From Partner to Entrepreneur:
Your Guide to Ambition and Transformation
Iโm Mostyn, and Iโve walked both paths: the ambitious climb to leadership and the bold leap into reinvention. After years of focus, hard work, and building strong relationships, I became a partner at KPMG, one of the worldโs leading professional services firms. It was the culmination of two decades of persistence, strategic thinking, and personal growth. In addition to my client-facing role, I spent seven years as the COO and the Head of People of a major division of the firm.
But I didnโt stop there. I realised I wanted to redefine success for myself โ so I made the decision to leave the corporate world and build my own business. Today, I guide ambitious professionals and leaders like you to unlock their potential, whether youโre striving for the next big milestone or ready to chart an entirely new course.
Through my journey, Iโve mentored and coached hundreds of professionals โ from aspiring leaders to seasoned executives โ helping them achieve clarity, confidence, and results.
I know the questions running through your mind: Can I make it to the top? Is it worth the sacrifices? What if I want something completely different? These are the same questions Iโve faced โ and answered. The truth is, success looks different for everyone, but getting there requires clarity, confidence, and the right plan. Thatโs where I come in.
Whether youโre striving for your next big promotion or ready to pivot into something new, Atomic Ambition gives you the tools, support, and framework to succeed โ on your terms.
Letโs build your next chapter together.

How it works
10.5 hours of live interactive sessions, combining actionable frameworks, real-world case studies, and group discussions.
- 5 x 1.5 hour live Modules on Zoom:

- The purpose of these sessions is to keep your momentum and community support high, as you implement what you have decided.
- These are a combination of group coaching and Q&A.
- Community:
