lasted more than three decades and wandered through databases, identity systems, product roadmaps, customer meetings, and the executive suite. “I build products customers need and make sure they know about them.” It is one sentence with two jobs tucked inside. First, make something useful. Then explain it without frightening the civilians.
Today, Madaffari is chief marketing officer at OneSource Virtual, the Dallas company that handles payroll, tax, benefits, payments, and finance work inside the Workday ecosystem. Until August 2026, he also carried the chief product brief. OSV's decision to appoint a dedicated chief product officer was a sign that its payments ambitions had become large enough to need another desk. Madaffari kept marketing. The title narrowed; the long-running assignment did not. His work remains translation.
That word can sound soft beside “engineering” or “operations.” It is not. Enterprise technology is full of important things that are spectacularly difficult to describe: deterministic matching, payroll tax, leave compliance, invoice processing, data persistence. Madaffari's career has been spent at the seam where the system must survive contact with a customer. His particular advantage is that he once lived deep inside the system.
The education of a technical storyteller
Madaffari moved to the Dallas-Fort Worth area in 1987 and studied computer science at the University of North Texas through 1991. His early work included IBM, systems integration at BancTec, and database administration at Citi. The nouns are telling: systems, databases, integration. This was not a career that began with a mood board.
At Citi, he began applying technical skills to marketing problems. In 2000, he joined Epsilon as a database administrator. He stayed for about twenty years as the company passed through successive stages of growth and ownership, ultimately becoming part of Publicis. Madaffari moved with it, from technology delivery and strategic partnerships into senior roles spanning database solutions, marketing technology platforms, product, and marketing.
On an Advertising Week stage in 2018, he introduced himself with refreshing literalness: “I started off as a very technical person, managing databases, systems integrations, those types of things.” During the previous three or four years, he said, he had migrated toward marketing, “helping tell our story to our clients.” Careers are often narrated as a ladder. His looks more like a bridge built from both banks.
AND SYSTEMS
STRATEGY
STORY
The presentation itself was a useful specimen of his style. The subject was identity resolution, a swamp of cookies, device IDs, match rates, privacy, and attribution. Madaffari and his co-presenter kept tugging it back toward plain questions. Is the match accurate? Can the audience actually be reached? Does the identifier persist over time? A large number without those answers was mostly decorative.

It was a database lesson with a broader moral: inspect the foundation before admiring the dashboard. Madaffari later brought the same suspicion to the rush around customer data platforms. Tools, he argued, could not substitute for strategy, persistent identity, or sound architecture. Vendors were eager to rename familiar machinery. He was more interested in whether it worked.
The useful interruption
Then came a career move notable for its absence of polish. Madaffari left Epsilon in 2021. In a public reflection the following year, he described the long run as rewarding, exciting, and exhausting. He called himself a “semi-retired” data and marketing strategist and said he needed a break.
An opportunity at Tenerity arrived quickly. He jumped into a pre-sales role, helping shape the go-to-market approach for a new product. Then he noticed that enthusiasm and capacity were not the same thing. He did not have the energy the organization needed, he wrote, and left. After more than twenty years without quitting a job, he had left two in one year.
Corporate biographies prefer clean momentum: each box larger, each arrow pointing northeast. Madaffari supplied a more believable diagram. He stopped. He recharged. He reconnected with former colleagues without turning every conversation into prospecting. One of those conversations, with a longtime mentor, became a request to help Kobie Marketing. He served as interim chief technology officer during a transition, working on quality and cloud infrastructure stability.
There is an appealing lack of theater in that sequence. The pause was not branded as a sabbatical designed to produce revelation. It was a practical response to fatigue, followed by work that arrived through a relationship. The engineer in Madaffari seems to have debugged the career in the same manner he might inspect a system: observe what is actually happening, remove the failing assumption, try the next sensible thing.
Beyond the paycheck
OneSource Virtual gave that second act a new domain. The company works on chores that are invisible when handled well and unforgettable when mishandled. Payroll must be accurate. Taxes must be filed. Benefits must reconcile. Leave rules multiply. Invoices must find their way through approval and payment. Nobody throws a parade because the direct deposit arrived on schedule, though many meetings occur when it does not.
Madaffari joined OSV in 2022 and moved into senior product management. His brief was to turn complicated market needs into focused product choices and to build teams that could carry those choices to customers. At HR Tech in 2024, he presented a session titled “Beyond the Paycheck,” connecting payroll efficiency to the experience of the employee receiving the money. The technology mattered because the moment mattered.
His comments around leave administration make the same turn. The administrative problem is compliance with hundreds of rules. The human problem is that an employee needs a process that is smooth and transparent during an important life moment. Product language often chooses one side or the other. Madaffari joins them: less burden for benefits leaders, better treatment for employees, one connected system underneath.
In 2025 and 2026, his role expanded to chief product and marketing officer. It was an unusually explicit marriage of the two halves in his personal formula. Product listened, prioritized, and built. Marketing gave the work a vocabulary. By August 2026, OSV's product scope, particularly in payments, had grown enough for the company to recruit payments veteran Sarah Owen as chief product officer. Madaffari stayed on as CMO, preserving the customer-facing half of the bridge while a dedicated executive took the product organization forward.
Bring the real question
The most revealing glimpse of his working personality may come from a customer event rather than a product launch. While emceeing OSVConnects gatherings in the Bay Area in 2026, Madaffari looked at the roundtable prompts and told the audience to forget them. “You came here with something,” he said. A problem they could not crack, a worry, an obstacle. Nine out of ten people had one. The tenth, he joked, might be there for the free lunch, which was also fine.
The joke worked because the invitation was serious. He wanted the room to stop performing the event and use it. Customers began discussing tactical problems. Madaffari described a buzz at the tables and framed OSV's ambition as a community of payroll and payments specialists who help one another, not simply a service provider broadcasting at an audience.

That instinct completes the arc. The young systems integrator wanted disparate machinery to communicate. The database administrator wanted records to resolve to the correct person. The product leader wanted customer problems to shape the roadmap. The marketer wants the value to arrive in language a buyer can use. Different objects, same work: find the connection and make it hold.
Away from the office, Madaffari's listed interests include travel, photography, and music. All three reward attention to pattern and composition, though it would be too tidy to turn hobbies into a management theory. It is enough to note that the executive who spent years insisting on accurate identity also enjoys looking carefully.
His career offers no grand reinvention, and that is its charm. The technical foundation was never discarded. It became more useful as the audience widened. The break did not erase the first act. It made room for the second. At OneSource Virtual, the two executive roles have now become one again, but Madaffari still occupies the same durable territory between what a system does and why anyone should care.
