Zymbly

The copilot for aircraft maintenance

Zymbly gives aircraft maintenance technicians a voice-first AI copilot. Mechanics describe a fault, get an answer, order the part, dictate the resolution, and watch the compliance documentation write itself. Less admin. More aircraft in the air. Built by people who've spent careers in hangars.

The Problem

The hangar runs on brilliance. The paperwork runs on paper.

There is a plane at a gate in Atlanta. A technician found a fault. The fix itself takes twenty minutes. But first he needs to search tens of thousands of manual pages to confirm the procedure. Then he needs to cross-reference three disconnected systems to find the right part number. Then he needs to produce compliance-grade documentation - formatted correctly, referencing the correct regulatory standard - because if the paperwork is not perfect, the aircraft does not fly.


One hour later, the gate is still occupied. The airline is burning money. The passengers are grumbling. The technician - who trained for years to work on complex machinery - spent most of his shift doing admin.

This is not an edge case. It is the standard operating procedure for an industry that moves 4.5 billion passengers a year and still documents every bolt on paper. Aviation is one of the most technologically advanced sectors in human history. It is also one of the least digitized, at the operational level where it counts most.

"It takes me 5 minutes to change a bulb, but 45 minutes to do the paperwork."

- A line maintenance technician. Heard by Zymbly every day.

That sentence - a small, exasperated complaint from one person on a cold hangar floor - is the premise of an entire company. Zymbly was built to make it obsolete.

The solution is a voice-first AI copilot. A technician says what the problem is. The system pulls the answer from the relevant manual page, historical maintenance records, and local procedures. It surfaces the correct part number, confirms availability in inventory, and orders it. The technician speaks the resolution. The AI converts those words into a compliant, formatted maintenance record - checked against regulatory standards, ready for the QC auditor. No typing. No reformatting. No hunting.

The result: the people who came to fix aircraft get to fix aircraft. The airlines stop losing gate time to admin. And a sector staring at a 43,000-person workforce shortage gets a way to do more with the people it has.

The Team

Three people who built planes, ran airlines, and wrote AI - then put them all in the same room.

CEO & CO-FOUNDER

Ben Jacob

Ben spent years inside airlines helping carriers drag their operations back from pandemic chaos. He knows how badly things break when maintenance capacity gets stretched. He then moved to Multiverse - backed by Google Ventures, General Catalyst, and Index - where he led Applied AI and learned what it takes to make machine learning do real work inside large, regulated organisations. Zymbly is where operational urgency meets technical depth.

CTO & CO-FOUNDER

Azmat Habibullah

Azmat started hacking at 11 years old. He completed a Masters in Mathematics at Imperial College London, with research into quantum mechanics, and then spent his career building enterprise software for regulated industries. He understands what compliance actually demands - at the code level - which in aviation is exactly the kind of specificity that separates tools that get deployed from tools that stay in a pitch deck.

CHIEF CUSTOMER OFFICER & CO-FOUNDER

Robbie Bourke

Robbie spent 25 years living the problem Zymbly solves. He led design teams at Airbus. He was Head of Aircraft Maintenance at Virgin Atlantic. He then became a Partner at Oliver Wyman's aviation practice, advising carriers on operational transformation. He is the person who spent two and a half decades watching brilliant engineers bury themselves in binders. Now he ensures the product works the way a technician actually thinks - not the way a product manager imagines a technician thinks.

Three founders. One problem. Twenty-five years of combined experience on the problem they're solving.

The Product

An AI copilot that plugs into everything mechanics already use - and gets out of the way.

Zymbly is not a chatbot bolted onto a filing cabinet. It is a voice-first, deeply integrated platform that connects to the maintenance data sources that already exist - technical manuals, historical defect records, local procedures, ERP systems, and maintenance management platforms. Built from the start for FAA, EASA, CAA, and Part 145 environments. Data is encrypted, access-controlled, GDPR-compliant, and customers retain data sovereignty.

The platform was developed through a design partnership with a major global airline - meaning the feedback loop ran through real technicians with real faults on real aircraft, not user testing sessions with student interns.

Voice-First Troubleshooting

Say the fault out loud. Zymbly retrieves the right procedure from manuals, historical records, and local guidance - instantly. No more scrolling through 50,000-page document libraries while an aircraft sits on a gate.

Auto Documentation

Dictate the resolution. Zymbly turns voice notes into formatted, compliant maintenance records - referenced to the correct regulatory standard and ready for QC sign-off. No typing. No reformatting. No omissions.

Parts & Inventory Lookup

The AI surfaces the correct part number and confirms availability across connected inventory systems - before the technician walks to stores. Saves round trips, reduces wrong-part errors, and keeps maintenance moving.

Step Audit & Compliance Check

Zymbly tracks the technician's actions against the procedure and flags any critical steps not yet completed - acting as a second pair of eyes before the aircraft gets signed off. A check that doesn't get tired or distracted.

Built for the people who keep your plane in the air. Not for the people who approve budget slides.

The Opportunity

Aviation is flying into a workforce wall. Zymbly makes the wall irrelevant.

North America alone will be 43,000 maintenance technicians short by 2027. Boeing's 20-year outlook calls for 710,000 new technicians worldwide. These people take years to certify and license. You cannot solve a 43,000-person shortage by printing more job listings.


The standard response is to hire faster. It is slow, expensive, and structurally insufficient. Zymbly's position is different: instead of chasing a supply problem that compounds every year, make the technicians you already have twice as effective. The bottleneck is not headcount. It is the admin burden eating half their shift.

The global MRO market exceeds $100 billion. It is also one of the least digitized corners of aviation - an industry that has built titanium engines with tolerances measured in microns and still manages its documentation with paper binders and tribal knowledge. The efficiency gap is enormous. The regulatory motivation to close it is growing. And the labor crisis is accelerating everything.

Airlines and third-party MRO operators are Zymbly's direct customers. Their users are the line and base maintenance technicians - the people who are currently filing forms when they should be working on aircraft. The value proposition lands at a level every operations director immediately understands: reduce the admin burden, reduce gate time, reduce the risk of documentation errors, and stretch your technician workforce further without burning them out.

The Details That Matter

Five things about Zymbly you will repeat at dinner.

CTO Azmat Habibullah started hacking at 11. He completed a Masters in Mathematics at Imperial College London - research in quantum mechanics included - before pivoting to building enterprise software for regulated industries. The quantum mechanics part is decorative. The enterprise software part is load-bearing.

Robbie Bourke spent 25 years at Airbus, Virgin Atlantic, and Oliver Wyman watching brilliant engineers get buried in binders. He did not join a startup because it sounded exciting. He joined because he had lived the problem for two and a half decades and ran out of patience waiting for someone else to fix it.

The phrase that launched a company: "It takes me 5 minutes to change a bulb, but 45 minutes to do the paperwork." A real technician said this. Zymbly's entire product exists because sentences like this one kept getting repeated in every hangar their team visited.

Boeing forecasts a need for 710,000 new maintenance technicians over 20 years. Zymbly reads that number not as a threat to their market but as a description of it. Every technician you make twice as effective is two technicians. In a 43,000-person shortage, that arithmetic matters enormously.

The MRO sector is worth over $100 billion and remains one of the least digitized in aviation. Paper binders. Manual cross-references. Institutional knowledge that retires with the engineer who carries it. In an industry where a single gate delay costs an airline thousands of dollars, the gap between what is technically possible and what is operationally deployed is still remarkable.
