David Kelleher and the business of getting things moving

In December 1989, David Kelleher was at the Brandenburg Gate. He was a high-school senior, an American Army officer’s son living in West Germany, watching the world he had grown up in change its shape. The Berlin Wall had opened the month before. Years later, he would remember being there as an honor he could scarcely describe. Before there was a company to run, there was this: a young person close enough to history to see that arrangements which appear permanent can come apart.

His subsequent career offers a smaller, more practical version of that idea. Organizations have arrangements too: processes, projects, chains of responsibility, software. People learn to live with them. Kelleher helped build one business around improving how those organizations worked, then started another with a friend from college. The second venture, 4G Clinical, would attract a growth equity agreement exceeding $230 million. The first deserves a proper look before the large number takes over the room.

December at the Brandenburg Gate

Kelleher’s childhood crossed borders well before his work did. His family lived in Thailand in the mid-1970s and in West Germany from 1979 until 1990. His father was a career Army officer. Service was part of the household’s daily geography, with postings determining where the family lived and the military providing a recognizable thread between places.

He went to college on an ROTC scholarship. During those years, his father became a general. Kelleher followed his own route into the Army, completing the Infantry Officer Basic School, Airborne School and Ranger School. These are concrete details in a career often compressed into the convenient phrase “former Army Ranger.” The longer version gives the early years their due.

In a 2016 essay, he described service as a central motivation. That is his own account of what mattered to him. It also provides a useful starting point for reading a working life that would eventually include consulting, company building and community boards.

“Service to the greater good has always been what makes me tick.”

Thirteen years before the second act

At Duke, Kelleher studied biology, graduating in 1994. The degree sits beside the military training on his résumé, an early combination of academic and operational experience. Later came management consulting. By 2002, he was ready to help establish a firm of his own: ACME Business Consulting.

ACME is a splendidly unceremonious name for a management consultancy. It sounds capable of supplying either a project plan or a very large anvil. The actual work was less theatrical: helping organizations build capabilities, improve processes and manage complicated technical implementations. Kelleher founded it with partners, including Scott Demorest and Peter Lizotte.

That work puts a consultant close to the gap between a decision and its execution. A company can agree on where it wants to go and still struggle to get there. ACME’s offerings addressed the machinery in between: people, projects and processes. These subjects rarely improve a dinner party. They can occupy a business for years.

The firm was based in Portland, with offices in Seattle and San Diego. Its growth was sustained enough to earn repeated recognition: before the acquisition, ACME had appeared on the Portland Business Journal’s Fastest-Growing Private 100 Companies list in eight of the previous nine years. The consulting chapter had time to become a substantial business in its own right.

The year with two beginnings

On May 12, 2015, North Highland announced that it had acquired ACME. The financial terms were undisclosed. The announcement was specific about what would happen to the founders: Demorest, Kelleher and Lizotte would each become vice presidents at North Highland, helping shape the firm’s business in the Pacific Northwest.

The deal connected a regional consulting operation to a larger organization. North Highland emphasized the firms’ compatible approaches to working with clients and their workplace cultures. ACME had recently placed fifth on Oregon Business’s list of the 100 Best Companies to Work for in Oregon. A sale announcement naturally puts the company’s best suit on; even so, the emphasis on employees was explicit.

For Kelleher, 2015 also became the founding year of 4G Clinical. Put the two events beside each other and the résumé acquires movement. One long enterprise reached a transaction. Another began. It is possible to spend so much time admiring an exit that the next entrance passes unnoticed.

An old friend, a different business

The partner in the new venture was Ed Tourtellotte. Their relationship went back to Duke, decades before they became co-founders. Each had gone on to build businesses. In 2015, their separate working histories came together in one company.

That makes the founding relationship more interesting than a chance introduction over coffee. Friendship supplied a history; professional experience supplied something else. Kelleher brought the consulting and operating background. Tourtellotte brought experience building software systems. They were starting a new business with careers already behind them.

Partnership changes how a founder’s story should be told. A singular portrait can make an enterprise look like the expression of one person’s will. Here, the other person belongs in the frame. The friendship preceded the company, and the company gave that friendship a different kind of responsibility.

In May 2019, the two were named New England finalists for EY’s Entrepreneur Of The Year award. It was shared recognition of the business they had founded four years earlier. Finalist is the precise word: an award’s distinctions should survive their journey into a biography. There is enough interest in the partnership without giving either founder an extra trophy.

A number with a purpose

On June 29, 2021, 4G Clinical announced an agreement to receive more than $230 million in growth equity from Goldman Sachs Asset Management. The stated uses included global expansion and meeting growing demand for the company’s products and services.

Money on that scale attracts the eye. It can also flatten the story around it. This was company financing, with a stated business purpose, arriving roughly six years after the venture began. It belongs to the history of the organization Kelleher and Tourtellotte were building.

The geographical ambition was already visible. The company was headquartered in Wellesley, Massachusetts, with offices in Europe and Asia. Kelleher’s public biography, meanwhile, placed him in Portland. His working story connects a Pacific Northwest consulting background with a company operating across several regions.

The international footprint gives the funding announcement a setting. Expansion means more than adding a new place to a list: it brings the recurring organizational questions of coordination, capacity and consistent delivery. These are familiar subjects in a consulting career. At a growing software company, they become the founder’s own operating concerns.

Permission to question the process

Before that financing, 4G Clinical had attracted attention for its workplace. In July 2020, it placed eighth on Fast Company’s Best Workplaces for Innovators list. A ranking fixes a moment in time. This one provides a dated milestone in the company’s early development.

The company’s description of its culture emphasized open communication, collaboration and repeated feedback from customers, users and staff. It also described hiring talent wherever people lived. Those are operating choices as much as recruitment language: who gets heard, how information reaches the product and where a team can be assembled.

For a former soldier, the invitation to challenge established practice makes an interesting pairing with the earlier training. The company encouraged employees to question familiar ways of working. Order and curiosity had to share the office. That tension gives the culture discussion more substance than a list of pleasant adjectives.

Recognition continued in a different register in February 2022, when 4G Clinical ranked sixth on the Vet100 list of fast-growing veteran-owned businesses. Kelleher’s Army background had become part of a business milestone. In May 2023, he appeared among the Portland Business Journal’s Executives of the Year. The city from the ACME years remained part of the story.

The work after the milestones

By January 2026, Kelleher’s public conversation had turned to the practical use of artificial intelligence and the need for adaptable software. His approach emphasized applications to actual business problems and continued human checking. The language was operational: where can a tool help, and what still needs oversight?

That emphasis fits the questions running through the earlier career. A process can be improved. A technical system can be made easier to change. A company can grow while having to keep its daily work coherent. The achievement is in getting those decisions to hold together after the announcement has passed.

The civic part of his biography offers another view. Kelleher has served on boards including Janus Youth Programs, Greater Portland, Inc., Junior Achievement and Home Forward. These affiliations place his working life alongside local organizations concerned with opportunity, community and housing. The founder title occupies only part of that record.

Return to the teenager at the Brandenburg Gate and the scale changes again. That December scene belongs to a public upheaval. The later career belongs to the quieter world of projects, partnerships and businesses. Both make room for the possibility that an existing arrangement can change. Kelleher’s contribution has taken a practical form: find people to work with, build an organization and keep asking what is holding the work up.
