A payment platform becomes noticeable when something goes wrong. A claim stalls. A rule changes. A staff member opens another tab, makes another call, or searches for a number that should already be visible. When the machinery works, it recedes. That creates a strange assignment for a marketer: explain the value of an infrastructure product whose successful moments look like less work.
Missy Miller has built her career inside that assignment. She is the Chief Marketing Officer of Waystar, a healthcare payments software company, and her route to the job has passed through sales, product, corporate strategy, commercialization and consulting. It is a career made from adjacent rooms. Each one offered a different view of how complicated technology becomes something a customer can understand, choose and use.
The title arrived in January 2023. The preparation took roughly 15 years. Miller started at McKesson Provider Technologies in 2008, moved to ZirMed in 2015, stepped out to build a go-to-market consultancy and lead growth work, then came back into the ZirMed lineage through Waystar in 2020. She joined as Vice President of Commercialization, a title that practically announces the bridge she had learned to build.
Clarity is part of the product
Miller once framed the gap in plain terms: people have learned to expect speed, accuracy and transparency from the technology around them. Food arrives with a map. Packages announce their location. A payment workflow, by contrast, can disappear into institutional complexity. Her point was less about comparing apps than about expectations. People carry the standards of smooth digital experiences into every other system they touch.
“In every other part of our lives, we expect technology to provide transparency, speed, and accuracy.”Missy Miller, speaking on revenue-cycle technology
That sentence contains her marketing brief. Waystar sells software into workflows dense with handoffs, rules and administrative labor. A feature list can describe what the platform does. It cannot, by itself, convey the relief of fewer status checks or the confidence of seeing a process clearly. Miller's work is to translate between those layers without sanding away the operational truth.
Her responsibilities at Waystar span brand awareness, client acquisition, engagement and advocacy. Those may sound like familiar marketing buckets. In infrastructure software, they are connected by credibility. A message earns attention only if it resembles the work. A promise earns advocacy only if the product can keep it. Marketing sits close to the operating system of the company because every claim eventually meets a workflow.
Scale changes the storytelling problem: the message must stay clear across many customers, settings and workflows. Company figures are current to Waystar's public materials.
A career built at the seams
Miller earned a Bachelor of Science in Management from Purdue University in 2008. Her listed campus activities already crossed constituencies: president of the Leadership Club for Sales, president of Windsor Hall, a program-development role in Alpha Phi, and participation in leadership honoraries. The record does not need a grand origin myth. It simply shows someone repeatedly volunteering for the coordination work.
At McKesson Provider Technologies, she entered a large technology organization. At ZirMed, she worked in the business that would become part of Waystar. Her roles spanned sales, product and corporate strategy. The sequence matters because each function teaches a different definition of value. Sales hears the objection in real time. Product confronts constraints. Strategy chooses where to focus. Client teams live with the handoff after a contract is signed.

In 2018, Miller stepped outside a single employer's walls. Frances and Company provided go-to-market consulting across marketing, commercial and client-success functions. During the same two-year period, she served as Chief Growth Officer and Chief Marketing Officer at Chameleon Collective. Consulting compresses the learning cycle. A diagnosis has to travel. A plan has to survive contact with a team, a budget and a customer base that the consultant did not grow up inside.
Then came the return. Waystar hired Miller in August 2020 to lead commercialization. By December 2021, she was Senior Vice President of Marketing, charged with a newly expanded team focused on brand awareness, market initiatives and customer engagement. In early 2023, Miller became CMO.
The cross-functional marketing loop

Where does work slow down?
What earns a decision?
What can people repeat?
The team is part of the message
When Waystar announced her CMO appointment, Miller put the emphasis on the group around her. “I'm grateful to work with such a talented and committed team,” she said. It was a conventional occasion for an executive quote, but the wording matches the leadership picture drawn by former colleagues. They describe someone collaborative, direct, goal-oriented and willing to work alongside the team when the work becomes difficult.
Across those colleague accounts, the recurring verbs around Miller are formalize, execute, collaborate and encourage. One wrote that she pairs a view of the future with the ability to turn plans into action. Another emphasized that she works beside the team rather than communicating only from above. Together they sketch an operating temperament: direction plus proximity.
That combination is useful in a category where language can become abstract quickly. “Transformation,” “automation” and “platform” all carry meaning, but each can float away from the person doing the work. A hands-on marketing organization keeps pulling them back to an observable change. How many steps disappear? Which answer arrives sooner? Where does uncertainty become visible? The closer the storyteller sits to the workflow, the harder it is for empty language to survive.
Miller has supplemented that operating experience with formal study. She completed an advanced digital marketing certification through Cornell University and executive education at Northwestern University's Kellogg School of Management. She also earned a revenue-cycle credential from the Healthcare Financial Management Association. The mix is revealing: marketing craft on one side, domain fluency on the other.
From a private workflow to a public company
In 2022, Women We Admire named Miller to its Top 50 Women Leaders in Healthcare list. The following year brought the CMO promotion. In June 2024, Waystar began trading on Nasdaq under the ticker WAY. The company now describes a network handling billions of annual payment transactions across more than one million providers. Miller's remit sits inside that widening circle of attention, where a marketing message must work for customers, partners, employees and a public-market audience.
In 2026, Miller continued to highlight the same themes: automation, clearer financial workflows, customer education and the company's True North client conference. She tends to amplify the company and its teams rather than turn every update into a personal dispatch. That is consistent with a career spent translating an institutional product. The object in the foreground is usually the work.
The aspiration she has stated is similarly collective: simplify healthcare payments and create positive change around them. The phrase sounds broad until it is returned to the small frictions that opened this story. A status found without a call. A task routed without another spreadsheet. A person seeing what comes next. For infrastructure, progress often arrives as an absence: fewer detours, fewer mysteries, fewer minutes spent hunting.
What other operators can steal
Miller's career offers a practical model for people who want to lead marketing in a technical category. First, collect views of the same customer problem from different functions. Second, learn the vocabulary of the workflow deeply enough to know which details matter. Third, treat commercialization as a discipline, not a launch checklist. The product promise, sales conversation and customer experience should point in the same direction.
There is also a lesson in the path itself. The consulting chapter did not break the story; it widened it. Returning to the ZirMed lineage through Waystar did not repeat an old role; it brought new context to a familiar market. The CMO title emerged after Miller had learned the business as an employee, adviser, owner and cross-functional leader.
Complex industries often reward people who can hold two truths at once: the machinery matters, and many people do not want a tour of every gear. Miller's work lives in that editorial judgment. Keep the facts. Lose the fog. Show the better day created by the system. For a company that sells clarity behind the scenes, making the back office visible is both a marketing task and an operating one.
