Asset History Report is built on Harmelo, the infrastructure identity registry that gives every mechanical and energy system a permanent record. Here's who we are, why we're doing this, and what we're really building.
I didn't start Harmelo because I wanted to build a software company. I started it because I spent years around mechanical systems inside homes and buildings, and I saw the same problems happen over and over again.
People spend thousands of dollars on furnaces, heat pumps, hot water systems, and the equipment that quietly runs their homes for years. But when something goes wrong, nobody knows the history of the system. Was it installed properly? Was it maintained? Was the warranty even registered?
Too often the answer is that no one really knows. Contractors change. Companies go out of business. Paperwork disappears. Warranty registrations never get filed.
I've seen homeowners move into a house and have to replace a furnace or mechanical system three to six months later because there was no record of work completed on it. Home inspectors do their best, but they aren't HVAC technicians, and without documentation it's nearly impossible to understand the true condition or history of the equipment.
What should be predictable infrastructure turns into a stressful and expensive surprise.
Asset History Report is the homeowner-facing answer to that problem. One permanent record of the systems inside your home, kept for as long as the home stands.

The idea behind Harmelo is simple. The systems themselves should carry their history.
Every furnace, every A/C unit, every water heater, every electrical panel gets a permanent identifier we call an HMIN. Every solar array, every heat pump, every EV charger gets one we call an HEIN. These identifiers stay attached to the equipment for life. As contractors change, as software platforms evolve, as homes and buildings move through ownership cycles, the record stays intact.
For homeowners, that means clearer visibility into the infrastructure inside your home, and fewer costly surprises. For the contractors who service those systems, it means verified credit for the work they do. For the people who eventually buy the home from you, it means they take possession of a home with a real record, not a drawer of receipts.
Most of what gets built around infrastructure data is built for institutions. Software for property managers. Platforms for portfolio operators. Dashboards for cities. All of it useful, none of it serving the person who actually lives in the home.
Asset History Report is the consumer side of Harmelo. A homeowner-owned record, priced for homeowners, designed to be useful to one person and one home at a time. The record you build is yours. It transfers with the home if you sell. It travels with you if you move.
The reason we started with homeowners isn't strategic. It's structural. The record only works if the people closest to the equipment are part of it. Homeowners and the contractors they trust are the foundation. Everything else builds on top.
Harmelo's longer-term mission is to be the persistent identity layer for physical infrastructure everywhere. The same kind of standardized identity that vehicles got, that securities got, that bank accounts got. Each of those layers made its asset class legible, priceable, and insurable for the first time. Physical infrastructure is the largest asset class still without one.
That's why Harmelo also works with home builders, housing portfolio operators, contractors, and municipalities. The record that serves you as a homeowner is the same record that, at scale, lets cities plan capital responsibly, lets insurers underwrite better, and lets builders prove the standard of care behind the homes they hand to buyers.

Three things that should never disappear from the infrastructure we rely on every day. Continuity, so the history of every system stays attached to it across every transition. Clarity, so the homeowner, the contractor, and the eventual buyer all see the same record. Control, so the person who owns the home owns the record.
That's what Harmelo restores. And that's what your Asset History Report is, in your hands.
Your founding rate locks at signup. Your record activates when your first enrolled contractor logs service to your home. Portable to any home you own as long as the membership stays current.
