VAST INTERACTIVE CONSULTING LEADERSHIP
I’m Catherine Llewellyn, founder of Vast Interactive Consulting and Duke University graduate. I started Vast in 2007 after years at traditional and digital agencies in Account Management because I wanted to create the digital content and bring agency-level digital marketing to small and mid-sized businesses without hefty retainers. I also wanted to be an entrepreneur and remove layers of bureaucracy so I could be hands-on with each client, campaign, and digital asset, from initial concept to performance analytics.
For my clients, I am your digital strategist, content creator, campaign manager, data nerd, and partner in growth. Think of it as hiring the brainpower of an agency, wrapped into one dedicated consultant with deep experience helping brands and businesses succeed in multiple industries, competitive settings, and marketplaces.
Before founding Vast, I worked on national accounts at both traditional and digital agencies in my twenties — Octagon Marketing on BMW, BBDO on Cingular Wireless, and Ant Farm Interactive | nurun on Equifax and GDEcD to name a few. I also applied my skills in corporate roles as an eCommerce Manager and Content Strategist at DS Services (water.com), Razorfish, and Mohawk Industries most recently after COVID, before returning full-time to lead Vast and focus on my company’s vision.
As Chief Digital Marketing Consultant of Vast, I help privately-owned businesses grow by auditing digital marketing channels, creating digital content for multiple marketing uses, running paid campaigns that run off ROI, and analyzing results to show the measurable impact. Among all the digital marketing channel levers, I love uncovering the stories that inspire, refining brand messaging and turning ambitious goals into practical strategies that make growth feel smart, fun, and sustainable.
I partner with privately-owned companies, SMBs, and Start-ups to turn digital marketing into real growth engines. Schedule a call with me if you want to talk digital marketing, business challenges, or even Duke Basketball — I’m always up for a good conversation!
