Soul symbolizes emotion and empathy, and STEMrepresents science, objectivity, and analytical rigor.
It brings together two concepts that might seem mutually exclusive at first, but that we truly believe go hand in hand: blending the emotional with the rational, empathy with science, creativity with numbers.
We believe it’s in this intertwining that marketing thrives—and where we achieve the best results.
The essence of Soulstem didn’t come about by chance. It’s a true reflection of who I am: a chemist who discovered marketing as a way to make real transformation, beyond the lab.
As the founder of both the company and the brand, it felt only natural for Soulstem to carry pieces of my own story. I earned my degree in Chemistry from USP and spent five years working at Dow Chemical. After completing a postgraduate degree in Marketing at ESPM, I started freelancing and made Amsterdam my home for nearly five years—that’s where Soulstem was born.
In many ways, Soulstem carries my life’s journey, my inspirations, and all the lessons I’ve gathered along the way.
While Soulstem began as a personal journey, it has since grown into a collective of passionate professionals who share the same vision, aspirations, and high standards — all working together to make a meaningful impact on more brands and companies.
Over the years, however, Soulstem has grown. Today, it's a collaboration hub of partners passionate about:
Anyone responsible for a delivery here has gone through a careful selection process. We value partners who demonstrate expertise in their field, a strong drive to create something meaningful, and who share our quality standards.
We work with a limited number of clients because we believe that attention, personalization, and quality are essential to something we value deeply: long-term relationships.
You can think of us as an extension of your team — or even your marketing team itself. We adapt to your processes and ways of working to ensure that, together, we can achieve your company’s goals.
We measure the success of our partnerships in three ways:
The quality of our work, which must meet both our high standards and your expectations;
The trust we build, which fosters long-term partnerships;
The results and objectives we help your company reach.
What I value most about working with Soulstem is that the company was able to understand DOX's values and strengths, routinely offering suggestions for brand enhancement and other inbound marketing initiatives.

Working with Soulstem was an exceptional experience from start to finish. Their team took the time to truly understand our brand and helped us clarify our communication strategy in a way that felt authentic and aligned with our vision. They guided us through every step, from developing a compelling website communication plan to crafting website copy that truly resonates with our audience.
Their insights on how to translate that voice consistently across social media have also been invaluable. The process was professional, collaborative, and genuinely inspiring. I’d highly recommend Soulstem to anyone looking to elevate their brand presence with clarity and purpose.

We needed to update and recreate our website, and Soulstem has done a great job with assisting us. I cannot say enough about how happy we are with our new website. Leticia has been a dream to work with, and she has been informative, responsive, and more than patient with all our requests and questions.
I would recommend them to anyone who wishes to have a visually appealing and easy to navigate website. Thank you, Leticia, and Soulstem for more than exceeding our expectations!
