About Us

We Turn Strategic Vision into Organizational Excellence

Where Strategy Meets Execution Through Organizational Development

The Strategic Challenge We Solve

Every leadership team knows this frustration: You have a brilliant strategy on paper, but it's not translating into results. Your teams are talented but misaligned. Your execution is inconsistent. Your organizational culture is blocking rather than enabling growth.

After 30+ years combined in venture capital, private equity, and operational leadership, we've seen this pattern repeatedly.

The gap between strategy and execution isn't a knowledge problem—it's an organizational development problem.

That's why we founded Leave a Mark: to bridge this critical gap through strategic organizational development that transforms how leadership teams operate, execute, and deliver results.

What Makes Us Different

Deep Operational DNA

We're not consultants who've only studied business—we've built, scaled, and transformed organizations from the inside. Our VC/PE/Corporate background means we understand what stakeholders expect and how to deliver it.

Strategic + Behavioral

We combine MBA-level strategic thinking with advanced organizational psychology (Tavistock methodology) to address both the rational and emotional dimensions of change.

Implementation Focus

We don't deliver PowerPoints and leave you alone. We work alongside your team through the entire journey, ensuring strategies become reality. Teaching you how to facilitate a long lasting change and have strategic discussions that create business impact

Measurable ROI

Every engagement includes clear objective and expected results. We measure success in business outcomes, not just workshop satisfaction scores.

What do we believe in:

Awareness comes from presence

We stay fully present and aware in each moment, allowing us to deeply understand our experiences and surroundings. This awareness guides our intuition and helps us create meaningful change.

Our word is sacred We stay true to ourselves and our purpose in every decision and action. We're honest, hold each other accountable, and never manipulate situations for personal gain.
We build to last by adapting

We adapt to changing conditions while staying true to our core purpose. We wear many hats comfortably, building solutions that last by evolving with the world around us.

Leaving a Mark in what you do Every interaction is an opportunity to make a positive impact. We strive to make each one count, knowing that every moment matters.
Learning happens together

We grow through constant learning and sharing with one another. We openly share our successes, failures, and lessons so everyone can benefit and improve together.

What Our Partners Say:

Sebastian Szlachtowski CEO @ Perfect Gym Solutions

💬

"Our strategy was previously undefined and not embedded within the organization. Leave a Mark provided us with a framework and process that enabled us to create a specific strategic document outlining the organization's priorities. As a result, our team knew exactly where to focus, making it much easier to achieve our business goals."

💬

"Thanks to our cooperation with Leave A Mark, we finally managed to remove the entire responsibility for strategy and execution from the executive board and distribute it evenly among middle management. We regained faith in the success of the changes we are implementing and commitment to intensive work in its implementation"

Krzysztof Łukaszuk CEO @ Hycom S. A.
