Welcome to My Portfolio
$40M+ in Revenue Generated. One Proven Model Created.
Welcome! I’m William Leonard, an AI-powered marketing Practitioner with over 10 years of experience scaling businesses and generating significant revenue. Unlike traditional marketing, which sticks to theory, I focus on delivering real results through robust systems. This led me to develop the ISI™ Model—a heuristic, step-by-step framework that transforms innovative ideas into revenue-generating initiatives with precision and real-world execution.
Marketing Is Simple. Execution Is Complex.
In a world where anyone can claim to be a marketer, true differentiation lies in execution. That's where I come in. Marketing is straightforward—it's about delivering the right message, to the right people, at the right time. However, mastering the execution of that simple concept requires sophisticated systems and proven strategies—that's the heart of my ISI™ Model.
Step 1 – Innovation:
I define WHAT your product/service offers and WHY it matters so that then I can strategically innovate HOW to position it to dominate the marketplace and stay ahead of the curve. 
Step 2 – Segmentation:
I understand WHO exactly your audience is and WHAT drives their behavior to craft segmented, data-driven persona stories that resonate and compel action.
Step 3 – Implementation:
I execute with precision, detailing exactly WHERE, WHEN, and HOW I'll implement campaigns to achieve maximum impact, aligned directly with your goals, using my Mario Kart Analogy.
(TLDR: The ISI Model Turns Ideas Into Systematic Growth)
Only Here For The Real-World Case Study?
Discover How My Model Translates Into Real-World Success
Each step of the ISI™ Model has been meticulously engineered to drive tangible growth. If execution were simple, every marketer would be a millionaire. Dive into this detailed case study to see how a national solar company turned an innovative idea into $20 million in revenue.
