CTO Coaching Without the BULLS?%t*.

Built teams. Scaled companies. Sold a startup. Now I coach technical leaders to lead like founders — not firefighters.

No fluff. Just results.

This Coaching Is Not for Everyone.

This is for you if…

  • You're leading a scaling tech org
  • You're facing serious leadership challenges
  • You're ready for direct, unfiltered feedback
  • You want to operate at a founder level

This is not for you if…

  • You want a motivational cheerleader
  • You need more productivity hacks
  • You’re not ready to be challenged
  • You just want to “get by” as CTO

What Happens During A Coaching Session?

In our weekly sessions, we will work on a wide range of different topics and challenges.

01

Weekly Fire-Fighting

We will discuss all issues and questions that you would collect during the week, always focussing on the whole company, not only Engineering. The topics could include, but are not limited to:

  • Stakeholder Management
  • Hiring
  • Team Management
  • Technology and Architecture
02

Personal Development

During our first sessions, we will determine where you want to develop yourself. This will become our guiding light. After all, coaching is also a mindset change and it i about you. I will constantly suggest articles and literature for direction. Reaching your personal goals is key to satisfaction and therefore key to high performance.

03

Team Development

Your team is never static, it grows and has a dynamic of its own. We will work on keeping your team motivated, fostering ownership and accountability among its members. Keep in mind that you are managing developers and they deserve to be developed.

1:1 Coaching That Drives Real Change

This isn’t a course or a checklist. This is a working relationship that changes how you lead.

Unfiltered Words from the People Who’ve Been There

Trusted by:

I’ve worked with Sebastian for over a year and can absolutely recommend him as a coach, mentor and sparring partner for technical leaders. His hands-on experience, pragmatic mindset and radical candor helped me a lot in continuously discovering new perspectives and making the right decisions!

Nikolai Gulatz

CTO & Managing Director at Instaffo

Sebastian is true technology visionier. He is able to turn most complex Engineering issues into set of pragmatic and comprehensive steps that make a venture journey simpler and more enjoyable.

I could only recommend Sebastian for any mission driven business at scale.

Sergiej Soft Rewiakin

Head of Tech at Caspar Health

I had the pleasure of working with Sebastian as my CTO coach, and I can confidently say that he is an invaluable asset to anyone looking to improve their leadership skills in a technology organization. Sebastian has an incredible ability to listen and provide thoughtful feedback that is tailored to your specific challenges.

During our coaching sessions, Sebastian provided me with valuable advice and validation of my thinking around management challenges, team structuring, and day-to-day work. His insights were always spot-on and helped me to better navigate complex situations with my team. Additionally, his guidance was always grounded in real-world experience, which made it all the more actionable and valuable.

Overall, I would highly recommend Sebastian to anyone looking to improve their leadership skills in a technology organization. His expertise, experience, and ability to tailor his coaching to your specific needs make him an invaluable asset to anyone looking to grow in their role.

Milko Slavov

CTO at TOKI

“The CTO coaching with Sebastian was very valuable for me. He's a "been-there-done-that" guy you can talk to about issues you face in your position as a technical leader.

We worked a lot together on team topologies, but also discussed detailed technical issues. He also provided personal insights and tried to take care of your personal well-being and growth during the sessions. I highly recommend working with him.”

Stafan Wagner

CTPO at Menlo79

Sebastian is an outstanding CTO and a popular speaker at international tech conferences.


More than that, he has the ability to listen, think, talk or execute - each at the right time and without compromise.


He knows how to motivate, empower and grow individuals and teams with his enthusiasm and energy. He creates an atmosphere of continuous learning, motivation, respect and fun.


I have learned so much about leadership from Seba, and it has been a pleasure working with him.

Johannes Pfeiffer

CTO at Kontist

Sebastian has been giving a course on leadership while I was working at Ageras. He does not only manage to present the information in a clear and entertaining way, but has a unique ability to engage the audience in deep conversations from which you come enriched and enlightened.

I felt he has an incredible balance of knowing his craft, being humble and at the same time having and expressing his own opinions based on his knowledge rather than what books would tell you.

I would definitely recommend Sebastian as a mentor/tutor/coach!

Mikhail Yaroshevskiy

Software Engineer at Booking.com

Sebastian is a great CTO and mentor. He is able to unite product and dev to achieve its best.

By constantly improving agile work process, he creates an atmosphere of real innovation.

He has the ability to break down complex matters to make them understandable for everybody.

It was great working together with him, and I owe him a lot. Would love to work with him again in the future.

Aaron Plantener

Lead Product Manager at Kontist

Sebastian is a brilliant and gifted technology leader who knows how to get the best out of people.

We worked together for several years in Kontist where he was both my boss and mentor. I had an opportunity to transition through several roles, from individual contributor to leadership and his support and guidance on this path have been instrumental.

Not only does he understand technology very well, but he is also great in passing the knowledge as well as building high performing teams. In addition to his professional expertise I find even more important his sense of humour, cheerful personality and in general a very positive attitude toward life and challenges. He is very approachable and full of experiences, always a pleasure to have a chat with him.

Sebastian is an ultimate tech leader and I would recommend him without a hesitation to any company or team.

Milos Nikolic

Engineering Manager at Emma

You don’t need another framework. You need a real challenge.

Why I Coach the Way I Do

My first boss bullied me. I swore I'd never feel powerless again.

I immigrated young, built and lost a startup, and then built again.

I coach CTOs because I’ve lived the chaos — and know how to lead through it.

Let’s talk. One call. Zero fluff.
