There is a particular kind of panic that arrives on Sunday evening. The clock on 60 Minutes begins to tick, the weekend contracts, and Monday starts tapping at the window. John Gatesman had a name for it: Sunday Night Anxiety. He had worked inside large agencies and on the client side, at places including Ogilvy, Ketchum, Doner, Brunner and BNY Mellon. He knew what polished advertising looked like. He also knew what it felt like when the machinery became heavier than the idea.
So in June 2006, with two young sons and a mortgage, he left certainty for an old building on Pittsburgh’s South Side. He and two partners opened an agency. Gatesman took no salary in the first year and lived on savings. A handful of local clients kept the lights on. Then SHOP ’n SAVE arrived - the first large account, the load-bearing wall of the young business, and a client that would still be there nearly two decades later.
“I wanted to build something different: a place where big ideas mattered, where the best talent actually wanted to come to work, and where clients felt like true partners rather than transactions.”John Gatesman, founder and CEO
This is the first useful fact about Gatesman: the company was not born from a new advertising technology. It was born from a complaint about how agencies behaved. The proposed fix was speed, personal attention and people who could see the whole problem. Twenty years later, that complaint has become an operating model.
The clue is usually hiding in the refusal
Gatesman calls its method “Hacking Human Behavior.” The phrase sounds theatrical; the practice is rather sober. Research the audience. Find the motivation or barrier underneath the stated one. Put strategy, creative, media, public relations, social, digital and analytics around the same observation. Then watch what people do.
The best illustration is the agency’s work for the Center for Organ Recovery & Education, known as CORE. The campaign initially focused on reciprocity - asking people to imagine that they or someone they loved might one day need a transplant. But campaign monitoring surfaced a problem. A target segment the team called “Jake” was not merely unconvinced. He was quietly disqualifying himself. Past behavior, age or health habits made him assume his organs would not be useful.
What failed first
The audience did not reject donation. It rejected its own eligibility.
The evidence changed the premise. Gatesman moved from reciprocity to myth-busting and created “No Body is Perfect,” a platform telling imperfect people that they could still become donors. The shift mattered because it answered the objection people were actually making, not the one the campaign team expected.
CORE reports that the target segment’s registration share grew faster in its service area than in neighboring organizations. Gatesman translates the outcome into more than 118,000 future lives saved and over one million future lives healed. Those are modeled public-health figures rather than bodies in a ledger, but the behavioral turn is concrete: the first message met a hidden objection, research found it, and the team changed course.
One profit center, fewer little kingdoms
An integrated agency can mean two very different things. Sometimes it means one lobby and several departments billing one another. Gatesman says it operates as a single profit center. That detail is more important than its service menu. If media does not have to protect its margin from creative, and PR does not have to defend its patch from social, the team can move money and attention toward the answer rather than the department.
That is how a firm of modest scale competes with holding-company agencies. A client can hire one team for research, identity, advertising, media planning and buying, search, PR, influencers, events and measurement. Or it can buy a narrower engagement. Revenue comes from projects and longer agency-of-record relationships; public rate cards do not exist. The more revealing commercial number is duration: Gatesman reports an average client tenure above nine years and 100 percent client satisfaction for 2024 and 2025.
The part worth copying
Consider USG, the building-materials company. Architects and contractors both care about drywall, but not in the same place or in the same way. Gatesman reached architects through trade shows, publications and LinkedIn. Installers got programmatic media on the move, YouTube, Facebook and job-site swag. Customized landing pages connected both routes. The campaign produced more than 16,000 leads - more than double the target - and nearly a three-to-one return on ad spend.
For Rochester Institute of Technology, the chain ran from brand strategy through national media and real-time reporting. Gatesman says the work increased the target audience’s perception of RIT as a national brand by 25 percent, while applications rose 8 percent and enrollment 6 percent. The point is not that every impression becomes an enrollee. It is that the agency tries to keep the brand argument connected to the business event.
Constraints make good accomplices
The Pace suburban bus brief had no paid-media budget. Gatesman made pronoun pins, used organic social and folded the idea into recruitment materials. Local television coverage carried it further. The reported result was 2.4 million earned impressions and a 30 percent increase in Facebook engagement. Cost of paid distribution: zero. The campaign later extended from LGBTQ+ Pride to Disability Pride.
For British Airways, the object was bigger and redder: a British phone box placed in busy Pittsburgh locations. When it rang, passersby answered trivia or completed small challenges for prizes. Influencers, local news and a social contest turned the prop into distribution. Gatesman reported 7.6 million earned-media impressions, more than 186,000 influencer impressions and 19.1 million in total Twitter reach. The agency gave away 125 prize bags. Here, the thing people could touch was also the media plan.
These examples reveal Gatesman’s market position. It is neither a boutique selling one craft nor a global network selling scale. It is an independent integrated shop for organizations that want one accountable team across disciplines. Its client list crosses groceries, transplant medicine, universities, transit, finance, energy and building products. The common customer is a marketing leader with a complicated audience and a result that must survive the presentation deck.
The machine only works if someone watches it
The method has conditions. Behavioral evidence needs enough traffic and time to become legible. Integration needs client access, shared goals and permission to revise an idea after launch. Earned attention needs a story that strangers find useful or entertaining. Take those away and “Hacking Human Behavior” can collapse into ordinary segmentation with a memorable name.
Nor can every constraint be charmed into free reach. Pace’s zero-dollar result depended on a visible civic moment, a simple object and news value. A routine B2B renewal will not automatically behave like Pride month. The copyable lesson is not “make pins” or “install a phone box.” It is to identify the human action that carries the message and design around that action.
Gatesman learned to keep changing at institutional scale. It acquired digital firm Quest Fore in 2014, then Noble Communications in 2017. The Noble deal expanded the agency to Chicago and Springfield and increased headcount and revenue by nearly half, taking the combined team above 125 people at the time. It joined the AMIN Worldwide and IPREX agency networks to extend geographic reach without surrendering independence. Through the financial crisis, social media, streaming, the pandemic and now generative AI, the offer kept absorbing new specialties.
By 2026, Gatesman was smaller again than at that post-acquisition peak, with LinkedIn showing dozens rather than hundreds of employees. Yet the company marked twenty years with national accounts, repeated growth recognition and an Ad Age Best Places to Work designation. Its own 2025 scorecard listed 87 percent team retention, four new national accounts and 32 industry awards. The firm had survived the dangerous transition from founder’s bet to durable institution.
There is a pleasing symmetry here. Gatesman began because its founder noticed a behavior inside agencies - the Sunday-night dread, the slow handoffs, the transactional client relationship - and decided the prevailing model was wrong. Its campaign method asks clients to make the same move: notice what people really do, not what the organization hopes they do. The agency’s first subject was the agency itself.
