A business jet flies by the hour. Its repair bills arrive on their own schedule. JSSI built a business around bringing the two together.
A jet can send data across an ocean while its maintenance record waits for a pen. Ultramain has spent decades closing that peculiar gap, one logbook and one mechanic at a time.
A maintenance job can finish before the paperwork does. Veryon has spent half a century shrinking that gap - and is now teaching software to spot the problems that keep coming back.
Jet Parts Engineering turned the unglamorous bottlenecks of airline maintenance into a global aftermarket platform. Its playbook is simple to describe and difficult to execute: find the part an operator cannot get, engineer an FAA-approved alternative, keep it on the shelf, and answer the phone.

Zymbly is a UK-based AI startup that builds voice-first copilots for aircraft maintenance technicians - automating troubleshooting, parts lookup, and compliance documentation so mechanics can spend their time fixing planes instead of drowning in paperwork. Backed by Y Combinator (W26) and built by a team with deep roots in aviation and enterprise AI, Zymbly targets an industry facing a global shortage of 43,000 technicians and a maintenance capacity crisis.
