1. Introduction to Market Growth

If you’ve ever tried to explain why your startup should enter a new vertical, or debated which industry to invest in next, you’ve probably stumbled over this one phrase: market growth.

It sounds straightforward. But like many buzzwords that get thrown around in boardrooms and budget meetings, it’s both overused and under-explained.

Understanding market growth isn’t just helpful—it’s foundational. It tells you where opportunity lives, how fast an industry is evolving, and whether your business strategy aligns with the external environment. For investors, it’s a key predictor of ROI. For founders and marketers, it can signal when to go all in or when to pivot.

In this article, we’ll break it all down—what market growth really means, how to measure it, and how to use it to make smarter decisions. And I’ll share some personal takeaways from nearly two decades of working across growth strategy, experimentation, and competitive positioning.

2. What is Market Growth?

Let’s start with the essentials.

Market growth refers to the increase in the overall size or value of a given market over a specific period of time. In simpler terms, it’s about more people buying, more money flowing, and more business potential opening up within a defined space.

But that growth can be shaped by many factors: innovation, demand shifts, accessibility, policy changes, or even changes in consumer sentiment. Growth isn’t always linear, and it’s definitely not automatic. A booming market today might plateau in 12 months if the underlying conditions shift.

When I work with companies through growth canvas sessions or experimentation sprints, market growth is one of the very first things I look at. If the market isn’t growing—or worse, it’s shrinking—it’s going to take more than good messaging to scale profitably.

What matters isn’t just whether a market is “big.” It’s whether it’s expanding in ways that support your business model. A large market with no growth is just a stagnating pool. A smaller one with accelerating adoption? That’s often a sweet spot for ROI-driven innovation.

3. How Market Growth is Measured

The temptation here is to overcomplicate it. I’ve seen pitch decks flooded with beautiful graphs that measure everything except what matters.

To keep things simple (which is one of my core values in growth consulting), here are the key metrics that actually reflect market growth:

• Revenue Increase: This is the total sales volume across all companies in the market. When that number goes up, the pie is getting bigger. 
• Sales Volume Growth: Sometimes the number of units sold increases even if prices fluctuate. This gives a sense of product demand. 
• Market Share Expansion: If your market share is increasing in a growing market, you’re capturing more of a bigger pie. That’s the sweet spot. 
• New Entrants: Yes, competition can be annoying, but new players entering a space often signal opportunity—especially if they’re well-funded or moving fast. 
• Customer Adoption Rates: Are more people using solutions in your category than they were a year ago? 

I typically advocate for focusing on 1–2 metrics that matter the most, rather than getting lost in reporting dashboards. Vanity metrics like impressions or vague “awareness” numbers may look impressive but rarely tell us anything actionable about growth.

If I’m launching a new product, I’d rather see early signs of real customer traction—purchases, signups with a credit card, or even locked-in pre-orders—than a million ad impressions with no conversions. The latter might feed your ego, but it won’t feed your bottom line.

4. Why Market Growth Matters

When you’re looking to invest, build, or grow, you’re betting on potential. Market growth is one of the few signals that helps reduce the uncertainty in those bets.

Here’s why it matters:

• Industry Vitality: A growing market indicates healthy demand. It’s a pulse check on whether a sector is evolving or flatlining. 
• Strategic Planning: Growth helps justify product development, team expansion, and go-to-market investments. No smart CEO greenlights a major initiative without some visibility into future returns. 
• Investor Confidence: If you’re raising capital, market growth figures are your best friends. They show that your startup isn’t swimming upstream against a declining current. 
• Benchmarking: Knowing how fast your market is growing helps you contextualize your own performance. Growing slower than the market? That’s a red flag. Growing faster? You’re doing something right. 

When I worked with a B2B SaaS platform that increased organic traffic tenfold in three years, we could have easily celebrated the SEO team. But what made the growth sustainable wasn’t just the marketing—it was the fact that the market itself was expanding rapidly (thanks to shifts in remote work and media delivery).

You can’t outrun a collapsing market with good execution alone. Growth has to be systemic.

5. How to Calculate Market Growth Rate

This part is more math than magic. But it’s critical.

The basic formula for calculating market growth rate is:

((Current Period Revenue – Previous Period Revenue) / Previous Period Revenue) x 100

Let’s say a market generated €1.2 billion last year and is on track to hit €1.5 billion this year. Here’s how it breaks down:

((1.5B – 1.2B) / 1.2B) x 100 = 25% market growth rate

That 25% tells you this isn’t just a healthy market—it’s accelerating. That’s when strategies like first-mover offers, viral growth loops, or MVP validation experiments become high-leverage.

A few tips on interpreting the results:

• A high growth rate signals urgency. Don’t over-plan. Move fast and iterate. 
• A low or negative rate doesn’t mean you should walk away, but it does mean you need a stronger moat (or a very contrarian thesis). 
• Always consider the baseline. 100% growth on a tiny base can still mean minimal impact in absolute terms
  

I’ve often recommended ROI-Driven Growth strategies specifically in these moments. When the market is ripe, the cost of waiting is opportunity lost. That’s when experimentation, even with imperfect data, can be the best teacher.

6. Factors That Influence Market Growth

Here’s the truth no spreadsheet will tell you: markets don’t grow in a vacuum. Growth is the result of layered, often unpredictable forces that shape how people behave, what they value, and how quickly they act on those values.

Over the years, I’ve seen markets explode (and sometimes implode) based on just one or two of the factors below. But when multiple forces converge? That’s when things really take off.

Let’s unpack them:

Consumer Behavior Trends

Sometimes, growth starts with a shift in what people want—or how they want it. Wellness didn’t become a multi-billion dollar industry overnight. It grew as people became more health-conscious, more tech-savvy, and more willing to spend on prevention rather than cure.

During my time leading growth strategies for a hybrid SaaS-consulting platform, we noticed spikes in customer acquisition every time we leaned into personalization and transparency. Why? Because the market was shifting toward authenticity. And if you’re tuned into those micro-trends early, you can build products that feel inevitable.

Economic Conditions and Policy Shifts

No founder loves talking about interest rates or regulatory updates. But ignoring them can cost you everything.

One of the most overlooked drivers of market growth is government policy. For example, renewable energy adoption surged not just because of innovation—but because of subsidies, incentives, and global agreements.

In past consulting engagements, I’ve advised companies to time their go-to-market strategy with anticipated regulation changes. It’s not about gaming the system—it’s about understanding the field you’re playing on.

Technological Innovations

This is the one everyone loves to talk about, but few truly prepare for.

Think of how generative AI shifted entire industries in a span of months. That kind of disruption can birth entirely new categories, and those categories become new markets.

In 2023, we launched 15+ AI tools internally to streamline growth ops. It wasn’t a gimmick—it was a response to a tectonic shift in the market. The lesson? Don’t just adopt technology. Watch how it reshapes your customer’s problems, expectations, and buying behavior.

Strategic Business Initiatives

Sometimes, markets grow because businesses lead the way. A well-positioned go-to-market motion or a bold pricing strategy can unlock demand that didn’t exist before.

I’ve worked on strategies where we didn’t wait for the market to “be ready.” Instead, we ran small, high-confidence experiments—like offering limited-time access to a feature that wasn’t yet part of our roadmap. If people paid for it, we built it. That kind of initiative doesn’t just serve demand. It helps shape it.

7. Real-World Examples of Market Growth

Let’s bring it down from theory to practice. Because some of the best lessons come from seeing how others navigated growth—or missed it.

Electric Vehicles (EVs)

A decade ago, EVs were niche. Tesla wasn’t yet the poster child, and charging stations were rare. Fast forward, and the EV market is growing at over 20% annually in many regions.

But what made the difference wasn’t just sleek design or Elon’s Twitter feed. It was a convergence of better battery tech, regulatory push, rising fuel costs, and a deepening cultural shift toward sustainability.

This is what I call a “stacked” market growth: multiple forces lining up to drive expansion. If you’re launching something in a similar environment, lean into timing. Ride the wave.

Streaming Services

Remember when Netflix used to mail DVDs? That feels like another lifetime.

The streaming boom didn’t just disrupt cable—it created a new media ecosystem. What started with one player opened doors for dozens more: from global giants to niche platforms focused on documentaries, anime, or even mindfulness.

And the growth didn’t stop at content. It spread to tech stacks (think bandwidth optimization), personalization engines, and production workflows. That’s the beauty of a growing market: it doesn’t just lift one boat. It builds an entirely new harbor.

Mature vs. Emerging Markets

Contrast that with mature markets like print newspapers or desktop software. Growth there is flat, sometimes even negative. But that’s not necessarily bad. These markets can be stable, profitable, and still worth serving—especially if you bring a fresh angle.

But if you’re looking for high-velocity opportunity, emerging markets are often where the energy is. Especially those at the intersection of tech and behavioral shifts (like digital health, remote education, or climate tech).

8. Final Thoughts on Market Growth

Market growth isn’t just a stat you sprinkle into your pitch deck. It’s a living indicator of where energy, money, and attention are moving.

Here’s what I’d leave you with:

• Use market growth as a directional compass, not just a retrospective report. 
• Remember that growth is rarely evenly distributed. Dig into the “why,” not just the “how much.” 
• Prioritize speed when you see growth accelerating. In a fast-growing market, timing often trumps perfection. 
• And when in doubt, experiment. The best way to validate whether a market is truly growing for your audience? Ask them to buy. Nothing clarifies faster than a transaction. 

If you’re navigating uncertain terrain or trying to decide whether your business fits into the future you’re betting on, this is the kind of work I do every day.

Whether through a Growth Canvas session, a series of ROI-driven experiments, or a tailored consulting engagement, I help teams make sense of markets—then move with clarity.

You don’t need more noise. You need signal.
