Patricia Spiller arrived at Stanford with a telecommunications engineering degree, a couple of years in America penciled into her mental calendar, and a field of possibilities she had not known existed. Clean energy. Consulting. Venture capital. The vocabulary of Silicon Valley widened the map. So did the people: Latin American classmates, international students, friends who would eventually scatter around the world. She had left Uruguay to study business. What she carried into business was an engineer’s instinct for systems.
The move had been forming for years. Her parents had encouraged the idea of studying overseas as a way to encounter more of the world. Her father had done an exchange in the United States and filled the family home with stories from it. Once Spiller finished engineering school, graduate study in America felt like the next experiment. Stanford provided a protected place to make the jump: new classmates arrived at the same time, international students found one another, and unfamiliar careers suddenly had names. She later remembered the period as so motivating that the days seemed too short for everything she wanted to absorb.
That instinct appears everywhere in the career that followed. At Abbott, where she spent close to seven years, the work moved through sales, product marketing, demand and strategy. She helped launch technologies in global markets. Then, in 2016, a former manager who had remained a mentor introduced her to the leaders of a small connected-technology company called Livongo. Spiller liked the mission, the model, the people and the culture. She joined when the company had roughly 40 employees.
The important part was not that Livongo had a growth-marketing job waiting. It did not, at least not in the form Spiller imagined. She saw an opening for a dedicated growth function. She had never built one. She had a hypothesis, received the trust to pursue it, and started assembling the team.

A function built from zero
Spiller said the team expanded Livongo’s user base by a factor of 120. The organization she led grew to about 40 people.
The smallest launch that can teach you something
Spiller’s public explanations of growth rarely sound like advertising doctrine. They sound like product development. Define the minimum useful release. Launch quickly enough to collect a signal. Talk to users. Adjust. When Livongo introduced a mobile app, she described the approach in three verbs: learn, iterate, move. A focus group gave the team more detail about how people actually used the product, and the team fed that evidence into the next version.
The humility matters. An A/B test begins with a hypothesis, not a verdict. One of Spiller’s own essays was titled “When A/B testing, be humble.” Marketing people can become attached to the clever line, the polished campaign or the strategy that looked airtight in a conference room. A test returns the conversation to behavior. The customer gets a vote.

Her view of competition was equally broad. A connected service does not compete only with a comparable service. It competes with every app, message and small demand already pressing on a person’s day. That changes the marketer’s assignment. Attention is not sitting in an industry bucket waiting to be collected. A product has to fit a real routine and earn the next interaction.
A stack of tools is not a team
By 2019, the marketing-technology market already contained thousands of products. Spiller’s response was to look beneath the stack. She sought people with analytical grounding, an ability to learn unfamiliar systems, care for detail and genuine interest in the work. Specific software could be taught. The durable advantage was a person who could understand a business need and translate it into a technical requirement.
Translation is the underappreciated job. Marketing, engineering, product and analytics often share a dashboard without sharing a language. Spiller described marketing technology as an enabler for the wider group, not a secluded service desk. A strong leader helps both sides see the same problem and links automation to something customers or colleagues can actually value.
Her standard for a marketing technologist reflects that bridge. The person must understand the commercial question well enough to avoid automating noise, then understand the system well enough to turn the question into a workable specification. For especially complicated technology, she has argued for keeping a senior specialist close enough to guide the hardest decisions. The point is not to make every marketer an engineer. It is to build a group in which business context and technical depth can meet without a long chain of translation errors.
Her management philosophy follows the same architecture. Give people substantial responsibility. Make sure they have what they need. Spend time listening and removing barriers. Think through the hard parts together. The manager designs the conditions in which judgment can travel quickly through the organization.
This explains why the 120-fold user figure is more interesting as an organizational story than as a trophy. A temporary spike can come from a channel. Repeated growth requires a group that can generate ideas, run clean tests, read evidence and keep its footing while the company changes around it. Livongo went public in 2019. It combined with Teladoc the following year. Spiller then led growth marketing for the combined business. The machinery had to work at several different scales.
The message begins outside the company
Spiller applies the same outward gaze to content. A brand naturally wants to begin with its product, its announcement and its preferred language. She argues for beginning with the audience’s need. In her framework, some content is designed to prompt an immediate action; other content builds familiarity and trust over time. The goals are different, so the measures should be different too.
Her phrase for the process is “place bets.” Try several ideas. See which one resonates. Put more energy behind the winner. It sounds less tidy than a grand annual plan because it is more honest about what a marketer knows before an audience responds. Strategy supplies the direction. Experiments supply the correction.
Effective content starts with consumers’ needs, not what the brand wants to sell.Patty Spiller, on content strategy
There is an appealing continuity here. Her parents encouraged her to study abroad so she could open her mind, see the world and enlarge her opportunities. At Stanford, that opening became literal: entire industries appeared. At Livongo, feedback opened the product to how people behaved rather than how the company expected them to behave. As a manager, listening opened the team to ideas that did not need to originate at the top.
The engineer’s job in an AI company
Spiller joined Tempus in 2021 as senior vice president and head of marketing. She now serves as Chief Marketing Officer, Data & Apps, leading corporate marketing and the marketing of data and AI solutions for provider and biopharma customers. The technical material is dense. The audiences bring their own expertise. A message has to remain accurate while becoming understandable.
The title marks a change in scope, but the underlying problem is familiar. Earlier in her career, she helped introduce physical technologies in markets around the world. At Livongo, she worked on the connection between a digital product and the habits of its users. At Tempus, the portfolio brings data, software and artificial intelligence into the same narrative. Each setting demands fluency in what the product does and restraint about how much the audience needs to hear at once. Clarity is less about removing complexity than arranging it in a sequence another person can follow.
That makes the CMO a translator again. A product video is not decoration around the product. It can show how several capabilities connect into one coherent system. A campaign is not a pile of claims. It is an argument about why the work matters to someone outside the building. Spiller’s path through engineering, global product launches, connected technology and growth gives her more than one professional language to use.
It also gives her a recognizable operating cadence. Start with the person on the other side. Reduce an idea until it can produce evidence. Let evidence challenge taste. Hire learners. Give them authority. Treat technology as an enabler. Tell the story clearly enough that a complex product can enter an ordinary conversation.
Spiller once wrote about deliberately stepping outside the comfort zone, a concept she said she discovered only in her late twenties. Her career can be read as a sequence of those steps: Uruguay to California, engineering to marketing, a large company to a 40-person startup, an unbuilt function to a team of 40, and growth leadership to an AI company’s C-suite. None erased what came before. Each added another layer to the system.
The useful thing to steal is not a slogan. It is the loop. Curiosity produces a bet. A small release produces a signal. The signal produces a better decision. A trusted team makes the loop turn faster. Growth follows as an output, not an incantation.
