The Operator Today

What he is building, right now

Dirk Buikema runs Hyperwear, the Austin company he founded in 2011 to answer a stubborn question: why does training equipment have to be hard, ugly and unkind to the joints that use it. Today he is its founder, CEO and chief inventor, and the brand sells a catalog of gear that mostly did not exist before he drew it up. The Hyper Vest adjustable weighted vest. The SandBell, a sand-filled disc you can press, slam, swing and throw. The SteelBell. The Hyper Ruck rucking backpack with its FlexLoad plates. The Hyper Rope weighted battle rope.

The company is small on purpose. It runs lean and direct-to-consumer, selling through its own Shopify storefront and Amazon, with a staff measured in double digits rather than hundreds. That structure is the strategy. It keeps Buikema close to the product and close to the customer, and it lets a fitness brand built around durable goods grow without the bloat that usually comes with scale.

In 2025 that approach earned its loudest validation yet. Hyperwear appeared on the Inc. 5000 list of America's fastest-growing private companies for the first time, citing 85% revenue growth between 2022 and 2024. "Landing on the Inc. 5000 is validation that mission-driven innovation resonates," Buikema said. The mission is four words long and printed on the company's gear: Get Strong for Life.

"Innovation matters most when it improves the way people actually train."

That sentence is the whole philosophy in one line. Buikema does not chase features for their own sake. He builds gear around how athletes, coaches, tactical professionals and ordinary people genuinely move, and he is willing to wait for a design to be right rather than first. The result is a portfolio of patents and a category of soft, throwable, adjustable equipment that competitors have spent years trying to copy.

The Long Way Around

An anthropologist, a lawyer, an inventor

Most fitness founders come from fitness. Buikema came from almost everywhere else first. He studied anthropology at the University of Pennsylvania, then took a law degree at Suffolk University Law School. He worked as an investigator, a technology attorney at Codex, and a corporate attorney and strategy director inside Motorola's worldwide manufacturing operation. When Freescale Semiconductor spun out, he ran strategy and business development there too.

It is an unusual resume for a man whose products you slam against the floor. But the through-line is visible once you know to look for it. Strategy people ask what a market actually needs. Patent attorneys think in claims and durability. Anthropologists watch how people really behave rather than how they say they do. Put those three habits in one person and point them at a dumbbell, and you get a company built on noticing what everyone else accepted.

The personal thread runs deeper than the professional one. Buikema's interest in training traces back to childhood physical therapy, after he tore an ACL during a Little League practice when his foot caught in a hole as he chased a pop fly. Rehab gave him an early, lasting education in how the body rebuilds itself, and in the gear used to do it. Decades later he founded CATZ Sports Training & Physical Therapy in 2005, and in 2011 he started Hyperwear in Austin.

Dirk Buikema, on modeling a 60% tariff with AI before raising prices
The Strange Specifics

Three things worth knowing

The pop fly that started it all. A torn ACL in Little League, a foot caught in a hole, and the long rehab that followed gave a young Buikema his first close look at how bodies break and rebuild. The fitness company came decades later, but the curiosity started in physical therapy.
The marathon headshot. Hyperwear's official portrait of its founder was not taken in a studio. It was shot at a photo stop mid-run, during the Walt Disney World marathon. A fitness founder who actually finishes the races is rarer than it sounds.
The lawyer who let a chatbot price his vests. When tariffs threatened margins in 2026, Buikema did not guess. He handed ChatGPT his full price list, history, margins and competitor data, stress-tested a 60% tariff scenario, and used the model's projection of a roughly 5% net revenue gain to set prices. The strategist never really left.

Innovation matters most when it improves the way people actually train.
