The Diamond Org: Why the Barbell Was Wrong (And What Comes Next)

I drew the wrong shape.

When I wrote The Brand Marketer’s Revenge, I handed you a barbell. Revenue Growth Engineers on one end. Brand Marketers on the other. Thin middle. I called it the future of B2B SaaS marketing, and I meant it.

I still mean most of it. But I was missing something. And I didn’t figure out what until a conversation with Yasmine de Aranda, who gave me a term I hadn’t heard before: Zero Churn Architect.

More on that in a moment. First, let me tell you where the barbell breaks down.

The barbell was built entirely around acquisition.

Revenue Growth Engineers find prospects experiencing pain right now. Brand Marketers build the reputation that makes you show up when buyers ask an LLM for the best solution in your category. Both sides are real. Both sides matter. But both sides are still fundamentally about getting new customers.

What neither end of the barbell addresses is what happens after you get them.

Here’s the part I’ve been conveniently ignoring: most B2B SaaS companies are running their acquisition motion full speed into a leaky bucket. They’re spending like hell on the left side of the barbell while the right side drains. CAC keeps climbing. CROs cycle out every 18 months — not because they’re bad at their jobs, but because the targets they were handed weren’t mathematically possible to hit in the first place. Nobody asks that question in the boardroom. They just set the number and hire someone to chase it.

A barbell built on acquisition doesn’t fix that. It accelerates it.

I met Yasmine at a dinner table full of CXOs. She had just started working with the team at Winning by Design, helping them build a new practice they call Growth Guidance. She also recently called herself — and I’m crediting her here because this is entirely her term — a Zero Churn Architect.

When she said it, I immediately asked if I could use it. She said yes.

Here’s how she defines it, in her own words: it’s not about reducing churn. It’s about identifying who your ideal customer actually is — through product — and then bringing that knowledge back into sales and marketing. That’s the missing piece. Most companies start with sales and marketing and treat product as a separate universe. Zero churn architects start with the full customer lifecycle and work backwards.

The framework that underpins her work is the Winning by Design Bow Tie — if you’re newer to Cannonball, I wrote about it in our SPICED + Cannonball GTM post. The short version: the Bow Tie maps the entire customer lifecycle as two triangles facing each other. The left triangle is everything before a customer signs — awareness, consideration, decision. The right triangle is everything after — onboarding, retention, expansion. Most SaaS companies obsess over the left triangle and sleepwalk through the right.

Winning by Design built a methodology that treats the right side as seriously as the left. Growth Guidance — the practice Yasmine is helping build — goes a level above that. It asks: given where you are right now, given your stage, your product, and your market, what is the mathematically correct way to grow? Is acquisition your lever? Expansion? Retention? And how far are you from your aspirational target if you keep pulling the wrong one?

Yasmine described a CEO who walked into a meeting and said: here’s our North Star, $100 million ARR. Winning by Design ran the math. The gap between where they were trending and where they wanted to go was enormous. More importantly, the path they were on — acquisition-first, always acquisition — wasn’t going to close it. The lever they needed to pull was expansion. Their existing customers were sitting on untapped value. The company didn’t have a pipeline problem. It had a growth design problem.

That’s what a Zero Churn Architect sees that the rest of us miss.

So I’m scrapping the barbell. Here’s the new shape: a diamond.

At the top is the gap. Not a person. Not a role. A number. The delta between where your board wants to go and where you’re actually headed if nothing changes. This is the governing math of the whole system. Everything else in the diamond exists to close it.

On the left is the Revenue Growth Engineer. This is the role I’ve been teaching on Cannonball. They find prospects experiencing pain right now using public data most competitors don’t know exists. They build campaigns so valuable prospects would pay to receive them. They move fast. They use AI to do the work of three people. They’re not support staff for your demand gen team — they ARE your demand gen team.

On the right is the Brand Marketer. This is the role we killed a decade ago and are now desperately trying to resurrect. As LLMs reshape how buyers research, brand presence matters in ways we couldn’t measure before. Getting your executives published matters. Thought leadership that shapes the category conversation matters. Reputation matters. The LLMs are measuring it for you now.

At the bottom is Sales. The human conversion layer. Relationships, qualification, closing. Not going away. Just better supported than before.

In the center — and this is the key — is the Zero Churn Architect. They’re not the thin middle I waved off in the barbell. They’re the governing intelligence of the whole system. They see across product, customer success, sales, and marketing simultaneously. They’re the ones who look at the board’s aspirational target and say: okay, here’s the gap, and here’s which lever we actually need to pull right now to close it. Sometimes that’s acquisition. Sometimes it’s expansion. Sometimes it’s retention. Almost never is it “more of everything.”

The center doesn’t report to the left. It doesn’t report to the right. It holds the math accountable.

Three things are converging that make this structure necessary today, not in three years.

First, AI-enabled acquisition is becoming table stakes. Revenue Growth Engineering is real and it works — I’m seeing 4-10X reply rates with clients every week. But markets catch up. The companies doing this in 2026 have an edge. By 2028, everyone will have figured out the basics. When that happens, differentiation shifts. Who you acquire matters less than what you do with them after.

Second, LLMs are reshuffling brand presence in ways that reward the long game. Here’s a data point that stuck with me from Yasmine: Winning by Design is now finding new clients through ChatGPT and Claude referrals, not search. A firm whose entire methodology is about the full customer lifecycle — retention, expansion, compounding growth — is being discovered because AI surfaces holistic thinking. The Brand Marketer’s Revenge is already playing out in real time.

Third, the era of growth at all costs is over and the math is brutal. In a zero interest rate environment, you could burn cash on acquisition indefinitely and call it a strategy. That world is gone. Every quarter you run acquisition-first without a governing model for the whole lifecycle is a quarter your CAC climbs and your expansion revenue sits unrealized.

The companies that win the next five years aren’t just great at finding prospects. They’re great at knowing which lever to pull, when, and how hard. That’s the Zero Churn Architect’s job.

I’ve been teaching one corner of the diamond.

Revenue Growth Engineering is real. It works. I’m going to keep teaching it, because there are thousands of growth leaders who still need to modernize their acquisition motion before they can think about anything else.

But I’ve been writing about the org of the future while ignoring two-thirds of it. I called it a barbell because that’s what I could see from where I was standing.

Yasmine de Aranda handed me a better shape. Credit where it’s due.

The diamond is the org of the future. A Revenue Growth Engineer who can find and convert. A Brand Marketer who builds presence before the buyer knows they’re looking. A Sales team that closes. And in the center, someone whose entire job is to see the gap, understand the math, and decide what the organization actually needs to do next.

Figure out which point you’re building. Then figure out who’s sitting in the center.
