WHAT OUR CLIENTS SAY ABOUT US

Marianne opened the eyes of our female webdevelopers, regarding personal strength, presence, self-confidence. It was empowering for our students to see how driven Marianne is as a professional, and how accessible and open she is when it comes to sharing experiences.

I am proud that I participated in the first round of the Yellow Program for Women in Tech. What I liked especially is how each of us in the group with different backgrounds got her own favor of enrichment and learning.
Laura Grau
Laura Grau
Director Of Engineering, NEW WORK SE
With the Women in Tech program from Yellow, I have learnt how to be more confident about myself in situations like negotiations, dealing with conflicts and making my opinions being heard in meetings. Doing this together with a group of women in a similar position, helped me to achieve my goals in an open and safe space.

The teambuilding training was engaging, thought provoking, and fun. It was a great experience and some even stated it was the best team building exercise they have attended. The training strengthened the bonds with our colleagues and showed us areas where we could improve as well.

I recommend Marianne to anyone who wants to have a clear view on personal changes they can make to function in a competitive, stressful environment. Her 'down to eart' analyses will enable you to change perspective; on yourself and on the situation at hand. You will be amazed how quickly you see the results.

Marianne knows how to connect to her audience. She uses clear examples and shares her wide experience in a way that keeps the audience mesmerised. She is one solid example of teaching with the right doses of theory, practice and fine sense of humor.

My team has grown bigger, stronger and more reliable. I have not lost any single member instead got many more, and they help me to inspire the others to share what we learned with Marianne. I definitely recommend her personally, and surely will ask for her help again in the near future. I got to know Marianne when I was leading a global virtual team of IT Security Specialists. We were having a technical workshop in Barcelona and two intensive sessions with Marianne, with the aims:  1. Ensure that the team knows, understands and overcomes communication challenges; 2. Using the differences to enable the team for success breaching silos; 3. Help team members to become brothers in arms (engage, act, support and deliver as one team, one voice). This was several years back and they are still delivering success.
