"Creating human-first cultures"
10 years in Tech Ex-Criteo Certified coach First-time manager specialist 100% visio

Becoming a manager in Tech often means figuring it out as you go.

You are handed a team, a budget, responsibilities. And everyone expects you to naturally know how to motivate, delegate, give feedback, and make sense of it all.

You got a quick briefing. And if you ask questions, you worry about looking illegitimate in front of your peers or your own manager.

I have been there. And that is exactly why I created Hcode.

Even with a great manager, my impostor syndrome stopped me from asking questions. I wished I had someone neutral to help me step back and gain perspective.

Justine
Founder of Hcode · Coach & trainer

I spent 10 years in Tech, including several as a manager at Criteo. When I first stepped into a team lead role, I struggled with impostor syndrome. In a predominantly male environment, even with a great manager, I never dared to ask my questions.

I wish I had someone neutral to guide me. Today, that is exactly what I do for others.

This programme helped me strengthen my understanding of the management role, identify concrete levers for growth, and reflect on my own positioning. I particularly appreciated the interactive format, the practical cases and the group dynamic, which make the learnings very tangible.
