In a sun-drenched conference room in Tokyo, John Harris speaks with the measured confidence of someone who knows he's on the right side of a shifting industry. As chief executive of Worldwide Partners Inc. (WPI), the 87-year-old collective of independent agencies, Harris is building what he calls a "reverse holding company," where the power dynamic does not sit with the network but is fundamentally inverted.
"In 2020, we were in a reactionary mindset—things were happening to us," Harris announced at WPI's global AGM. "Five years later, everything we're doing is intentional."
That intentionality has transformed WPI into a network of 93 agencies across 50 countries, built entirely on five pillars: scale, diversification, community, collaboration, and brand equity. Perhaps most telling has been the shift in member composition from full-service traditional shops to a third now specialists. The results speak for themselves: the network’s revenue and share price have climbed steadily, collaboration between members has doubled year-on-year, and attrition of member agencies is low—a sign that agencies are staying not out of obligation, but because the network is delivering value.
Harris frames it as culture: “Agencies stay because they see value in being part of this network and they come with an ‘I want to contribute’ mindset,” he explains.
Harris reflects on his 15-year tenure at Omnicom chasing revenue targets. “At WPI, the difference is, our agencies own the network. And the network is not engineered to make money — it’s designed to make agencies better. Every dollar we make is reinvested in marketing, training, and visibility for our agencies. I’ve never had that kind of freedom before.”
He is emphatic that growth is client-driven, not arbitrary ambition. “We didn’t set out to be the biggest independent network,” Harris emphasises. “We set out to have the right footprint in the right markets.”
Korea and Japan are current focal points as clients shift spend from China, while Dubai is a geographic area of interest. Sector and capability focus is sharpening: pharma, B2B, and influencer-driven marketing are priorities, alongside specialist agencies that bring deep vertical expertise.
Holding companies have scale, capital, and centralised infrastructure. Independents have freedom, something that's harder to quantify. WPI’s structure allows agencies to act nimbly, with full attention on client outcomes rather than internal politics or principal media margins.
“At the network level, holding companies get the benefit of the doubt—a client will assume they will collaborate effectively at scale because they share a name. But in reality, many of those offices have never met or operate independently. We, on the other hand, have to prove collaboration works,” Harris says, drawing on his 15 years at TBWA.

Over the past 18 months, Harris has turned away 125 agencies that failed to meet cultural, operational, or capability standards.
“The most important piece is identifying agencies that share our ambition and commitment to collaboration. That’s probably the biggest criterion—you have to want to contribute, not just take. We look at the quality of work, capabilities, leadership team, and growth trajectory when recruiting an agency,” he explains.
Once accepted into the network, agencies can choose to be partners or shareholders. About 40% of members are shareholders.
“Every agency that joins has the opportunity to become one, and you can buy 100 shares—no more, no less. So, if you’re a 500-person agency or a 10-person agency, you both have 100 shares and an equal vote. Shareholders also approve any new agency applying for membership. This provides quality control—not only in the type and calibre of agencies, but also in ensuring cultural compatibility,” Harris says.
In practice, this translates to a rare blend of interdependence and decisions that are owner-driven rather than dictated from the top.
“I like our size, and we are not adding agencies for the sake of scale. It’s about bringing in partners who complement the existing network—fill in geographic gaps, expand capabilities, and deliver on client expectations with the best people, not the most offices,” Harris says.
What is it like on pitch day?
Collaboration is adland’s most abused word. In big networks, it’s often more aspiration than action—especially when offices sit in silos, separated by time zones and egos. Nonetheless, Harris talks about how it’s the network’s currency that's quite different from the way most networks use it.
You can see the results in a string of cross-border wins. Brand USA is the standout: WPI snatched the global media remit with a simple but ambitious goal to attract 90 million international visitors to the US by 2027. Four WPI agencies now co-lead the account across regions.
Since WPI came on board, tourism is already up 10%. The former client CMO, Staci Mellman, said, “In my first 10 months, our marketing campaigns reached 3.2 billion travellers, with 151 million completed views of three-minute-long videos—all for 80% less than platform baselines. We’ve driven more than 9 million clicks to our content and 8 million to our trip planner.”
So what happens on pitch day? Are the partner agencies together in the same room?
“For another client [under embargo], we were up against three other networks,” he recalls. “All our agencies from the US, UK, and Australia were in the room together and we were the only ones that had all countries represented in the meetings. The lead partner ran point, but everyone presented. That’s rare. Most networks’ offices haven’t even met before the pitch. Ours had been working together for weeks. It’s important to demonstrate to the client that this [synergy] is real — that this isn’t just a group of friends coming together and pretending to know each other. It’s the proof of concept for the network.”
If most networks pitch to prove the might of their scale, WPI pitches to prove its chemistry. Independents acting like a collective, not a coalition, is a small but radical inversion.
In the first 90 days of this fiscal year, WPI recorded a 44% YoY increase in shared pitches, joint projects, and co-created campaigns. A third of those collaborations were cross-capability—creative agencies teaming with media or influencer specialists within the network.
Of course, not every partnership glows with that same cooperative energy. Humans are humans; agencies can miss deadlines, egos can flare. What happens when a partner agency doesn’t toe the line?
“That’s the third time I’ve been asked that in two weeks,” Harris says, half-amused. “Usually, it’s a holding company question.”
Without a tribunal or disciplinary memo from global HQ, the fix, he says, happens the old-fashioned way.
“Collaboration is hard,” Harris says. “You can have process and shared tech, but it’s still art masquerading as science. And if something goes wrong, it’s owner-to-owner and a direct conversation. That said, we’ve never had a situation where we’ve had to remove a poor performer. We are not about enforcement. There are no referral fees or financial incentives for partner agencies to work together. The only reward is success.”

Holding companies have scale baked in. They can pour millions into AI platforms, build global media-tech stacks, and standardise workflows across continents. Independents can’t compete against the behemoths dollar-for-dollar. WPI treats that scarcity as a strength: a reason to stay nimble, curious and collaborative, where the networks are often slow and siloed.
“The network itself doesn’t invest in tech—we don’t dictate how agencies operate. Instead, we find best-in-class solutions within the network and share them,” says Harris. It’s a collective intelligence model: one agency’s AI tool for creative testing might power another’s campaign in a different market; a bespoke media stack in Seoul could quietly become the template for Sydney.
The upside is agility and cost control. Clients aren’t paying for layers of bureaucracy or markups on proprietary tools. But the trade-off is real. Shared systems can’t truly replace deep, central tech investment without outcomes (read innovation) becoming uneven. The network’s biggest strength—autonomy—can also be its Achilles heel.
Earlier in the day, that same pragmatism ran through WPI’s panel briefing on pricing, where Robin Bonn, founder of London-based Co: Definery and marketing consultant Ivan Fernandez, along with John Harris, concluded that indies should stop chasing the cheapest rate and start proving value. The best advice was for shops to not wait for the RFP to start client conversations. But building the relationship six months before procurement sets the rules to understand the client’s pain points, test ideas, and show impact. Basically, earn trust early enough to offset the scale and tech might of a Holdco.
“We throw brains, curiosity, and trust instead of money,” Harris says. It’s a noble mantra, but also a risky one. Ingenuity can only stretch so far without solid infrastructure beneath it. When a multinational client demands real-time data integration or a custom AI model, will agility lose to capital?
Meanwhile, the big networks are evolving at speed. The proposed Omnicom–IPG merger, consolidation within WPP, and Dentsu’s financial volatility are all signs of an industry under reconstruction. Generative AI has already broken the traditional pricing logic, where hours equalled value. Now, time is cheap, and critical thinking is the only real currency left.
That’s where independents might actually have the edge. They can be faster, more human, and less afraid to experiment. As Co:definery’s Robin Bonn said: “The real issue for independents isn’t pricing, it’s commerciality. Once you bring commercial thinking back into the conversation, the pricing takes care of itself.”
So the question isn’t whether independents can keep up… It’s whether they can afford not to. Can human ingenuity still win against algorithmic efficiency? Will the indie advantage—the freedom to experiment without corporate constraint—become its biggest vulnerability in an age that rewards standardisation?
Because in the end, when the networks throw money at the problem and independents throw people, only one side can afford to lose a few rounds.
