“As a pay-per-click
advertising agency, we
live and breathe online


Mark Stubblefield

Co-founder, CEO

As a pay-per-click advertising agency, we live and breathe online advertising. It’s in our blood. It’s even in our dreams. And we work like crazy to make our clients successful through it.

As a company, we’re a lean team of digital advertising experts eager to increase your bottom line — but not just because we’re “nice guys.” We know that return on investment is what drives your advertising decisions, and that the best way to earn your continued business is by delivering you great results. That’s where the “work like crazy” comes from.

As individuals, we bring decades of advertising experience and savvy to the table. Collectively we’ve served Fortune 500 and above organizations, multi-million dollar retailers, non-profits, and local businesses, and we know how to make our services work for each business vertical.

About StubGroup Advertising’s Founders

Mark Stubblefield
Co-founder & CEO

“Take us to your leader.”

StubGroup was founded by entrepreneur and marketing expert Mark Stubblefield. Mark started his first business at the ripe old age of fourteen, and since then he’s never looked back (except when behind the wheel, which his driving-instructor father strongly encouraged).

From launching and reorganizing multi-million dollar businesses that were wildly successful, to enduring the painful process of watching poorly managed businesses self-destruct, to working in the fast-paced, billion-dollar world of private equity, Mark has many years of extensive, real-world business experience under his belt and knows what it takes to make a business succeed. Along the way he has formed many lasting relationships with super-talented, creative marketing people that love what they do and do it well. StubGroup is the culmination of Mark’s business experiences and relationships, packed into a creative company designed to help other businesses achieve their digital marketing goals.

Tim Horn
Co-Founder & Managing Partner

A “child” of the digital age, Tim is a fourth-generation business owner with marketing in his blood. Tim’s unique work experience has allowed him to oversee and execute ROI-driven digital marketing campaigns from all sides of the marketing table: as marketing director at a multi-million dollar retail company, as owner and marketer of his own online businesses, and as an expert digital marketing services provider.

Because he is an avowed abstainer from all things coffee, Tim’s daily buzz comes primarily from two alternative sources of motivation: making his clients successful, and beating Mark at Madden NFL.
