The starting point

"I reached out to Executive Career Coaching after noticing a pattern of working multiple nights a week until 01:30 am."
"As a CTO, I am wearing multiple hats in a fast-scaling start-up that needs more structure and alignment to grow our company to the next level."

What we clarified in 12 sessions

  1. CEO and CTO

    Roles and responsibilities clarification between the CEO & CTO.

  2. Time and energy

    Time and energy audit, supported by a calendar scan.

  3. Leadership cadence

    Deployment of a high-performance leadership cadence.

In Michiel's words, from his review.

"What differentiates Executive Career Coaching from other coaches is the application of experience, not just theoretical frameworks, but knowing how to implement these, so they will sustain."
Michiel K, CTO
Our principle

When it's not in the calendar, it's not a priority.

With Michiel, every strategic decision was captured in the calendar. That level of granularity takes a leader from insight to application, and to results that last. We coach from experience, not theory.

  • InsightSee where your time and energy go today.
  • ApplicationEvery strategic decision gets a place in the calendar.
  • Sustained resultsA leadership cadence that keeps running after the program.

  • In our clients' words.

    I reached out to Executive Career Coaching after noticing a pattern of working multiple nights a week until 01:30 am.

    As a CTO, I am wearing multiple hats in a fast-scaling start-up that needs more structure and alignment to grow our company to the next level. In only 12 sessions, we clarified the following:

    1. Roles and responsibilities clarification between the CEO & CTO.
    2. Time and energy audit, supported by a calendar scan.
    3. Deployment of a high-performance leadership cadence.

    What differentiates Executive Career Coaching from other coaches is the application of experience, not just theoretical frameworks, but knowing how to implement these, so they will sustain.

    I highly recommend working with Executive Career Coaching for every leader who wants to work smarter, instead of harder.

    "

    Before starting the Executive Career Coaching Program, I felt overwhelmed and struggled to motivate my team with clarity. However, after completing 12 coaching sessions, I experienced a remarkable transformation. I regained my clarity, energy, and motivation to lead my team and business with the passion it deserves.

    The differentiation I experienced in this program is the practical application of coaching techniques within the flow of work, making the deployment truly impactful. This approach not only enhanced my leadership skills but also empowered me to inspire and drive my team effectively. I highly recommend this program to any executive seeking to elevate their leadership capabilities and achieve sustainable success.

    "

    After working 15 years for a multinational, I found myself repeatedly asking, "Is this it?" I considered entrepreneurship but didn't dare to take the leap, unsure of where to start.

    In just 90 days, Executive Career Coaching has been instrumental in supporting me structure my thoughts and work towards concrete opportunities.

    Their experience in building a company from the ground up, including developing a business proposition and identifying the necessary resources (people, skills, tools, and technologies), has been highly valuable.

    This guidance has given me the confidence and clarity to pursue my entrepreneurial ambitions. I highly recommend this program to anyone looking to transition from corporate life to entrepreneurship.
