Hi, I’m Catherine Llewellyn. Principal Consultant and Founder of Vast Interactive. I bring over 20 years of corporate, agency, and consulting experience straight to your business, personally auditing your ecosystem and leading the execution.

So many small businesses are running digital marketing campaigns that don't talk to each other. We should talk.

The Proof: Real Business Growth Built on 25+ Years of Experience

Award-winning Atlanta digital marketing consultancy delivering elite strategy, content creation, and implementation from a 25-year corporate and agency veteran.

"It wasn’t until I met Catherine of Vast Interactive that I truly understood how impactful a great marketing professional can be. We started with website updates and then quickly progressed to specific SEO plans to optimize our local reach. What really sealed the deal was when I got a call from someone in Alpharetta who did a search and saw us come up as the #1 response. After 3 years, I finally hit my first profitable month and haven’t looked back since."
