What I’ve Learned from Working with Dozens of High-Growth Founders

By Sapphire CFO Solutions

After almost three decades of working in finance and strategy—many of those years spent side-by-side with visionary founders—I’ve had the privilege of observing what makes high-growth leaders thrive. The startup world tends to mythologize founders as lone geniuses, but what I’ve found is that the most successful ones are not those who know everything from day one. They’re the ones who remain curious, decisive, and above all, adaptable.

Let’s start with a truth: building a company is hard. Founders are under relentless pressure. They're fundraising, building product, managing people, and trying to scale without losing their grip on the core business. In the midst of all that, finance often becomes an afterthought—until it’s not. And that’s where I often come in.

From financial services to SaaS to tech-enabled startups, I’ve had the opportunity to serve as a strategic partner to founders navigating critical inflection points. These experiences have given me a front-row seat to both avoidable pitfalls and inspiring breakthroughs.

The Best Founders Share Key Traits

While industries and business models vary, high-growth founders who succeed tend to share a few things in common:

• They ask questions fearlessly. They’re not afraid to admit what they don’t know—and seek expertise to fill the gaps.

  
  

• They value data over ego. Decisions are made based on evidence, not gut feel (or at least, not gut feel alone).

  
  

• They move fast but build thoughtfully. Urgency doesn’t replace structure. They know when to slow down and formalize processes.

  
  

• They invest early in systems. Whether it’s finance, ops, or compliance, they recognize that early investments in infrastructure create long-term flexibility.

  
  

I’ve also seen how founders who establish strong financial foundations early on are more likely to scale smoothly. That doesn’t mean hiring a full-time CFO on day one—but it does mean building a culture where financial clarity is non-negotiable.

What Often Goes Wrong

Unfortunately, not all founders take this approach. In the rush to grow, financial discipline is often sacrificed for speed. Here are some patterns I’ve seen repeatedly:

• Late-stage forecasting: Many companies wait until a board meeting or fundraising round to build a financial model, rather than using it as a planning tool.

  
  

• Cash blind spots: Founders don’t know their true burn rate, or they underestimate the time it takes to raise capital.

  
  

• Disconnected reporting: Financials are out of sync with operations, making it hard to spot red flags—or course-correct in time.

  
  

These gaps are rarely due to incompetence. They’re a natural byproduct of founders being stretched too thin. But they can have serious consequences: missed revenue targets, investor frustration, delayed raises, or even failed rounds.

How a Strategic CFO Can Help

The role of a CFO—especially a fractional one—isn’t just to produce reports. It’s to serve as a strategic guide. At Sapphire CFO Solutions, we act as an extension of the founder’s thought process. We ask the tough questions. We test assumptions. We bring calm to chaos.

Some of the most valuable support we offer includes:

• Building dynamic, driver-based forecasting models

  
  

• Creating board and investor-ready reporting

  
  

• Aligning pricing and go-to-market strategy with financial goals

  
  

• Improving cash flow visibility and scenario planning

  
  

• Supporting due diligence and fundraising narratives

  
  

But perhaps most importantly, we help founders lead with confidence. When you understand your financial runway, your margin dynamics, and your KPIs, you can make better decisions faster—and sleep better at night.

Final Takeaways

What I’ve learned from working with dozens of founders is this: ambition is important, but alignment is everything. Founders who bring finance into the strategy conversation early don’t just raise capital—they retain control. They don’t just survive—they scale with resilience.

If you’re building something great, don’t wait until it’s broken to bring in a financial partner. Get the support you need to unlock the next stage of growth—with clarity, confidence, and foresight.
