Our Humble Beginnings: Internet Marketing for Small Businesses

KARMA jack Founder, Joel Sellentine

In 2017, entrepreneur Joel Sellentine realized that old forms of advertising were dying away and that the future was digital. He saw a valuable opportunity for small businesses to grow their companies quickly and profitably through digital marketing.

Sellentine founded KARMA jack with the mission of helping businesses grow successfully. He is an expert at taking a business that has plateaued and moving them from not getting results, feeling stressed and frustrated, to seeing their business thrive.

As time progressed, he built a digital marketing team of eclectic and skilled people that make up KARMA jack today.

KARMA jack is not your average digital marketing agency. We are founded on solid principles of service, quality and results.
COO Halley Karas comes from 5-star service hotel leadership. Her ability to execute on strategies while creating an unbelievable customer experience far exceeds what a typical marketing company offers.

Joel Sellentine combines business savvy with an innate ability to visualize a clear path to growth. He built the company not from a business owner’s perspective, with a focus on tangible results. If it doesn’t drive revenue, it doesn’t make sense.

When you reach out to us, you will not get a sales pitch.

You WILL get rock-solid advice on how to grow your business. We only share with you services that you might need.

You WILL get a clear plan that you can execute yourself, or hire us. We want you to be successful, because we care.

While we’re a digital marketing company, the added value we offer is having a team of consultants on your side.

We love to help and willingly provide amazing internet marketing services to all businesses that request information. But we don’t work with every company. Sorry!

Each business is carefully vetted to ensure we see a high return on their investment.
Our innovative marketing strategies utilize targeting, social media, high-converting landing, and remarketing. Why? This method provides long-term, sustainable growth.
