What It Takes to Build an Aviation Aftermarket Business

How curiosity, responsiveness, relationships, and better systems turn experience into sustainable growth

Aviation aftermarket companies often begin with expertise.

Someone understands aircraft parts. Repair. Engines. Sales. Technical records. Asset management. AOG support. They learn a corner of the industry deeply enough to recognize where customers struggle and where an opportunity exists to help.

Turning that expertise into a durable business requires another set of skills.

A founder has to understand the customer well enough to identify the right problems, create a meaningful reason for customers to choose the company, build relationships that extend its capabilities, and eventually develop systems that allow other people to deliver the same value.

Delphine Kennedy’s path through aviation offers a useful example of that progression.

She grew up around aircraft maintenance through her father, began working summer jobs in the industry as a teenager, spent time on an AOG desk, and later worked across brokerage, dismantling, OEM operations, and surplus trading before founding DBK AERO. Each environment gave her a different view of how the aftermarket works—and of where it could work better.

Her experience points toward a larger lesson for anyone building or growing an aviation business:

Stay close enough to the work to understand the problem. Stay close enough to the customer to understand why it matters. Then build the people, relationships, technology, and systems that allow you to solve it repeatedly.

Learn the Business Close to the Work

Some of the most useful commercial knowledge develops far away from a sales presentation.

Early in her career, Kennedy would find reasons to go into the warehouse and see the components she was selling. She wanted to understand what the parts looked like, how they differed, what they were worth, and how they fit into the larger aircraft support environment.

That curiosity matters.

Aviation contains enormous amounts of specialized information. Part numbers, conditions, certifications, interchangeability, lead times, repair options, availability, technical requirements, shipping constraints, and customer priorities all influence what constitutes a good solution.

The closer someone gets to the actual work, the easier it becomes to understand how those pieces connect.

Kennedy’s later moves through brokerage, dismantling, an OEM environment, and surplus trading added other perspectives. She could see the same market from the supplier side, the customer side, the large-company side, and eventually the entrepreneurial side.

That breadth creates judgment.

Someone who understands only a transaction may see a part number and a price. Someone who understands the surrounding operation can also see urgency, alternatives, documentation requirements, inventory implications, logistics, future demand, and the consequences of getting the decision wrong.

For leaders developing people in the aftermarket, that suggests an important training principle:

Give people opportunities to understand what happens before and after their piece of the process.

Let salespeople spend time around inventory. Let warehouse teams understand customer urgency. Let newer employees hear why a particular component matters. Let people follow a transaction far enough to see the operational problem behind it.

Knowledge becomes much more useful when employees can connect what they do to what the customer is trying to accomplish.

Stay Curious Long Enough to See the Real Problem

Curiosity appears repeatedly throughout Delphine’s career.

Near the end of the conversation, she describes one of the things she continues to enjoy about aviation: learning something new every day. A component, aircraft, customer, market or technical issue creates another reason to ask questions.

That mindset has commercial value.

Businesses often encounter opportunities first as recurring frustrations:

Why does this take so long?

Why does this inventory continue to sit?

Why does the customer have to repeat this process?

Why are we doing manually what could happen automatically?

Why does an otherwise good solution fail during an AOG?

Those questions help expose the distance between the current process and the outcome the customer actually wants.

Kennedy used that approach when developing DBK AERO’s Smart Revenue Partner program. She had seen airlines and other organizations carrying surplus inventory and understood the existing consignment model. Her opportunity was to determine how DBK could approach the problem differently and create a relationship that made sense for both sides.

That is a useful distinction.

Differentiation works best when it grows out of a problem worth solving.

A different logo, sales pitch, pricing structure or technology may help communicate an offer. Sustainable differentiation usually runs deeper. It improves something the customer already cares about.

In the Aftermarket, Responsiveness Is Part of the Product

One of the clearest contrasts in Kennedy’s career came from experiencing both entrepreneurial aftermarket companies and a much larger OEM environment.

Large organizations can offer tremendous resources, capabilities, institutional knowledge, engineering, infrastructure, and scale. They also operate through processes designed to support an organization of that size.

Kennedy had come from AOG environments where the operational clock moved very differently.

In the podcast, she recalls situations where an internal timeline might be measured in days while the customer’s requirement needed to be addressed in minutes.

That difference helps explain one of the aftermarket’s enduring strengths.

Smaller and specialized organizations can often organize themselves around responsiveness. Their structures may allow a salesperson, warehouse employee, technical specialist, logistics provider and decision-maker to connect quickly when an aircraft needs support.

The lesson is broader than speed.

Responsiveness means understanding the customer’s operational clock and building a process capable of working within it.

An AOG makes that obvious because every hour has consequences. The same principle applies in less dramatic circumstances. A quote delivered after a purchasing decision has already been made has limited value. An inventory recommendation that arrives after the market changes has limited value. A good technical answer becomes more useful when it reaches the person making the decision at the right time.

Companies should therefore evaluate turnaround from the customer’s perspective.

Where does an inquiry wait?

Who has authority to make a decision?

Which information has to move between departments?

What can be prepared before the request arrives?

Where can technology eliminate repetitive work?

Where does the customer still need a person?

The goal is a process designed around the decision that needs to be made.

Relationships Are Operating Infrastructure

Aviation professionals regularly describe the industry as relationship-driven. Kennedy’s experience helps show why those relationships matter operationally.

As a teenager working an AOG desk, she helped someone locate a difficult component. Years later, that person still remembered the experience when their careers crossed again.

The transaction ended. The reputation created by it remained.

Relationships in the aftermarket do far more than generate sales.

They help people find expertise. They identify inventory. They create introductions. They accelerate problem solving. They allow someone to say, “We aren’t the right solution for this, but I know who may be.”

They also carry information through a market that is global, specialized, and constantly changing.

A strong network effectively expands the capabilities of the individual company.

That creates a useful way to think about business development:

Build relationships that increase your ability to help.

Some will become customers. Others may become suppliers, mentors, employees, repair partners, logistics providers, technical resources or simply people willing to answer an unusual question when you encounter something new.

Kennedy also describes the aviation community as unusually connected. Competitors can know one another personally. Careers repeatedly intersect through companies, customers and trade shows. People remember who helped them, who followed through and who understood the urgency when something mattered.

Reputation compounds across those interactions.

Build Differentiation Around Customer Outcomes

When Kennedy created DBK AERO, she brought years of marketplace knowledge with her. That knowledge also meant entering a market full of established brokers, stockists, traders and consignment providers.

Another company doing roughly the same thing would have limited reason to exist.

The Smart Revenue Partner program grew from asking how an existing model could produce a better customer outcome.

Kennedy describes customers carrying surplus material and conventional consignment arrangements that did not fully match the approach she wanted to build. DBK developed its model around partnership and revenue generation and supported the program with systems designed to keep inventory visible and quotes moving.

One of her examples illustrates the value of proving the model through results. A prospective customer initially chose another route. Months later, the same inventory remained available. After entering DBK’s program, the material began generating orders quickly.

The broader lesson is useful regardless of the particular business model:

A customer can understand differentiation much faster when they can see the outcome it creates.

That means companies should be able to answer a few basic questions clearly:

What customer problem are we solving?

How does our approach change the existing process?

What improves because of it?

How will the customer recognize that improvement?

A differentiated business model becomes easier to communicate when the operational benefit is obvious.

Use Technology to Extend What People Do Well

DBK AERO also offers a practical example of technology adoption at a smaller company.

Kennedy wanted a two-person organization to respond to quoting activity around the clock. Manually adding enough people to provide that level of coverage would have created a very different cost structure.

So the company developed automation around the quoting process.

The technology addressed a capacity problem.

That distinction is increasingly important as aviation companies evaluate AI and automation.

The strongest question often starts with the work:

Where are capable people spending time on something technology can reliably accelerate, organize, repeat or prepare for them?

Automation can process information, generate routine responses, organize records, surface opportunities, standardize repetitive steps and keep activity moving outside normal business hours.

People remain especially valuable where the work requires judgment, trust, negotiation, empathy, interpretation, unusual problem solving and the ability to understand what a customer actually needs.

Technology and relationships therefore serve different roles.

One creates leverage.

The other creates understanding.

A thoughtful operating model uses each where it contributes the most.

Eventually, Hustle Has to Become a System

Entrepreneurs can carry an extraordinary amount of a young company themselves.

They sell. Quote. Solve problems. Build customer relationships. Check inventory. Manage suppliers. Watch cash flow. Handle marketing. Make decisions. Answer messages after hours. Fix whatever went wrong that day.

That energy helps get a business moving.

Growth eventually changes the question.

Instead of asking, How much more can the founder do?, the business has to begin asking, How can the organization consistently do this well without everything depending on one person?

Kennedy was reaching that stage when the episode was recorded.

DBK AERO was preparing to hire, expand warehouse capacity and give additional structure to a company that had grown through a small team’s direct involvement. She had also recently completed a business program that pushed her to spend more deliberate time on strategy, marketing, brand, mission and company values.

One observation from that experience is especially relevant to growing companies: sometimes leaders believe they are too busy to stop and work on strategy.

Growth makes that time increasingly valuable.

A strategy session, process review or planning day temporarily pulls people away from transactions. It can also create the structure that helps hundreds of future transactions work better.

Hustle creates momentum. Systems make momentum repeatable.

Those systems can include documented processes, clearer roles, better technology, performance measures, training, inventory controls, customer communication standards, hiring plans and decision authority.

The objective is to capture what works so success becomes teachable and transferable.

Build a Company People Can Join

A founder-led company also faces an identity challenge.

Early customers may associate the company almost entirely with the founder. The founder holds the relationships, history, reputation and instincts that helped create the business.

Hiring changes that.

New employees need to understand what the company values, how decisions get made, what good service looks like, how customers should experience the organization, and what standards the team expects from one another.

Kennedy describes wanting DBK AERO to become increasingly established as a company rather than simply an extension of herself. She also connects brand and marketing to attracting the kinds of employees the company wants as it grows.

That is another useful reframing of brand.

Brand influences customers, but it also helps prospective employees decide whether they want to participate in what a company is building.

A growing aviation organization needs people who can see a future there.

That makes culture, training, values, leadership, communication and professional development part of the growth strategy.

Invest in People Who Expand Your Perspective

Kennedy gives significant credit to mentors and other people who influenced her career.

Different leaders showed her different ways to think, manage and build. Friends and family provided encouragement. Her husband understood the peculiar demands of an industry where an AOG can interrupt an otherwise normal evening.

She now tries to provide some of that same support to other people who contact her for advice, particularly women interested in building careers or businesses in aviation.

Mentorship has practical business value because experience transfers.

A good mentor can help someone recognize a problem earlier, consider a different option, recover from a mistake faster or understand a situation they have never encountered before.

The best professional networks contain people who challenge one another as well as support one another.

For someone building a business, that may include:

customers who explain what really matters to them,

technical experts who fill gaps in the founder’s knowledge,

leaders who have already navigated a similar stage of growth,

employees who see operational problems differently,

and peers willing to share what worked—and what did not.

No founder accumulates every perspective personally.

Strong relationships provide access to perspectives that would otherwise take years to develop.

Keep Getting Closer to What the Customer Needs

The aftermarket contains plenty of complexity: millions of components, global supply chains, technical requirements, documentation, repairs, inventory, asset values, logistics, AOGs, unpredictable demand and constantly changing market conditions.

Yet a strong aftermarket business often comes back to a relatively simple discipline:

Understand what the customer is trying to accomplish and make it easier for them to accomplish it.

Sometimes that means locating a difficult part.

Sometimes it means answering seven minutes faster.

Sometimes it means helping monetize inventory that has been sitting for months.

Sometimes it means automating repetitive work so people can focus on the decisions that require them.

Sometimes the best service is connecting the customer with someone else who can solve the problem better.

Kennedy’s journey from the warehouse and AOG desk through larger aviation organizations and eventually into entrepreneurship shows how valuable those accumulated observations can become.

Experience creates the raw material.

Curiosity turns experience into insight.

Relationships broaden what a company can accomplish.

Technology creates leverage.

Systems make the work repeatable.

And throughout all of it, the customer remains the reason the business exists.

For aftermarket companies looking to grow, that may be the most durable strategy of all: keep learning, keep listening, and keep building better ways to solve the problems that matter.
