About

I’m Justin Fox, an inventor, entrepreneur, and founder of Patented Labs — an R&D company built around turning real-world problems into practical products and technology. My path started in the field as a hands-on service technician, where I spent years diagnosing problems, building solutions, and learning how things actually work. That experience eventually led me from technician, to inventor, to patent holder, and ultimately to building companies around ideas I believed could be made better. Today, I’m focused on combining that hands-on engineering mindset with AI, software, and rapid product development. I’m here to build, learn, share what we discover, and connect with other people who believe the best ideas are the ones that eventually become something real.

Built in the Field, Designed to Simplify Field Service

I built BluRelay from over 20 years of HVAC field experience, starting in 2003. I saw firsthand how contractors struggle with disconnected systems, missed calls, manual paperwork, and time-consuming payroll. I wanted to bring everything together into one unified platform, using automation and AI to simplify daily operations.

I d love feedback from contractors and field service professionals: What takes up the most time in your business, and which tasks would you most like to automate? Your insights will help shape what BluRelay becomes next.

BluRelay.app - Field Service Operations, Unified & Automated

BluRelay unifies field service operations for HVAC, plumbing, electrical, and mechanical contractors. Replace disconnected tools with one platform for AI-powered call answering and dispatch, scheduling, technician tracking, payroll validation, QuickBooks integration, customer booking, safety documentation, and more. Reduce admin work, catch payroll discrepancies before payday, capture more service opportunities, and keep your office and field teams connected.

The tool that turns what you know into something you can sell.

What s the biggest challenge you face when turning your knowledge or ideas into a digital product people will actually want to buy?

I built HowToPDF to make creating ebooks, practical guides, workbooks, and lead magnets easier. I d love to hear what others struggle with most: coming up with ideas, creating quality content, designing the product, or finding customers.
