Leadership Lessons from Our Portfolio CEOs

Founders often look to investors, advisors, and peers for guidance – but some of the most powerful lessons come directly from the leaders building companies every day. Across the Blumberg Capital portfolio, CEOs continually share insights shaped by real experience: hiring, navigating uncertainty, developing teams, and learning how to lead through growth and change.

Their lessons reflect patterns we see again and again: success is built on alignment, honesty, humility, and a commitment to learning.

Spot A-Players Early and Compete for Them

“Hunting A-players for your startup is one of the hardest jobs you have as a founder. The best people already have jobs – well-paid ones, with equity and predictability. So how do you get them? 1. Spot them early….”
— Eldar Sadikov, Co-Founder and CEO of Field Materials AI, 2x founder (acq by PayPal ’18)

One of the most consistent challenges early-stage founders face is recruiting top talent. Eldar Sadikov’s insight gets straight to the heart of the issue: the people who will accelerate a startup’s trajectory are often already valued elsewhere.

His perspective emphasizes both difficulty and intentionality. Finding exceptional talent isn’t a passive process. It demands early identification and a founder’s commitment to pursuing people who will raise the bar for the entire organization. Even the brief excerpt included in the newsletter reflects a core truth: hiring well is strategic, competitive, and foundational.

It’s also a reminder that recruiting isn’t just about roles and responsibilities; it’s about recognizing potential before others see it, and building relationships that attract people to the mission long before they formally join.

Early Alignment Strengthens Every Relationship

“Deep alignment, honest communication, and a shared understanding of each other’s strengths and weaknesses will get you much further than anything else in the early stages.”
— Ron Arbel, Co-Founder and CEO at Aryon Security

Ron Arbel’s reflection highlights the value of alignment during the earliest phases of a company’s development. Startups are unpredictable, and the early team often sets the tone for how an organization operates under pressure.

His emphasis on strengths and weaknesses is particularly meaningful. Alignment isn’t about agreement; it’s about understanding. When teammates know how each person works, where they excel, and where they benefit from support, they can collaborate with clarity rather than assumption.

This kind of transparency builds trust quickly. It prevents miscommunication and ensures that momentum isn’t slowed by misunderstandings. For founders assembling their first or second cohort of hires, Ron’s perspective serves as a reminder that culture isn’t built later, rather it begins on day one.

Admitting Mistakes Changes the Pace of Progress

“When your whole team can genuinely admit mistakes and blind spots instead of defending themselves or reacting from fear, the pace at which you can pivot and improve changes everything.”
— Kathy M. Zhu, Co-Founder and CEO of Streamline AI

Kathy M. Zhu’s insight underscores one of the most valuable traits in fast-moving environments: psychological safety. When team members can acknowledge mistakes without fear, the organization becomes more adaptable.

Her reflection highlights a dynamic that founders know well: progress relies on iteration. Reacting defensively slows that process; acknowledging missteps accelerates it. The ability to pivot — to change course quickly and thoughtfully — becomes a competitive advantage.

At its core, this perspective is about creating a learning culture. Startups succeed when teams continuously refine their understanding, improve workflows, and make better decisions each time they encounter friction. Admitting mistakes isn’t a weakness; it’s the cornerstone of improvement.

Humility Is a Leadership Superpower

“Early in my journey, I realized something that changed everything: Admitting what you don’t know isn’t weakness. It’s your superpower as a leader (or aspiring one).”
— Irina Novoselsky, CEO of Hootsuite

Irina Novoselsky’s message reinforces a theme echoed by many founders and executives: humility strengthens leadership. In her reflection, admitting what you don’t know is not just a personal insight: it’s a strategic advantage.

Founders are often pressured to project certainty. Yet the reality of early-stage building is that uncertainty is everywhere — in the market, in product development, and in the internal team’s growth. Leaders who acknowledge what they don’t know create space for others to step in, contribute, and elevate the company’s overall decision-making.

Humility also fosters trust. Teams respond well to leaders who demonstrate openness and self-awareness, and who recognize that expertise can come from any corner of the organization. In fast-changing environments, that mindset encourages collaboration rather than hierarchy.

The Patterns Behind Leadership Wisdom

While each CEO brings a distinct voice and experience, the leadership lessons they share reveal recurring patterns:

1. Great teams are intentional teams.

Spotting A-players early and competing for them sets a strong foundation for execution. Talent doesn’t fall into place by accident — founders must be deliberate.

2. Alignment accelerates progress.

Understanding strengths, weaknesses, and communication styles reduces friction and creates cohesion during the most pivotal moments of a company’s journey.

3. Mistakes are a catalyst for improvement.

When teams can name challenges without fear, they iterate faster. Honest reflection leads to better solutions.

4. Humility invites contribution.

Leaders who acknowledge uncertainty make space for diverse ideas and stronger decisions. Learning becomes a shared responsibility rather than a top-down directive.

These themes appear across industries, roles, and stages of growth — underscoring that leadership isn’t defined by titles or milestones, but by mindsets and habits.

Why These Lessons Matter for Founders

Every founder eventually realizes that building a company is as much a leadership challenge as it is a product or market challenge. The insights shared by our portfolio CEOs, all rooted in firsthand experience, highlight the qualities that help teams navigate complexity and adapt to change.

These lessons also reflect a truth at the core of the founder journey: leadership maturity evolves over time. Whether it’s learning to hire differently, communicate more honestly, embrace mistakes, or ask for help, these shifts enable founders to build companies that are more resilient, more transparent, and ultimately more successful.

Startups move fast, and the demands on founders change quickly. But leadership principles like alignment, humility, and learning endure. They become the practices that enable teams to scale not just products, but trust, culture, and long-term ambition.
