What keeps (or should be keeping) the top performing HoldCos awake at night? Well, it's not each other. It's these three things:
Platforms working to disintermediate their relationships with clients;
Clients inhousing more of the marketing value chain, emboldened by technology; and
BrandTech.
Yes, BrandTech. A $4 billion private company working with 8 of the world's top 10 advertisers proving something the industry hasn't fully grasped: survival in the agency business now depends on being precisely the right size. Not too small. Not too large. Exactly right.
While many marketing leaders have never heard of BrandTech Group, they've heard the fairytale. The porridge too hot. The porridge too cold. The porridge just right. The marketing services industry is splitting into the same three zones, and only two are habitable and the third is a slow and certain death.
Traditional holding companies are too hot. WPP: 74,900 employees burning through overhead costs that can't be justified by capabilities delivered. Quarterly earnings pressure forcing margin optimisation over long-term transformation. Legacy infrastructure creating friction costs that compound into strategic paralysis. Every decision gets filtered through quarterly optics, Wall Street scrutiny, and bureaucratic coordination that slows execution to the point of irrelevance.
Small boutiques are too cold. Fifty employees with brilliant creative but no platform capabilities. Project-dependent revenue creating existential anxiety when major clients churn. No proprietary technology because they can't fund multi-year platform development. Enterprise clients won't trust mission-critical work to agencies that might not exist in 18 months. Talent retention collapses when recession hits and project revenue dries up. Scale limitations mean no direct platform partnerships, no enterprise contracts, no ability to make decade-long technology bets.
BrandTech Group sits at $4B valuation with 7,000 employees, $1B revenue, and portfolio companies that span the full marketing technology stack. Not too hot. Not too cold. Just right.
The Goldilocks Zone: Where BrandTech Lives
Large enough for platform partnerships. BrandTech's portfolio companies collectively spend enough on Google, Meta, Amazon, and TikTok to warrant direct partnerships. Not reselling platform capabilities. Not using self-serve dashboards. Direct API access, priority support, custom feature development, and early access to platform capabilities that smaller shops won't see for 6 months. Jellyfish created "Share of Model" tracking brand perception in Gen AI systems because they have technical relationships that enable building on platforms, not just buying from them.
Large enough for proprietary technology. Pencil has produced millions of ads using AI-native production systems. That's not a boutique creative team scaled up. That's proprietary technology requiring multi-year investment and 50+ engineers. The economics only work at portfolio scale where technology costs get amortised across multiple client bases. Small shops can't afford this. Large holding companies have competing agency brands that prevent unified platform investment.
Large enough for enterprise clients. Microsoft, Google, Unilever, LVMH, TikTok, and PayPal aren't working with BrandTech because they're "giving independents a chance." They're working with BrandTech because the capabilities, scale, and technical sophistication meet enterprise standards. Eight of the world's top 10 advertisers means enterprise procurement teams evaluated BrandTech against traditional options and chose them based on capability delivery and cost structure.
Large enough for strategic acquisitions. BrandTech bought Jellyfish when digital agencies struggled in 2023. They bought Oliver to capture the in-housing trend rather than fight it. They bought Pencil for AI-native production capabilities. Private companies with patient capital can acquire strategically when assets are mispriced. Public companies face activist investors questioning why they're making acquisitions when margins need defending.
But small enough to stay agile. Seven thousand employees is enterprise scale without enterprise bureaucracy. Decision cycles measure in weeks, not quarters. No coordination across 100 competing agency brands. No quarterly earnings pressure forcing margin optimisation over transformation investment. No legacy infrastructure requiring committee approval for technology changes. That agility compounds over time as markets move faster.
Small enough for unified technology. BrandTech's portfolio companies operate on integrated technology stacks. Oliver's in-housing infrastructure connects to Jellyfish's digital capabilities connects to Pencil's AI production connects to Mobkoi's programmatic execution. That integration is architecturally possible at 7,000 employees. It's politically impossible at 75,000 employees across 100 legacy agency brands protecting their P&Ls and technology choices.
Small enough to avoid quarterly pressure. Founder David Jones, former Havas Global CEO, answers to investors who funded him specifically to disrupt holding companies over 7-10 years. No quarterly analyst calls. No earnings pressure. No activist investors threatening proxy fights. Strategic decisions optimise for 5-year outcomes, not next quarter's margins. That changes everything about transformation investments, technology bets, and acquisition timing.
Small enough for talent density. Traditional holding companies employ thousands of people whose roles exist to coordinate other people rather than deliver client value. BrandTech employs 7,000 people doing actual work—platform expertise, technical capabilities, client service. Higher talent density means lower overhead per dollar of revenue. That efficiency enables 30-40% cost advantage while maintaining capability parity.
This is the zone. BrandTech found it, built for it, and now dominates it.
How BrandTech Masters the Zone
Fast Company named them Most Innovative Companies in March 2025 - to be clear, not "most innovative advertising company" but competing with technology companies. The recognition came specifically for GenAI applications and ethical AI frameworks. While traditional agencies announce partnerships licensing someone else's AI, BrandTech builds proprietary AI and gets recognised alongside actual technology companies.
The portfolio structure proves mastery. Oliver doesn't fight in-housing, they enable it profitably as the world's largest in-housing provider. When sophisticated marketers bring work internal, Oliver provides infrastructure and expertise that makes it work at scale. Jellyfish went from startup to £400M revenue being purely digital with no legacy print, no TV buying, just platform-native digital execution. Their "Share of Model" platform tracks brand perception in GenAI systems, positioning for AI search before others saw it coming.
Pencil represents AI-native production at industrial scale with millions of ads for 5,000+ brands. That's not traditional creative scaled up. That's different economics enabled by building for AI from scratch. Mobkoi provides programmatic and analytics with direct platform relationships, not reselling capabilities with markup.
The portfolio has zero heritage creative agencies winning Cannes, zero legacy TV operations defending margins, zero siloed agency brands competing for clients. Everything is platform-native, digital-first, built specifically for 2025 marketing reality.
The Three-Way Split
The industry isn't consolidating. It's bifurcating into two winning zones and a death zone
Zone One: Integrated giants. Publicis with technology platforms and Epsilon's first-party data. Accenture with transformation consulting and enterprise integration. Deloitte and PwC with C-suite relationships and systems integration mastery. These companies win through proprietary technology justifying premium pricing and enabling outcome-based models. When you control data, creative, media, and measurement, you price on business results rather than billable hours. Building competitive position here requires $4B+ acquisitions and 5-year integration timelines. But once built, the moats are defensible.
Zone Three: Goldilocks specialists. BrandTech with $4B valuation and $1B revenue. Stagwell with public-but-specialist portfolio. Independent specialists amplified by AI. These companies win through platform-native capabilities, private capital advantages, and agile structures that can't exist at massive scale. They're not trying to be integrated giants. They're proving integration isn't the only path to enterprise clients. Building competitive position here requires right-sizing deliberately and resisting growth that pushes you into danger zones.
Zone Two: The dying middle. Traditional full-service holding companies without technology moats. Large enough to carry massive overhead. Not large enough to compete with integrated giants who've invested billions in platforms. Not agile enough to match specialist speed or cost structures. Result: 22,000 agency jobs lost in 18 months, concentrated here. The middle isn't transforming. It's disappearing.
The Client Experience Transforms
BrandTech works with 8 of the world's top 10 advertisers. This deserves emphasis. Not mid-market brands. Not risk-taking startups. Enterprise-scale companies with sophisticated procurement, demanding standards, and multiple agency alternatives.
The pitch conversation differs fundamentally from traditional agency beauty contests. No global office tours. No Cannes Lions trophy case presentations. No heritage storytelling about agency founders from 1960s advertising. Instead: capability delivery timelines, cost structure advantages, platform partnership depth, and technology stack integration.
Traditional agencies pitch heritage and awards. "We've been doing this for 60 years. We've won 47 Cannes Lions. We have 200 offices across 80 countries." Goldilocks specialists pitch speed and structure. "We can deliver in 90 days. Our costs are 35% lower. We have direct technical partnerships. We built this platform that does what your holding company agency can't."
Traditional agencies sell coordination across siloed brands. "We'll bring together our media agency, creative agency, data agency, and digital agency." Goldilocks specialists sell integrated technology stacks. "Our platform connects creative production, media execution, and performance analytics in one system you can access."
Traditional agencies justify overhead as "global capabilities." Goldilocks specialists prove lower costs deliver more value. The math is simple: 30-40% cost advantage with equivalent capabilities means you can do 40% more with the same budget or maintain current activity at 30% lower cost.
The Uncomfortable Truth About Size
The question isn't "big agency or small agency?" That's the wrong framework for evaluation.
The question is: "Does my agency partner sit in the Goldilocks zone where structural advantages compound, or are they trapped in danger zones at either edge?"
BrandTech Group proves the zone exists and thrives. $4 billion valuation. $1 billion revenue. 8 of world's top 10 advertisers. Fast Company Most Innovative recognition.
The fairytale is real. The porridge too hot burns traditional holding companies trapped by quarterly pressure and legacy infrastructure. The porridge too cold leaves boutiques vulnerable to revenue concentration and platform access limitations. The porridge just right creates structural advantages most marketers haven't recognised yet.
Many marketing leaders haven't heard of BrandTech. But their competitors have. Enterprise clients are discovering that specialists in the Goldilocks zone deliver capabilities matching integrated giants at cost structures traditional agencies can't approach.
Market share shifts quietly before industry notices. Structural advantages compound gradually, then suddenly. By the time trade publications cover the trend, the window for early advantage has closed.
What's next for them? My prediction is that they are going to crack the upstream application of AI to the marketing value chain. As I have written previously, too much investment is happening in the last mile of tactical execution, with very little in strategy, innovation, creativity and insights even now. Watch for what BrandTech does in this space.
The zone exists. BrandTech found it. Smart CMOs are discovering alternatives to traditional agency relationships that looked inevitable until recently looked obsolete.
