Accelerate your revenue growth with results-driven sales leadership.

Mark came into a very challenging environment and performed exceptionally well. I would strongly recommend him for any company looking to accelerate revenue.

Mark's passion for business growth and innovation is contagious. He leads by example and has a wealth of knowledge and experience in technology, product, business strategy, sales and marketing.

“Justellus helped my sales team close a $90K deal after one session to teach how to overcome objections and I have never seen the team more fired up! We then had our best month of the year. One of the fastest ROI’s ever!”

“Mark is a trustworthy mentor and leadership advisor. He provides authentic advice and a valuable perspective based on years of success and experience growing businesses. Looking at the results and Mark’s impact on growth, profitability, and utilization rates, working with him is a strategic growth investment that is very easily justified.”

“Mark’s assessment, advice, and support was invaluable during our IPO and acquisition process.”

“If you are lucky enough, you will end up with a handful of great mentors. I believe in coaching, mentorship and paying it forward. Most of my life, my mentor was my father, a successful entrepreneur whom I was able to absorb, observe and listen to for over thirty years. Most recently, there were two key people, Mark Wallace who then introduced me to Barry Libert. Both came into my life at the exact right time. EstateSpace was not where I wanted it to be or intended for it to be. This was one of the hardest times in business I have had in almost 20 years and I was struggling. What happened to me happens to a lot of people, I lost focus, exaggerated the situation and the true vision was lost in the clutter.They helped me get back clarity, turn the business around and find success. The best part about this story is that professionally things are better, but personally my relationships have improved beyond measure and that is what life’s all about”.

"I hired Mark at a time of transition when we needed an experienced, effective leader for our sales and business development. I found myself relying on him on all matters from sales, social marketing and account team management to mentorship and training of our younger employees.  He's a person of integrity and loyalty who is well respected by peers and partners alike.”

Very simply, Mark is a superb sales leader with a clear understand of social technologies and it's impact on sales and marketing, the importance of data, and using the social web to build customer relationships to drive growth.
