Marko Sipila

Founder of HVAC Quote — 300+ HVAC owners served; started his first agency in high school

Marko Sipila is what the AI Builder mission looks like ten years in. He started an agency while still in high school, learned performance marketing the hard way, and went on to build HVAC Quote (hvacquote.ai), which has served more than 300 HVAC owner-operators. Dennis shot conference interviews with Marko on a phone, repurposed them through the Content Factory to the HVAC Quote YouTube channel, and boosted the winners a dollar a day — the exact playbook now taught to every AI Builder.

Marko runs the Content Factory across three home-service ventures, including his concrete-coating launch venture CoatingLaunch — one filmed conversation becoming articles, clips, and ads across all of them. He is also one of Dennis’s favorite proof points that mentorship is a two-way street: they have literally run a marathon together.
