Meet Rebeca, our founder
I’ve always been drawn to what makes us thrive — first through science, then through business, and ultimately through the conscious human experience.
I began my journey in the world of health — studying Nutrition and Pharmacy, working in hospitals, clinical trials, pharma industry and health tech organizations. I earned an Executive MBA from one of the world’s top international business schools and stepped into leadership roles across global health tech and life sciences.
From there, it accelerated. Fast.
I spent over two decades inside the engine rooms of healthcare and innovation— building, scaling, pushing.
Boardroom to airport. Presentation to pitch. Deal to deadline.
I lived on red-eye flights and back-to-back meetings, in a blur of quarterly forecasts and launch cycles.
I led global teams, built go-to-market strategies, and opened international markets across Europe, the U.S., and LATAM.
I negotiated with C-suites, partnered with investors, and built commercial engines that moved millions.
It was intense. Strategic. High-impact.
I made it work — across continents, across verticals, across time zones.
And the higher I climbed, the faster it went.
Until I couldn't feel the ground beneath my own feet anymore.
On paper, I was thriving.
But somewhere along the way, I had lost access to myself.
The further I climbed, the more I noticed a quiet cost — one we rarely name out loud.
Not just burnout.
Disconnection.
From my body. From my purpose. From coherence.
In 2022, I hit my edge. A full-body breakdown.
The kind of identity crisis that doesn’t care about your résumé.
Everything I had built on the outside no longer matched how I felt inside.
So I decided to find my way back.
With my breath. My biology. My nervous system. My limits. My truth. My fears. My shadows.
It wasn’t the decision itself that changed me — it was following through.
Doing the work. Living the discomfort.
And that changed everything: the way I lead, the way I live, and the way I guide others forward.
As part of that transformation, I went back to science — but this time, through the lens of the human experience.
I studied Neuroscience and Psychobiology, and I’m currently completing my ICF Coaching Certification, committed to guiding others with the same depth and integrity I asked of myself.
And I built 2040 Nanometers and State of Coherence for those who want to do the same — without stepping away from their leadership roles, but by redefining what real power looks and feels like.
At 2040 Nanometers, I blend neuroscience and bio-individual optimization to help founders and executives lead from a place of true coherence — not just strategy, but embodiment.
Because performance isn’t just what you do.
It’s how you show up.
And the future belongs to leaders who can hold complexity without collapsing, who can scale without self-sacrifice, and who choose to lead from within.
In flow, Rebeca.
"By harnessing the power of biohacking and nutritional supplements, I help individuals achieve optimal flow states—unlocking peak performance, enhancing creativity, and transforming leadership dynamics in conscious executive environments."
