About us


My name is Mathilde (aka Mattie), founder of Zest Ambition and certified Career Happiness Coach. Zest Ambition's mission is to create a society of happy, conscious and inspired professionals.

I use a blend of coaching, mentoring and positive psychology techniques to help clients find ways to make their career energising and motivating.

I created the career R.I.S.I.N.G methodology to accelerate the impact of my client interactions. I work with professionals, entrepreneurs, aspiring entrepreneurs and career changers. Whether you want to grow your confidence, learn to set healthy boundaries, develop a positive mindset, create routines to boost your performance and/or calibrate your ideas to write the best yet chapter in your career, I'm here to help.

My style is gentle and holistic. In every client relationship, I endeavour to strike a balance between empathy, challenge and encouragement. I have been employed, self-employed and an entrepreneur. Over the past decade, I have worked in start-ups and for big corporations, in the UK and abroad, which gives me a great deal of experience and exposure to multiple working environment and allows me to connect faster and deeper with the goals and situations clients bring to our sessions.

Here are a few big themes that come back for almost every single one of my clients: mindset, self-doubts, procrastination, time management, productivity, balance and wellbeing.

If you feel like I might be a good fit for you, please get in touch. I'd love to discuss how I can best support you.

A bit about me...

I have over a decade of experience helping businesses from start ups to big corporations expand their online presence. I have been employed, self-employed and I am now a fulfilled entrepreneur. I've worked in four different countries and managed teams spread out across the globe.

So far, my career has given me the chance (that's how I see it now, at least!) to experience the highs and lows of the corporate, start-up and entrepreneur worlds, the good and bad of a working from home life, the feelings of being unstoppable but also the overwhelming periods of doubts, work exhaustion and feeling stuck. I have been through numerous phases of questioning about my purpose, my career success, the meaning of work. I went through a number career transitions who led me to the become the fulfilled mum, wife, friend and entrepreneur that I am today.

I am on a mission to help individuals around the world feel inspired, valued and fulfilled in their professional life.

To do so, I use science-based methodologies, tools and transformational activities to help turn a bad day, week, month or year(s) into opportunities for a happy and thriving future.

I look forward to personalising what I have learned to your circumstances so that you too, can take your Career Happiness to the next level.
