About The Success Studio

Hi, I’m Jomilsa, founder of The Success Studio.

I help Customer Success and Account Management professionals build their careers, grow their accounts and step into more senior roles with clarity and confidence.

My story

Why I created The Success Studio


I know what it’s like to step into a CS or AM role and feel both excited and unsure at the same time. When I first started, I didn’t have a clear roadmap. I had to figure things out by piecing together advice, testing frameworks and learning on the job.

Now, after 8+ years working in Customer Success and Account Management, and mentoring through programmes like Women in Customer Success, Catalyst and Tangent, I’ve seen the same pattern again and again: most aspiring and new CS and AM professionals don’t need more theory. They need practical guidance, confidence and someone in their corner.

That’s why I created The Success Studio.

My approach

Practical, not theoretical.


Every session is built around your real situation: your accounts, your conversations, your challenges. You won’t leave with a list of concepts. You’ll leave with a clear next step.

Clarity first

We start by getting clear on where you are today, where you want to go and what’s getting in the way.

Practical tools

Every session includes frameworks and templates you can use straight away.

Real-world focus

Grounded in 8+ years of hands-on CS and AM experience, not just theory.

Lasting progress

The skills and confidence you build keep growing long after our sessions end.

Global impact, local expertise

Supporting growth in 30+ countries

The Success Studio has partnered with professionals, teams and organisations across EMEA, North America and Asia, supporting growth, retention and success in over 30 countries. Every country in green represents a story of progress, from individual coaching wins to scaled CS transformations.
