Content and Data Are Inseparable
Mark Debenham came to growth marketing the long way round, through children's publishing and B2B content before moving steadily toward the data. Now VP of Growth Marketing and Marketing Operations at Adverity, the integrated data platform, he runs paid media, content and marketing operations from a single conviction: content and data are two sides of the same coin, and neither works without the other. He is a flywheel believer who admits the reality is often closer to a pretzel, a HubSpot devotee, and a manager who measures success less by a number than by the story a customer tells about why they came. He builds teams on curiosity and brutal honesty, and runs an internal awards show to keep it that way.
We're writing history at the moment. It's uncharted territory.
Mark Debenham is VP of Growth Marketing and Marketing Operations at Adverity, the integrated data platform, where he combines a content marketing background with data-driven growth strategy to drive new business and optimise performance across inbound channels. With over fifteen years of experience spanning B2B and B2C marketing on both agency and in-house sides, Mark brings an unusual perspective to the growth marketing role: one rooted in storytelling first, scaled through data.
Mark's career began in the publishing industry, working in both children's books and B2B content marketing. That early immersion in editorial craft and audience engagement shaped a lasting conviction that content and data are inseparable: you cannot create genuinely engaging work without listening to your audience, and you cannot scale that listening without robust data foundations. He gravitated naturally from content production into inbound marketing and then marketing automation, each step bringing him closer to the data layer that underpins growth strategy.
Before joining Adverity, he held roles including building a marketing automation function from the ground up at pi-top, an education technology company, where he managed a full website migration from WordPress to HubSpot. That hands-on experience with the HubSpot ecosystem became a defining feature of his approach: Mark has been using HubSpot for over a decade and is a member of HubSpot's Customer Advisory Board. He has spoken at HubSpot's GROW London 2022 and INBOUND 2023 events, sharing insights on flywheel philosophy, CRM alignment, and data-driven growth models.
At Adverity, Mark leads a team structured across two functions: growth marketing (managing paid advertising across Google, Bing, LinkedIn, Facebook, Instagram, and emerging channels, alongside a content team producing thought leadership, blog content, and Adverity's own podcast) and marketing operations (overseeing HubSpot automation, email workflows, reporting, CRM data integrity, and integration with Adverity's own product). He champions a flywheel model over the traditional funnel, prioritising attract-engage-delight cycles that generate sustained momentum through customer advocacy rather than requiring constant top-of-funnel feeding.
Beyond Adverity, Mark is a recognised voice on the intersection of data and creativity in marketing, contributing to publications including LBB Online and writing for the Adverity blog on topics from marketing mix modelling to conversational AI. Based in London, he is known among colleagues for fostering psychologically safe team cultures, exemplified by the company's Addie Awards, an internal recognition programme inspired by The Office's Dundie Awards that started during lockdown and has become a beloved fixture of Adverity's working life.
We've suddenly got a whole load of other colours on that palette now, and the canvas is bigger.
What I said about the flywheel, yeah, still think that's accurate, but buying processes can be complicated. They can be long as well. And no team exists in isolation. So sometimes it maybe isn't as much of a flywheel. It can be sometimes more of a pretzel, maybe. So there's twists and turns in there.
Mark is a believer in the flywheel, the attract-engage-delight loop that builds momentum as happy customers recommend you onward, rather than a funnel that has to be fed at the top forever. Then, with characteristic honesty, he punctures his own model. Real B2B buying, he admits, is complicated and long, and no buying team exists in isolation; once several stakeholders are involved, the neat flywheel starts to bend. Sometimes, he says, it is less a flywheel than a pretzel, full of twists and turns. The point is not that the model is wrong but that marketers need frameworks loose enough to survive contact with how people really buy.
For me, it's not just so much about finding out the source of how someone learned about Adverity. It's about finding out what was most memorable for them. So the metric for me isn't so much a number, but it's a story.
The measurement Mark trusts most is also the simplest: he asks every prospect how they heard about Adverity. Self-reported attribution, popularised by people like Chris Walker, cuts through the analysis paralysis of a dashboard with too many numbers. But what he is really after is not the source so much as the memory, what stuck, and why someone chose to engage at that particular moment. For him the useful metric is not a number at all but a story, and a story tells him what to do more of in a way a conversion figure never could. He still runs the sourced and influence models for the board, then validates them against what customers say in their own words.
One quote that I keep finding myself using again and again is this one from Chekhov: don't tell me the moon is shining, show me the glint of light on the broken glass. Show, don't tell. I think it's the most powerful way to navigate the journey you're trying to take your prospect on.
Mark keeps returning to a line he attributes to Chekhov: do not tell me the moon is shining, show me the glint of light on the broken glass. Show, don't tell. Applied to marketing and sales, it means demonstrating value rather than asserting it, taking a prospect on a journey of evidence and experience rather than a list of claims. It is why his team would rather build someone a tailored report or let them feel the product through an interactive demo than send another deck of promises. The literary instinct, carried over from his publishing years, turns out to be a sales one too.
She said, if you were driving around in a pink Ferrari with white spots on it, people would be thinking all sorts. She was like, people are going to have an opinion on you when you're in that position, so you just need to get comfortable with the feeling of being uncomfortable.
A mentor once handed Mark an image he has not shaken. Drive a Ford and no one has an opinion on you; drive a pink Ferrari with white spots and everyone does, wondering if you are arrogant, an attention-seeker or simply successful. Her point was about leadership: the more visible you are, the more people will form views of you, and trying to win universal approval will only hamper your decisions. The lesson he took was to get comfortable with the feeling of being uncomfortable. It pairs with his other rule, that if a thought has occurred to you, others are probably thinking it too, so surround yourself with people honest enough to say so.
