The founder
A maintenance shop that built its own tools.
Mike Brown has spent twenty-five years in aviation maintenance, twenty of them on Gulfstream airframes — from the Tay-powered GIV and G450 through the G550 to the G650 and the fly-by-wire G500 and G600. Factory-trained at FlightSafety Savannah on each of those families, he is an FAA-certificated Airframe and Powerplant mechanic and an NCATT Aircraft Electronics Technician with the NAV/COM endorsement.
Before Gulfstream there was the Marine Corps, maintaining F/A-18 Hornets. The habits it left — the checklist finished before the coffee, the discrepancy written down the moment it is seen, the work order that reads the same to the next technician as it did to the first — are the operating system of this company.
Between the two sits time at Gulfstream Aerospace and Safran Nacelles: the manufacturer’s side of the same airframes, and the powerplant side of what hangs under their wings.
Everyone else brings technology to aviation. We bring aviation into technology.
OnChain Aviation exists because the records side of maintenance has not kept pace with the work. A logbook can be lost, a page can be rewritten, and an aircraft’s value rests on paper nobody can independently check. Mike built the company to fix that from the flight line outward: do the maintenance properly, then keep the record where it cannot be quietly changed.
Since 2026 he is a founding member of the IronFleet Network and the anchor customer for IronFleet aviOS — the shop hardens the software before anyone else relies on it. Where a feature does not make the aircraft safer or its record more trustworthy, it does not get built.
What you get when you call. You get Mike. Not a service desk, not a sales engineer — the A&P who will be under the aircraft. That is a deliberate limit on how fast the company grows, and it is the reason the work is what it is.
