Two founding programs are open now — one for contractors, one for developers and portfolio operators. Each builds the permanent record your business has never had.

// Program 01 · For Contractors

Your work, your customers, your pipeline — for life.

The Founding Contractor Program. 1,000 spots across North America. First come, first served.

You have built your business on relationships and reputation. Every service call, every install, every warranty — the work you have done is what makes your next call possible. Right now, most of that history evaporates the moment a home sells, a property changes hands, or a customer switches providers. The next contractor inherits the building. You inherit nothing.

Harmelo ends that. Every system your techs touch gets a permanent record. Every signed entry builds the kind of verified service history that follows the asset — which means it follows you. When the property transacts, the next owner sees the contractor who has been maintaining the equipment. The competitive advantage you built does not reset. It compounds.

This is how the first wave of registered contractors will be defined — and once the 1,000-contractor cohort is full, founding terms go away permanently.

// Program 02 · For Developers & Portfolio Operators

Founding Portfolio Partner Program

For developers, builders, and large portfolio operators.

Whether you are delivering 50 units or managing 50,000, every dollar allocated to mechanical and energy infrastructure deserves visibility. Without system-level lifecycle data, replacement costs arrive unplanned, capital budgets absorb surprises they should not have to, and the assets you are responsible for age without a continuous record attached to them.

Harmelo gives every mechanical and energy system across your portfolio a permanent identity and a continuous record from the moment it is registered. Small portfolio or large, the foundation is the same. The record starts the day you register and compounds from there.

Early partner terms are available now. Every portfolio is different so pricing is discussed directly. Onboarding begins immediately for portfolio operators and developers.
