Most companies don’t fail at strategy. They fail at execution=.

In this episode of Signal & Noise, Brett House and Rio Longacre sit down with Tom Amies-Cull—a seasoned operator who has spent two decades inside the most complex, high-pressure agency environments, including senior leadership roles across IPG, Dentsu, and Kinesso.

This isn’t a conversation about AdTech plumbing.
It’s about something far more fundamental—and far more broken:

How organizations actually work.
Or more accurately… why they often don’t.

Drawing from years inside the machine, Tom unpacks the uncomfortable truth behind transformation in large, matrixed organizations:
It’s not a strategy problem. It’s a coordination problem. It’s a leadership problem. It’s an operating model problem.

As he puts it: “Transformation usually fails not because companies lack strategy, but because they can’t convert intent into coordinated behavior.”

This is a candid, sometimes blunt breakdown of what actually gets in the way of change:

• Why most “transformations” are just reorgs in disguise
• How internal politics quietly kill execution
• The real reason employees aren’t change-resistant—they’re resistant to bad change
• Why strategy decks and org charts are not operating models
• How unclear decision rights create organizational paralysis
• The hidden role of middle management as the “connective tissue” of execution
• Why leadership teams say they want accountability—but often avoid it in practice

There’s a lot of industry noise right now about agencies evolving into platforms, operating systems, and AI-powered machines.

Tom brings this conversation back to reality:

Most organizations are further away than they think.

Not because the vision is wrong—
but because the underlying systems (people, incentives, culture, decision-making) aren’t built to support it.

The result?
Pockets of excellence… held together by heroic effort, not scalable design.

Everyone is talking about AI.

But Tom reframes it:

AI isn’t a technology problem.
It’s an operating model and leadership problem.

AI can accelerate planning, production, and activation—but it cannot fix:

• Fragmented P&Ls
• Misaligned incentives
• Poor leadership behaviors
• Broken decision-making structures

If those don’t change, AI just makes dysfunction happen faster.

We also explore why indie agencies and PE-backed firms may have an edge right now:

• Less structural debt
• Faster decision-making
• Clearer accountability
• Stronger focus on value creation

While legacy holdcos wrestle with complexity, challengers are moving faster—and with purpose.

This episode is about closing the gap between:

What companies say they are…
and what they are actually capable of doing.

Because in today’s environment, speed matters.
Clarity matters.
Execution matters most.

• Agency transformation
• Operating models and org design
• Leadership in complex organizations
• AI’s real impact on the industry
• The future of holding companies

…this is a must-listen.
