Don’t just take our word for it - listen to those whose businesses have seen tremendous growth because of these experts.

Before working with James, I had no idea where to start when it comes to getting my business properly set up and optimized as a Canadian selling to the U.S. market... And the cross-border hurdles that come along with it. Not to mention the many operational complexities of setting up and running a successful direct response supplement offer. Thankfully, James was instrumental in helping me not only navigate these complexities, but also finding the right vendors to partner with and lending his extensive network connections for key relationships. The best thing about James is his attentiveness and diligence to his clients. He never lets anything fall through the cracks. He is always available and responsive when I need his expertise on something. He always follows up with me and encourages me when I have setbacks. He is a listening ear and his coaching and mentorship has been invaluable to my journey. From merchant processing, to selecting the best tech stack, to even branding and creative, James knows it all.
