Walker Mattox on Curiosity, Hiring Problem-Solvers, and Building Gray Solutions

Open on YouTube ↗
Overview

In this podcast episode, host Chris talks with Walker Mattox, CEO of Gray Solutions, a systems integrator that Mattox founded as a sister company to Gray Construction. The conversation covers how the business began, why Mattox treats curiosity as the defining trait of the company's people, how they hire, what Mattox sees as the pressing challenges facing manufacturers, how to manage the risk of new technology, and the thinking behind the company's recent rebrand around the slogan "let curiosity lead." Mattox's recurring position is that the company's growth came from finding curious people and pointing them at hard problems, not from anything Mattox did personally.

An Origin Story That Started on Vacation

Asked where this conversation would happen over a drink, Mattox named a waterfront spot in South Florida they like to visit. It is also, they said, where Gray Solutions got its start "in a very weird way."

In September 2017, Gray Construction was in the middle of a large pork processing startup for Clemens Food Group, a multigenerational family-owned business in Pennsylvania. Mattox joked that all startups go perfectly and offered a "million dollar check" to anyone who has the solution to a flawless one, but this startup had real challenges. Mattox got calls from several people at Gray, finally including Stephen Gray, asking them to leave their South Florida vacation and go work in a freezer on an AS/RS (automated storage and retrieval system). Mattox said no four or five times, then went up on the Monday.

According to Mattox, the Clemens project tipped the scales for the Gray family. The industrial customers Gray had served for decades needed automation expertise to run their operations more efficiently, and the family decided this was too important to leave to someone else. They wanted to "control our own destiny." About two months later, Stephen Gray asked Mattox to start a business doing this work. Among the names considered was "Grayntegration," which Mattox is glad did not survive.

The story came full circle the following Christmas. Mattox was back at the same restaurant with family and saw a Hatfield pork chop on the menu. Hatfield is one of the Clemens brands, so Mattox ordered the product made at the plant they had helped start up. They described this as the best part of working in food: seeing the product in the world, and taking it as a sign that some things are meant to happen.

What "Let Curiosity Lead" Means

"Let curiosity lead" is the company's new slogan, part of its rebrand. Mattox explained how the company arrived at it. As the business grew and brought people in, leadership tried to define what makes a "Solutioneer," the company's name for its people. Mattox kept producing complicated answers and long lists before settling on something simple: they are all curious about the industries the company serves and the technologies they can provide.

Mattox argued that curiosity is what makes those people special, why customers come to Gray Solutions, and why the company does good work for them. The team is not satisfied with "it's always been done this way," and asks what else could be done instead. Letting curiosity lead, in Mattox's words, means following a thread, pulling on it, and running it down, even when that means going down a rabbit hole. Mattox added that rabbit holes can be fun, and joked that "curiosity killed the cat" may be backwards, since cats get nine lives.

A "Recovering Serial Entrepreneur"

Mattox describes themself as a recovering serial entrepreneur. They grew up around a small family business, since their father was an auctioneer and real estate broker, and had the business "bug" early without knowing what to do with it. They tried IT work and started a marketing firm before falling in love with automation and controls.

The "recovering" part, as Mattox explained it, is that they found a home that lasted. Gray Solutions had started five years earlier, and Mattox had worked around the automation space in some form for almost nine years, which for them counts as a long-term job. At the time of recording, Mattox was on site at a customer startup with the team, which they called the fun part of the work.

Why a Standalone Company Instead of a Division

Asked what finally made them say yes, Mattox gave several reasons. Having worked with Gray Construction on projects for years, Mattox had seen the need firsthand. Stephen Gray also did not want a division inside the construction company. He wanted a standalone business that could serve customers before, during, or after a construction project.

Gray, founded in 1960 in Kentucky, offered a stable, mature, family-owned partner with a good reputation, which Mattox could pair with their own ambition. The values also fit. Gray Solutions adopted Gray's three core values: putting safety and quality of life first; being customer and relationship driven; and treating others the way they want to be treated, where everyone is welcome and respected. Mattox said the simplicity of those values was a big attraction.

Mattox also admitted a "selfish" reason. They did not have to build health insurance, retirement benefits, or payroll systems from scratch. When the company started, Mattox told Gray's chief people officer, Sue, that they might grow to about 10 people in five years. Two years in, Sue called to say they needed to talk about those projections.

"I Didn't Do Anything": Growth Through People

Chris noted that Gray Solutions had become one of the 20 largest systems integrators in the U.S. according to Control Engineering, in roughly five years. Mattox's answer was that they "didn't do anything." Instead, they found a lot of smart people to do the work. Mattox called this a lesson many people learn too late and that they were lucky to learn early.

Mattox acknowledged that hiring smart people and empowering them sounds easy but is hard in practice, because leaders also have customers to serve, payroll to make, and a business to keep healthy. They described their job as two things: finding smart people, and finding interesting work for them. Engineers, in Mattox's view, are "degreed problem solvers," and the leader's job is to keep those two sides in balance by continually recruiting curious people and finding complicated problems for them.

Hiring Without a Paper Ceiling

Mattox is a high school graduate with no associate's or bachelor's degree, and said the company tries hard to tear down the "paper ceiling." They are passionate about people taking non-traditional paths into roles. The company looks for people who are driven and curious.

The company's hubs use open offices with no dedicated private offices, and Mattox's desk sits in the middle of the floor. Mattox said you can tell which people will thrive with that level of transparency and collaboration. Engineering skills, degrees, and training are essential, but what makes a great Solutioneer is a willingness to keep trying things and get creative.

Mattox gave an example from that week's startup. A locked-down, custom skidded system had software that expected a temperature sensor. The software believed a sensor was there, but it wasn't, and the team had been chasing the problem. Then someone suggested simply getting a temperature sensor and plugging it in so the machine would run. Mattox said that kind of thinking is what they try to find in interviews.

Preferring Outcomes Over Spec Binders

Curiosity also shapes which projects the company pursues. When a customer hands over a binder of specifications and asks for exactly what is written, Mattox usually says it isn't a good fit. The company prefers customers who bring a problem and a desired outcome, which it then writes into the scope of work.

Mattox stressed that this doesn't mean the company ignores specifications or engineering standards. The problem, in their experience, is that on too many projects the specification becomes the focus instead of the goal. Nobody writes a specification for its own sake. Customers have business needs, and when the team truly understands and solves those, Mattox said, the projects go best and customers tend to be happiest.

Spotting a Willingness to Learn

Mattox admitted the company is still working out how to tell whether someone is willing to learn and doesn't always get it right. One signal is a "sparkle" in a candidate's eyes when they hear about an unsolved customer problem, followed by questions like "tell me more," even about working in a freezer with pork.

Mattox also said willingness to learn applies at every level. The most senior engineers can learn from interns, who may not have seen a problem before but might have a wild idea that works. They want the most senior people to also want to learn something new.

As an example, Mattox recalled interviewing the company's very first engineer in the Atlanta airport. She had spent several years on a government project and, as Mattox recounted, wanted a new challenge and something different every day. Mattox warned her to be careful what she asked for. That same week, Mattox had called her about a new problem they needed help with in a couple of weeks.

The Superpower Question

Asked for a favorite interview question, Mattox hesitated to give it away, then offered a deal: they would share it if Chris answered it. The question is "What's your superpower?" Chris said storytelling and helping others tell their stories.

Mattox said they look at everything in the response, not just the words. Sometimes it is the surprise, or whether the person has ever thought about it. Their point was that most people have a superpower, and understanding your own strengths helps you see where you fit on a team.

Mattox's own answer was communication, specifically finding simple ways to explain complex problems and fitting something complicated into one sentence. The company provides training to help technical people explain things to non-technical audiences, which Mattox considers a skill set in its own right.

Leadership as a Journey

The best leadership advice Mattox has received is that leadership is a journey, not a destination, and that the leaders you look up to are still working on themselves. Mattox believes too many people see leadership positions as a destination.

A moment that made this concrete came in a conversation with Brian, the CEO of Gray Construction, whom Mattox admires. Brian talked about struggling with how much time to spend on strategy versus tactical execution. Mattox found it eye-opening that someone they looked up to wrestled with the same questions.

One of the Gray family of companies' guiding principles is that everyone is a leader. Mattox wants people to see that they lead whether they are running a project, a team, or guiding customers toward solutions. Leadership, they said, is an action rather than a title, and like any skill it has to keep improving.

Advice on College and Career Paths

Chris asked what Mattox would tell parents whose children might not go to college, and hiring managers who weigh degrees heavily. Mattox joked that hiring managers who screen too hard on degrees should keep doing it and forward their rejections to Gray Solutions.

More seriously, Mattox described a friend and customer who was deciding whether her son should go to college, culinary school, trade school, or straight into the workforce. Mattox used to be shy about their own story and felt like an impostor. The friend scolded them over dinner for not speaking up more. Her point, as Mattox recounted, was that people constantly hear about Bill Gates and Mark Zuckerberg, but those are a tiny fraction of the world, and more people like Mattox telling their stories would make parenting decisions easier.

Mattox's advice had two parts. First, you have to like what you do every day, and they cited the saying that if you love what you do, you never work a day in your life. Second, on education, follow the path that feels right. Mattox said they have immense respect for people who complete many years of schooling, including doctors, and called their own lack of patience for it a shortcoming. The world needs diversity of thought and people from different backgrounds. What you love can also change over different parts of your life, and finding it makes you happier.

Manufacturers' Challenges: Speed, Stability, and Human–Machine Trust

Chris asked about challenges facing manufacturers in 2023, explicitly setting aside the workforce shortage. Mattox named two, with an emphasis on food.

The first is that consumer demands are changing faster. Mattox pointed out that information moves at a completely different pace, and that this is changing both how people buy and how manufacturers produce. Customers want to evolve faster, make more changes, and offer more personalized, premium products. At the same time, they must produce more products, both in SKU count and in volume. Mattox sees a tension here. Manufacturing requires strong, stable physical and digital operating platforms, which can conflict with the push to be fast and flexible and keep launching new products.

The second challenge, which Mattox called emerging, is the changing relationship between humans and machines, including robots, autonomous vehicles, and self-driving cars. Mattox framed this as a societal problem: how to get people comfortable with these machines. They compared it to the shift from horses to automobiles, when people moved from dealing with an organic animal to trusting a machine that "blows up on purpose to propel you forward," and even climbing inside it. In Mattox's view, a similar change is happening in manufacturing now, but at the pace of modern technology. That is creating real challenges in how people and companies think and invest. Mattox said they are excited to help figure it out.

Innovation Versus Invention

On why companies should embrace innovation rather than fear it, Mattox first distinguished innovation from invention. Innovation, for them, means bringing together two ideas that haven't been combined before, so it doesn't need to be new.

As an example, Mattox described meeting with a coffee customer a couple of years earlier. They explained how pet food is flavored with a particular machine and process, then asked whether the same approach could work for ground coffee. An engineer said it wouldn't work because of how coffee behaves, but added that no one had ever asked them a question like that. Mattox's point was that the engineer could have dismissed the idea, and someone else might never have raised it. Mattox's attitude was: maybe it would work, so let's see.

Mattox also acknowledged that innovation leads to failure as often as invention does, and that you can go too far. People have been burned by "bleeding edge" technology, which is why it's called that instead of cutting edge. Still, Mattox pointed to how smartphone camera technology has propelled machine vision in manufacturing. They said they meant specifically cameras, not connected workers or tablets. In their view, without investment by Apple, Google, and others in smartphone cameras, factory vision systems would be lagging, and instead they are accelerating. The warning: if you aren't innovating, a competitor is, and they'll take your shelf space tomorrow if they can.

Managing the Risk of New Technology

Mattox's first answer to managing technology risk was "test," repeated several times, both physically and virtually. Use simulation software, trust engineers to run models, and pay for a proof of principle that tests the idea at a smaller scale. That may take longer, but a partner willing to try things with you improves your chances of success in the field. Mattox noted Gray Solutions does proofs of principle for customers but said they weren't just pitching the company, since other industry partners do this too.

Mattox also cautioned against overdoing it, because excessive testing slows down the improvements you need. Proofs of principle are always small, and things change at scale. Their rule of thumb for when to move forward: find the uncomfortable moment when you think you could test more but also think you've tested enough. That, Mattox said, is when to go.

The Rebrand: Telling the Whole Story

Gray Solutions marked its fifth anniversary in January and recently rebranded. Mattox explained the evolution. In its first chapter, the company was closely tied to construction and large projects, and its logo was the sister company's logo with "Solutions" added and the colors flipped. A modified version followed later. Mattox was emphatic that the company remains closely tied to Gray. They were recording from a job-site trailer with the Gray Construction team in the next trailer.

The goal of the rebrand was to keep that connection while returning to the reason the company was founded as a standalone business: serving customers at the beginning, middle, and end of their projects, and over their lifetime. The company realized its branding didn't tell the story of what its teams do every day. The rebrand took about a year and was not a sudden decision. Mattox noted that, like any tech-minded person, the first thing they did was pick a new web platform before finding partners to help. Even in the rebrand, they said, technology came first.

On standing out among many integrators, Mattox mentioned the CSIA community and the Automation Alliance Group the company belongs to. Part of the challenge, they said, is not standing out too much, because the industry "is not ready for the Tesla of systems integration yet" and maybe never will be. The aim was to tell the story of the company's work backed by technical credibility, focusing on customer outcomes. "Let curiosity lead," Mattox noted, naturally sets up telling people what curiosity led to.

Mattox said word of mouth between customers remains one of the company's best referral sources. Many customers have secretive projects the company can't discuss, which makes storytelling important. Public-facing stories also reach potential hires who are interested in the same work, so they have to serve both audiences.

How to Get Comfortable Telling Your Story

For people who want to tell their personal or company story better, Mattox advised first understanding the story and spending time thinking about and practicing it. Instead of rehearsing in a mirror, record yourself on a phone or iPad and watch it back. Mattox joked that they would now have to listen to this podcast and critique themself. With engineers, the company recommends practicing important customer presentations with a colleague, which helps you think through the process and get feedback.

Mattox also stressed dedicated thinking time, something the company's COO, Drew, pushes them on. They shared a story from a mentor whose daughter asked for a hot dog. The mentor thought the answer was no but didn't want to say so right away, so he told her he'd think about it for a minute. Mattox's takeaway: if you can take time to think about a hot dog, you can take time to think about something complex, like telling your personal or company story.

Partners and "Customer and Relationship"

Asked what hadn't come up, Mattox added partners. Employees are critical and customers are important, but Mattox also looks for partners who help the company deliver. These include the vendors you'd expect for an integrator, such as Rockwell, as well as companies Gray Solutions partners with on project delivery and marketing partners. Mattox advised anyone building a business to find partners and invest energy in them.

Mattox pointed out that the second core value is "customer and relationship driven," not "customer relationship" as a single phrase, and relationships with partners count too. They admitted that in the past couple of years the company hadn't invested enough in partnerships, then changed course. Mattox said the dividends pay off when you "put calories into that."

Where "Solutioneer" Came From

At the end, Chris asked about the origin of "Solutioneer." Mattox described COO Drew's role as the bridge between Mattox's two jobs: making sure the company can deliver on the problems it says it can solve. A couple of years earlier, the two were thinking about how important an identity for their people would be and joking about Disney's "Imagineering." Drew suggested "Solutioneer," possibly by text message. Mattox first thought it was cheesy, then decided that it described exactly who their people are.

Every year, everyone at the company gets a baseball tee with the year on it at the company meeting, with "Solutioneer" on the back. Mattox acknowledged some people find it cheesy but said it gives employees a shared identity and helps build a team atmosphere. Mattox also enjoys it when customers ask what the word means. Mattox closed by pointing listeners to LinkedIn and the company's newly launched website, graysolutions.com, adding that as a systems integrator, the one thing the company does not accept is faxes.
