Chief of Staff to the CEO at Iterable - the AI-powered cross-channel marketing automation platform that helps the world's leading brands engage millions of customers in real time.
The person who makes the trains run on time at a $342-million-funded enterprise SaaS company rarely gets a profile. Carrie Messner is that person. As Chief of Staff to the CEO at Iterable, she is the connective tissue between an ambitious executive team and the operational reality of a 650-person company competing at the top of the marketing automation industry.
Iterable is not a small bet. With $200 million raised in its Series E alone - and a platform serving retail, healthcare, financial services, media, and e-commerce clients simultaneously - the company operates at a scale where coordination failure has real consequences. Messner's job is to ensure it doesn't.
Her path to this seat was not the conventional route. She didn't come up through product or engineering. She came from the world where creativity meets accountability: digital agencies. At Odopod, an acclaimed San Francisco digital experience agency, she ran client services - translating between ambitious design teams and demanding clients. That's a role where you learn fast or you flame out.
From there, she made the jump to Autodesk, one of the most complex software companies in the world, with a presence spanning construction, manufacturing, architecture, and media. She spent five years in senior Chief of Staff roles there - first supporting the Media and Entertainment Product Line Group, then navigating the labyrinthine world of Cross Industry Strategy and Marketing. Autodesk is not a place where people learn to operate at a small scale. It's where they get a graduate degree in enterprise-grade complexity.
Now at Iterable, she applies that toolkit to a company moving faster, operating with more urgency, and - in the words of her colleagues - with a leader who is "smart, professional, calm, driven and a true leader." That description is not marketing. It's what happens when someone has spent two decades navigating the gap between what organizations say they want to do and what they actually get done.
The Chief of Staff role itself is one of the more misunderstood positions in modern business. It is not a glorified assistant. It is not a policy analyst. At its best, it's a force multiplier for the CEO - surfacing the right information, building the right cadences, unblocking the work that matters. Messner has held this role in two very different organizations (Autodesk and now Iterable) and built a track record that goes back even further, through Tenthwave Digital, Clock Four, and the early days of interactive marketing at Havas/Kadium.
At Iterable, the operational stakes are high. The platform serves as the brain of enterprise marketing programs - orchestrating email campaigns, SMS, push notifications, in-app messaging, and web content across millions of customer touchpoints simultaneously. The company's technology stack includes everything from Snowflake and Databricks to Apache Kafka and Anthropic's Claude. Getting 650 people aligned behind that much complexity - without losing speed or coherence - is exactly the work Messner does best.

The Chief of Staff title has become common enough in enterprise tech to be misunderstood. Some versions of the role are organizational therapy. Others are a landing pad for executives in transition. At its best, it's something more precise: the function that makes a CEO's attention go further.
Messner's version of the role - developed over a decade across Autodesk and now Iterable - sits squarely in the high-impact category. She builds the cadences, manages the information flows, and ensures that the things the CEO needs to focus on are the things the CEO is actually focused on.
In a company with 650 employees, multiple product lines, and a platform serving industries from retail to healthcare, that's not a small task. It requires knowing the business at a level of depth that most executives don't have time to maintain - and knowing which details actually matter.
The agency world is an unusual training ground for enterprise operations. It's high-pressure, client-driven, and requires holding creative ambition and commercial reality in tension simultaneously. Messner spent years in that environment - from early digital marketing at Havas through client services leadership at Odopod.
That background shows up in how she approaches her work now. Agency people tend to be faster, more adaptable, and more comfortable with ambiguity than their enterprise counterparts. They've also learned - sometimes painfully - that what clients say they want and what will actually serve them are not always the same thing. That distinction matters when you're helping a CEO navigate a complex organization.
The Autodesk years added the other dimension: how to operate at scale, within process, across a global company with deep institutional complexity. The combination is rare. It's what makes a Chief of Staff effective in a high-growth SaaS environment like Iterable.
Iterable is a cross-channel customer engagement platform built for enterprise brands. Powered by AI and designed for omnichannel orchestration, it enables marketers to deliver personalized messages across email, SMS, push notifications, in-app messaging, and the web - at scale, in real time.

Customer data unification, behavioral analytics, real-time data activation, and CRM integration. The foundation for personalization at scale across enterprise organizations.
Iterable competes in one of the most crowded categories in enterprise software: marketing technology. The company's differentiator is depth and flexibility - a platform designed to serve brands with genuinely complex customer engagement needs, not brands looking for a quick email tool. That positioning puts Iterable in direct competition with much larger players, which means operational efficiency, product velocity, and strategic clarity are not optional.
The company's technology stack reflects that ambition. Iterable builds on a foundation of Snowflake, Databricks, Apache Kafka, and Kubernetes. It runs on AWS infrastructure, uses React and GraphQL for its interfaces, integrates with Salesforce and Marketo, and has incorporated Anthropic's Claude into its AI capabilities. Coordinating a product built on that stack - while serving retail, healthcare, financial services, media, and e-commerce clients simultaneously - requires organizational discipline that doesn't happen by accident.
That's the environment in which Messner's role matters. The Chief of Staff to the CEO at a company like this is not managing a calendar. She's managing organizational coherence across 650 people, multiple product lines, and a technology platform that touches millions of consumer interactions daily. She ensures the CEO's priorities translate into organizational behavior - and that the information the CEO needs to make good decisions actually reaches them.
With customers spanning industries from retail (including direct-to-consumer brands) to financial services and healthcare, Iterable's operational demands cut across every major category of enterprise software buyer. Messner's team-wide perspective - seeing what's working across verticals, where execution is slipping, and where the next strategic opportunity sits - makes her one of the more informed people in any given room at the company.
The San Francisco Bay Area concentration of enterprise SaaS companies creates a particular kind of professional environment: one where operational talent compounds across careers, and where people with Messner's breadth of experience - agency, enterprise, startup-scale SaaS - are unusually valuable. She has navigated that environment successfully across multiple companies and multiple eras of the tech industry.
The platform Messner helps coordinate is built on a serious technology stack. Selected highlights:
