I founded Krizik Marketing Group by accident. I like to think that it has brought my brand of simple concepts, delivered consistently over time to drive marketing excellence. I love collaborating, innovating, and keeping up with all things ERP.

Whether it is creating marketing plans, optimizing websites, driving lead gen activities, creating social buzz, or diving into industry niches, I bring passion and creativity to the table.

Since 2001, I’ve held roles including Director of Marketing for ERP VARs, Director of Partner Marketing at Acumatica, the Cloud ERP, and Virtual Marketing Director at a variety of B2B firms.

Marketing is hard. While we can’t make it easy, we can deliver clear, actionable strategies, ongoing tips and education, and a commitment to filling your pipeline with the right opportunities.

I finally found the perfect fit – taking my years of technology experience in consulting, training, support, marketing, in the ERP / VAR / ISV world and using it to help businesses with their marketing strategy, content, and execution. 

From the technical trenches, to answering support calls, to teaching classes and running internal ERP systems, I worked my way into my marketing and realized this is where I belong.

With deep knowledge from 30 years working in all areas of software companies, I am a pro at translating business visions into marketing strategies.  One of my magic talents is turning geek speak into friendly content for decision makers.

Fun Fact:  I worked with the very first version of Microsoft Dynamics CRM (1.0) and wrote the first end-user training manual.

I am a writer by trade, an artist at heart, and an incurable nerd all the rest of the time. While I didn’t grow up with accounting software dreams, ERP is my current passion. There is a simple reason for that: helping small businesses grow.

Effective marketing is a great equalizer. I know from experience that the biggest firms aren’t always necessarily the best firms. What gets me going is the talent that exists in the niche, the boutique, the startup. I believe their purpose is higher than simply waiting to be gobbled up by a bigger fish (whatever you do – don’t ask me for my paraphrased version of the Parable of the Bricklayers). 

My specialty resides in creative messaging and modern visual marketing tactics. I believe in the power of well-written copy, beautiful images, and engaging video.

Sean McMullen

I find marketing to be a perfect meeting of two interests of my brain. Creating creative content and analyzing data. What excites me most about marketing is the constant evolution – staying on top of digital trends while building authentic connections between businesses and their audiences.

With over 3 years of agency experience, I’ve honed my skills managing comprehensive digital campaigns across social media, paid advertising, and content creation. My background spans multiple sectors including health & wellness, non-profit, education, and now the ERP industry. This gives me a unique perspective on how different audiences engage with marketing messages.

My real education continues every day as I dive into the latest digital marketing technologies and strategies. While I’m still new to the ERP industry, I’m constantly learning something new every day by creating the best content for Krizik Marketing clients – and I love how this specialized knowledge is expanding my marketing toolkit. I’m particularly passionate about inbound marketing methodologies and how they can transform the customer journey.

My specialty lies in translating complex marketing concepts into actionable, results-driven campaigns. Whether it’s optimizing Google Analytics data, crafting social media content that resonates, or researching industries to help clients find future customers more effectively.

I love working in environments where I can contribute my digital expertise while also expanding my knowledge from seasoned professionals who understand the nuances of B2B marketing. Working with Donna and Jen has been fantastic for this.
