Technical Debt Becomes Growth Debt: Why Marketing Leaders Should Care

“Every shortcut eventually sends a bill.”

I heard that years ago from a product leader, and it has stayed with me ever since. At the time, it sounded like a clever metaphor for technical debt. Over the years, I’ve seen just how real that bill can be.

At a previous technology company, we saw a clear opportunity to grow down‑market. Smaller customers needed what we offered. The segment was attractive, the strategy was sound, and the commercial teams were ready.

But there was a problem.

Years of architectural shortcuts and accumulated technical debt meant the platform couldn’t be efficiently configured, priced, or implemented for that segment without heavy customization and engineering work. What looked like a compelling new market on paper turned into an almost impossible motion to scale in practice.

On the surface, it might have looked like a pipeline, positioning, or pricing challenge. In reality, it was something else: our technical debt quietly closing off an entire growth path.

CMOs are trained to look at familiar levers when diagnosing what accelerates or stalls growth: ideal customer profiles, market opportunities, competitive dynamics, positioning, pricing, and go‑to‑market execution.

But not every missed growth target is a marketing problem. Sometimes the real issue is buried in your architecture.

And one area I rarely hear marketing leaders talk about is “technical debt.”

Tech Debt Isn't Just an Engineering Problem

Technical debt is the "interest" organizations pay for shortcuts taken in the name of speed. Sometimes those tradeoffs are intentional. Startups, in particular, often choose speed over perfection because getting to market matters.

The problem isn't taking on debt. The problem is failing to manage it.

Whether it's rushed code, aging infrastructure, brittle integrations, outdated dependencies, or incomplete documentation, technical debt eventually creates friction across the business. Engineering teams spend more time maintaining than innovating. Product roadmaps slow. Customer issues increase. Costs rise.

What begins as a technology issue eventually becomes a business issue.

The impact can be significant. McKinsey's analysis found that companies with the strongest tech-debt posture achieve revenue growth roughly 20% higher than those with the weakest. Meanwhile, Deloitte estimates technical debt consumes 21%–40% of IT spending. The firm also found that nearly 60% of leaders believe 21% to 50% of their enterprise value remains trapped within their current technology and data stacks.

That's capacity that could otherwise be directed toward innovation, customer value, and growth.

Why Marketers Should Care

On the surface, technical debt feels like someone else's problem. It's not. The consequences show up in places marketers care deeply about.

Time to Market

Feature launches slip, website enhancements get delayed, integrations take longer than expected, and competitive responses slow.

When technology can't move at the pace of the market, growth opportunities are missed.

Customer Experience

Customers don't experience technical debt directly. They experience its symptoms: broken workflows, slow performance, inconsistent experiences, missing functionality, and delayed innovation.

Every interaction shapes perception, and every frustration chips away at trust. And trust is ultimately a brand issue.

GTM Friction

One of the biggest lessons I've learned over the years is that growth rarely stalls because of a single catastrophic failure. More often, it slows because friction accumulates across the system.

Marketing can't launch because new features aren't ready. Product teams can't stick to a reliable roadmap. Customer success teams create workarounds for broken processes.

Technical debt doesn't stay contained within engineering; it creates friction across the entire go-to-market engine.

Burn Rate, Growth Investment and Budget Impacts

Every dollar spent maintaining brittle systems is a dollar not invested in innovation, customer acquisition, customer experience, or market expansion.

Marketing budgets don't get squeezed only when revenue slows. They get squeezed when growing portions of the business budget are consumed by the hidden costs of keeping aging systems running.

Unchecked technical debt doesn't just compete with growth initiatives. It slowly crowds them out.

When Technical Debt Becomes a Business Problem

Business history is filled with examples of organizations that learned this lesson the hard way.

Southwest Airlines' operational meltdown highlighted the risks of deferred technology investment. What appeared to customers as a scheduling failure was, in reality, the culmination of years of accumulated technology constraints.

The lesson extends far beyond airlines. Organizations often discover that their ability to scale is limited not by market demand or strategy, but by the systems supporting the business. Growth creates complexity. Complexity exposes weaknesses. And weaknesses become increasingly expensive to fix as companies grow.

These aren't technology failures. They're business failures with technology at their root.

Companies That Invested Before They Had To

There are also examples of organizations that recognized the risk and acted early.

• LinkedIn's "Operation InVersion" became a company-wide effort to modernize systems and improve scalability before growth was constrained.

• Netflix continuously invested in platform modernization as its subscriber base expanded globally, ensuring technical limitations didn't become scaling limitations.

• Companies like Airbnb and Lyft similarly re-architected critical systems to avoid being strangled by their own success.

What these organizations understood is that technical debt is easiest to address before it becomes a crisis.

Too often, companies wait until technical debt reaches a breaking point. By then, remediation efforts can require significant budget, leadership attention, and organizational capacity. And when executives go looking for funding, growth investments are often among the first areas scrutinized.

Having spent years around executive tables where these discussions were taking place, I've seen organizations make well-intentioned decisions to address technical debt, only to undermine future growth in the process.

Marketing programs get delayed. Brand investments get reduced. Demand generation budgets get cut. Events get canceled. The result is often a healthier technology roadmap paired with a weaker growth pipeline. That's not a tradeoff. It's a warning sign.

The goal isn't to choose between platform health and growth investment. The goal is to manage technical debt before either becomes a crisis. The strongest organizations understand that modernization and growth are not competing priorities. They are complementary investments. One creates the foundation. The other creates the future.

I've seen this firsthand. At one company, technical debt had accumulated to the point where engineering teams were spending more time maintaining yesterday's decisions than creating tomorrow's value. Rather than treating it as an engineering problem to solve in isolation, leadership elevated it to a company-wide strategic initiative with a timeline (almost like a sprint).

Progress wasn't buried in an engineering dashboard. It became a standing topic at company all-hands meetings, creating visibility, accountability, and alignment across the business. Everyone understood the goal: free up more capacity for innovation, roadmap delivery, and customer value. Within six months, we had fundamentally changed the balance between maintaining the platform and building the future. That didn't happen because engineering worked harder. It happened because the company made platform health a strategic priority.

That experience reinforced an important lesson for me: technical debt isn't just an engineering discussion. It's a strategy discussion.

It's also one of those moments where great marketers stop thinking only as marketers and start thinking as business leaders. The best marketers understand that growth is influenced by far more than campaigns, content, and customer acquisition. It's shaped by the systems, processes, and decisions that determine whether a company can scale.

Technical debt is one of those decisions.

A Quick Word About AI

I recently joined a discussion among roughly 30 product leaders focused on AI. While the conversation covered everything from productivity to product innovation, one theme surfaced again and again: AI's potential to accelerate technical debt remediation.

AI isn't a silver bullet. In fact, applied carelessly, it can create new forms of complexity and technical debt of its own. But when targeted at the right problems (such as code analysis, refactoring, architecture reviews, documentation, testing, and modernization efforts), it can help organizations reduce the cost and effort required to improve platform health.

Will AI eliminate technical debt? No. But it can help organizations pay it down faster and more efficiently, creating more capacity for innovation, customer experience improvements, and growth.

The Bottom Line

As marketers, we're accountable for growth. But growth doesn't happen in a vacuum.

It depends on products that scale, systems that connect, data that flows, and customer experiences that build trust. That's why technical debt isn't just an engineering concern. Left unchecked, it eventually becomes growth debt.

The companies that scale successfully aren't always the ones with the most features or the fastest launches. They're the ones disciplined enough to invest in the foundations that make growth possible.

Because growth isn't just about creating demand. It's about creating the capacity to meet it.

And for something that impacts that capacity so directly, marketers don't talk about technical debt nearly enough.
