About The Success Studio
Hi, I’m Jomilsa Sousa, 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.
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 programs like Women in Customer Success, Catalyst and Tangent, I’ve seen the same pattern again and again; most asiring 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.
Who I work with
By the time people reach out, they’re usually dealing with one of these:
- They want to break into Customer Success or Account Management but don't know where to start
- They've just landed a CS or AM role and want to hit the ground running
- They're in the role but feeling reactive - busy but not strategic
- They want to have more confident commercial conversations
- They're ready to step into a more senior role but need support getting there.
This is where I come in.
My Approach
My coaching is 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 continue to grow long after our sessions end
Ready to move forward?
