From Sales Floor to CEO: Macon Stokes Built Amplifier One Stretch Role at a Time

Macon Stokes is the CEO of Amplifier, a 3PL based in Austin, Texas serving e-commerce brands for 25 years. He joined in 2006 as a sales associate and never left, working through sales, operations, finance, and a stretch as president before becoming CEO. I talked with Macon about that journey, what he learned in each seat, and how Amplifier differentiates in a market where anyone with a garage and a ShipStation account can call themselves a 3PL. Here are the takeaways.

The name is the strategy

Amplifier is named for what a guitar amplifier does: you plug in a signal and it comes out louder and bigger, with no attention drawn to the amplifier itself. A 3PL should work the same way. The brand’s signal should be amplified through the medium of fulfillment. No buzz, no feedback, no noise from the 3PL. That philosophy shapes the product. On top of the standard store, pick, pack, and ship, Amplifier built what it calls amplification: everything the team does on the floor should be controllable by the brand through the platform. His example: imagine you run your own warehouse and you see that Johnny TikTok just ordered from you. You would run out onto the floor, write a note, toss in a gift, and hope he shows it on camera. With a typical 3PL, that interruption of flow is the last thing they want. Amplifier wants it.

One big sale, then the dominoes fell

Macon arrived at Amplifier right after the company lost its biggest client. Amplifier had shipped roughly 95 percent of all the Livestrong yellow wristbands in existence, and when the foundation got a new COO, the business walked. Macon was hired to fill the hole. He sold the next big deal aspirationally, he admits. Then he saw the operation and realized the promise was harder than he thought. So he walked onto the warehouse floor and started learning: operations books, every vendor seminar at every conference, until he ended up staying on the floor and running it. That pattern repeated. He moved into finance because every operational change had a P&L impact. When the VP of finance left, he took the job. Then the company hired a new COO and a new VP of finance, freeing Macon to work alongside the CEO on scaling. Eventually both left, Macon became president, and a few years later the CEO asked him to take the top job so he could focus on product.

The hardest job nobody talks about

I asked Macon which role was the most challenging, outside of CEO. His answer surprised me: the warehouse director. The layer that sits between the executives and the floor. Everyone below has a narrow job. Pickers focus on the cart in front of them. Their supervisors focus on tempo. But the warehouse director holds the whole line: pickers, packers, receiving, the ship dock. They get a fixed pool of people, say 30 associates spread across every zone, and they cannot just add more bodies because the P&L pressure hits them first. So they make the allocation call every day, then convince actual humans to move zones. The best picker in the building is only 80 percent as good at packing, and does not want to switch. The director needs the analytical chops to plan the flow and the people skills to move the people, then adjusts when a midday client emergency rewrites the plan. “There’s no truth that doesn’t come from the floor,” Macon said, invoking the Japanese idea of genba, the real place. The people who live there do not get on podcasts.

Differentiation in a market anyone can enter

Amplifier lives in the middle market: emerging brands for whom Amplifier is the first, second, or third 3PL, and for whom every shipment matters. Twenty-five years ago, few 3PLs wanted that segment. Today, Macon says, anyone can spin one up: get a garage, get ShipStation, pay a friend for a nice website. On day one they will have perfect accuracy and on-time shipping, because day one is easy. The challenge is how a brand tells the good from the bad. He calls it the proliferation of matchmakers: wherever buyers cannot judge quality, a layer of brokers appears. They may not solve the discovery problem, but they solve the feelings problem. His answer is almost embarrassingly simple: just stick around. Every year, a new low-end competitor appears and an old one disappears. Every year, someone he met seven years ago calls to say they joined a new brand and are running a 3PL search. Time in the market is the moat.

Learning to say no

Early on, Amplifier’s selling was completely free-form. Go find someone who ships stuff and close a deal, with whatever pricing structure the brand wanted. The cost was brutal: every deal a different shape, with no institutional memory of what was sold. So over about 15 years, Amplifier flipped it: all services and prices are visible on the website, which functions as the company’s ideal client profile so prospects can self-select. But structure is not enough. Macon described an internal metric he calls “time to conniption fit”: how does this prospect react when something surprising happens in the sales process? Mature, or yelling? They said goodbye to a client just last month after the man treated Amplifier’s head of client service badly. “Not all business is good business,” as Timur put it. Macon added that when a brand says it wants a partner, it often means it wants lower prices. Brands measure margin in dollars. 3PLs measure it in cents. That gap is why they screen for how people treat the team, not just the invoice.

The skateboard guy

If you follow Macon on LinkedIn, you know him as the CEO who skateboards through the warehouse every Friday, filming himself talking logistics. His VP of finance dared him to do it 52 weeks in a row for an Amplifier-branded deck. The skateboard is older than the videos. During a low point running operations, when the work was soul-crushing, he brought in a board so he could have five seconds of fun on the straight shot from the office to the back of the warehouse. His rule: anything he cannot explain while riding in under two minutes has no business being posted. He says several people told him they only watch hoping he falls. Fair play, he says. He has not fallen yet.

Buy the platform, build the connective tissue

On technology, Amplifier’s philosophy is buy versus build, deliberately. They run Manhattan Associates Scale as the WMS. They bought an order management system early, once they understood that an order is not a shipment and a shipment is not a container. What they write themselves is everything in between: the integration code between OMS and WMS, the platform layer with client-facing APIs, and the internal operational tools. Twenty years of it. Their most effective new tool is Claude, Anthropic’s model, applied to technical debt. Reading old code, understanding past choices, refactoring outdated libraries. Macon estimates the dev team is more than 50 percent more effective with it.

What is next

Amplifier runs one 110,000 square foot warehouse in Austin, which is not where you would normally put a logistics hub. They like living there and clients like visiting. But three hours to Dallas and three hours to Houston is not enough. Physical growth means more locations. The product goal is an API that can interrupt any shipment at any time: stop it mid-Gaylord, add three items, run custom embroidery or engraving, then send it back out the door. Whatever a brand could do with its own distribution center, the API should allow.

Advice from the library

Macon’s career advice: read books, then reread them. His shelf includes Getting Things Done, The Goal (anyone in logistics owes it to themselves to read it), Fierce Conversations and its sibling Crucial Conversations, Financial Intelligence, and Throughput Accounting, which pairs with The Goal to connect constraints thinking to the financial side. If you read one and want to talk about it, DM him on LinkedIn. He is ready for book club.
