What my clients say
I’d spent years growing in my role, but struggled to articulate what really made me different. I knew I had value, but I didn’t know how to express it without sounding generic.
Working with GJ CONCEPTS helped me cut through the noise. Guylaine helped me name my strengths, define my tone, and communicate with clarity — both on paper and in meetings.
Brand Strategist, Paris
After nearly a decade in engineering, I wanted to transition into a more strategic product role — but I wasn’t sure how to reposition myself without starting from scratch.
Guylaine helped me build a clear value proposition based on my existing skills, refine how I speak about my experience, and gain the confidence to pursue the change.
Product Manager (former Engineer), Lyon
When I started working with Guylaine, I thought I knew what to expect, having experienced management training before. Spoiler alert, I had no idea!
She not only took me outside my comfort zone—sometimes even breaking down walls I didn’t even know needed breaking down—but she also revealed blind spots I didn’t know existed.
The Management Tone Program is truly tailor-made and designed to align with your personality and goals.
I can’t recommend Guylaine enough. Prepare yourself for revelations—sometimes the unexpected kind!
Finance CFO

Her direct approach and positive energy are invaluable. Thank you is not enough for the change you have helped me in my career.
I highly recommend her Leadership Identity program to any business leader looking to scale.

Guylaine’s management tone program was instrumental in elevating my skills. Her guidance was pivotal in achieving the superior level of performance expected of both myself and my team.
Implementing proven methodologies alongside her openness to exploring innovative strategies changed my approach to my role.
This partnership has not only been a game-changer in my professional journey, but also in how I perceive and tackle management challenges.
Management committee member, Geneva
Thanks to my sessions with Guylaine, I was able to understand the place that Art was going to take in my life, and be able to target the type of art I wanted to pursue better.
By investing in her leadership identity program, I avoided several years of wandering in my field.
