About
Dennis McMahon
30+ years in business. Not in tech—in construction, manufacturing, and operations. The messy stuff where things actually get built.
I started building AI platforms because the tools I needed didn't exist. Now they do. And I'm sharing them with others who have the same problems.
The Journey
Construction & Modular Expert
Started in construction over 30 years ago. Became a specialist in modular and prefabricated building methods. Seen the industry evolve from traditional stick-built to factory-manufactured.
Global BuildtechFactory2Key Partnership
Currently partnering in Factory2Key, delivering turnkey modular homes including SDA (Specialist Disability Accommodation). This is where Checkpoint was born—I needed a project management system that actually fit how construction works.
Factory2KeyAI Platform Builder
Started using AI coding support to solve my own business problems. Then voice AI to improve customer experience. Then platforms for others. Now running Long Tail AI Studio—a portfolio of AI platforms each solving real problems.

"I don't build software because I love software. I build it because the tools I needed didn't exist."
Every platform in the Long Tail portfolio started as a problem I had—or a problem someone brought to me. I don't build features. I solve problems.
After 30+ years in construction, I've learned that the best solutions come from people who actually do the work. Not consultants who observe. Not developers who assume. People who feel the pain.
That's why I build. That's why I partner with others who have problems worth solving. And that's why I'm inviting you to join the journey.
