5 No-BS Leadership Lessons from Startup Founders & HR Leaders


Hi, Reader

What could a startup founder and a seasoned global HR leader have in common? As it turns out, quite a lot—especially when it comes to building great teams.

I recently spoke with Sebastian Gerhardt, Co-Founder & CEO Flea, and Simon Mulder, Executive Leader, Chief People Officer. Their perspectives were different, but their core lessons? Uncannily similar.

Here are five no-BS leadership and teamwork lessons straight from our conversations:


1. Open Communication is the Foundation of a Strong Team

Both emphasized that communication isn’t just important—it’s everything. In fast-moving environments, a lack of clarity creates friction, and when transparency is missing, confusion and frustration spread like wildfire.

✏️ Lesson: The best leaders listen more than they talk. Whether it’s structured surveys, regular feedback loops, or simply creating space for honest conversations, fostering open dialogue is non-negotiable.


2. Leadership Evolves—Not Everyone is Meant to Scale

Startup founders often struggle with scaling their leadership. The takeaway? Leadership at different stages of growth requires different skills, and not every great entrepreneur is destined to be a long-term CEO.

✏️ Lesson: Be self-aware. Know when to grow, when to evolve, and when to bring in someone else who’s better suited for the next stage.


3. Measure Outcomes, Not Just Output

Clarity and a productive environment matter far more than raw productivity metrics. Similarly, Simon’s M&A insights highlight that long-term strategy always beats short-term quick fixes.

✏️ Lesson: Focus on value creation. Don’t fall for vanity metrics—what matters is what truly moves the business forward.


4. Fear Kills Innovation, Curiosity Fuels Growth

Fear-driven leadership leads to bad decisions. Whether in M&A or navigating change, organizations that let fear dictate strategy tend to stagnate. Instead, the best teams and leaders cultivate curiosity—always seeking new ways to learn, grow, and improve.

✏️ Lesson: Encourage risk-taking. Create an environment where it’s safe to experiment and innovate.


5. Success is Built on Strategy, Not Shortcuts

Quick fixes are tempting, but they rarely work. Startups often patch problems instead of solving them systematically, and deals fall apart when they aren’t tied to a clear strategic vision.

✏️ Lesson: Slow down. Think long-term. The best leaders don’t build Band-Aids; they build systems.


These are real, battle-tested lessons—no fluff, no corporate jargon. And if you want more insights like these, make sure to subscribe to my YouTube channel, where I share interviews with top leaders who are in the trenches, figuring this stuff out in real time.

Hi Reader! According to MIT's State of AI in Business 2025 report, 80% of organizations are already using AI. And yet 95% are getting zero return on investment. I've been sitting with that number since November, when I started interviewing HR executives to understand what's actually happening inside organizations navigating AI transformation. Fifteen-plus conversations later — leaders across tech, financial services, healthcare, payroll, insurance, organizations from 150 to 220,000 employees...

Hi Reader! When I started as a manager, I loved it when people agreed with me. Oh no, I wasn't arrogant. At least, I didn't think so at the time. For me, it felt like confirmation. Like I was reading the room correctly, making good calls, earning trust. Then, a leadership program for a bank I'd invested real time and energy in failed. And in the aftermath, I found out that several people on my team had seen it coming. They'd had concerns. Real ones. And they hadn't said a word — because they...

Hi Reader, What is the most important leadership job right now? In my work with leaders, helping them build strong, engaged teams, I came to the conclusion that the most important leadership job today is to decrease complexity. Not accelerating adoption. Not even increasing capability. But reducing the noise. I was reminded of this in a recent conversation with Martin Beischl, VP of People and Culture, on the Built by People Leaders podcast. He shared his personal approach: "AI implemented in...
