Expert marketing for ambitious companies across every stage of growth.

We sit at the heart of what you do

We exist to help high-growth companies scale faster and more efficiently. We are your on-site growth engine. 

Whether you’re a scale-up, fully-backed, pre or post IPO or you’re looking for your next growth phase – take a moment and ask yourself …“Who are we and why do we matter?”

If companies struggle to clearly and consistently articulate this then nothing sticks, nothing resonates with customers, the market, or investors. This creates chaos, knee-jerk reactive activities with no meaning and wasted investment.

Leading the charge in Marketing On-demand, we’re scale-up marketing experts delivering commercially impactful programs while minimizing risk.

If “hybrid” has replaced the office, then Marketing On-demand has replaced rigid programs and costs. 

What makes us special?

Deborah and Kelly co-founded Core after connecting over their passion of building and running marketing functions for ambitious technology companies. Having worked for a number of high growth and transformational companies, they are experts in quickly understanding what needs to be done to drive demand and growth.

It’s their blend of strategic vision, tactical agility, and flexibility to help organizations define their Core, own it, accelerate it, and grow that makes them special. Plus, there’s no armchair marketers here.


Learning her trade in-house, Deborah has over 25 years’ experience leading Global Brand, Communications, and Marketing at innovative companies including 3Com, Poly, and Corel. Her expertise spans full-funnel corporate priorities from reputation and awareness to marketing operations, demand strategy and growth initiatives’ helping to propel organizations forward in competitive industries. Deborah has built and mentored world-class, award-winning teams who engage across the business and industry building partnerships, credibility, and trust. With a passion for compelling storytelling and strategic positioning, Deborah successfully led the communications strategy to take Exasol to IPO, while also spearheading their transformational CSR, ESG, and philanthropy initiatives. At Wartsila, she drove brand and marketing M&A for the integration of four brands under a single business unit.


Cutting her teeth in the agency land first, Kelly led global integrated marketing programs for some of the world’s leading brands such as Google, Vodafone and HP. Discovering her love of scale-ups, Kelly launched Zuora, Nest and Box into Europe and Middle East – supporting their global growth investment and acquisition strategies. Following this, Kelly moved in-house where for the last nine years she’s been growing, mentoring and up-skilling growth marketing teams, driving brand to demand programs, overhauling brand identities and messaging, creating categories, overseeing customer success initiatives, delivering award-winning content marketing campaigns, overseeing influencer programs, and shaping corporate and C-suite profiles for investment and pre-IPO at some of the most exciting transformational tech brands on the circuit.

What is Marketing On-Demand?

Marketing On-Demand brings choice. 

Think of us as your in-house marketing powerhouse – complementing and upscaling your existing internal and external teams. Or help you to work out what you need as you grow.

We’ve been there and can cut through. We work to determine the right approach for you at each stage that will bring results. We’ve built an exclusive community of the best of the best. Core Collaborators bring a diverse range of marketing skills that can be switched on and off based on your business needs.

An on-demand and flexible fractional marketing model means Core out-manoeuvres traditional rigid structures and retainers.
