Strategic stock investing for Wealth Managers and Family Offices.

Wealth preservation is essential. 

But true financial stewardship requires strategic growth—built on conviction, discipline, and risk management.

Many wealth managers and family offices struggle to find stock investment strategies that deliver superior returns without unnecessary complexity. Our approach bridges that gap.

I’m Marcello, a former doctor turned full-time investor with two decades of experience in stock and crypto markets. 

Since 2016, I have worked with wealth managers, family offices, and high-net-worth individuals to implement investment strategies that maximize performance while protecting capital.

In 2020 and 2021, my momentum-based approach transformed $32,000 into over $1 million. 

Today, we refine and apply that strategy for professionals seeking an edge in the markets.

What we offer: 

↳ Institutional-grade stock strategies designed for long-term performance
↳ Risk-managed investment frameworks to navigate uncertainty with confidence
↳ Tailored solutions for wealth managers and family offices seeking scalable, high-conviction strategies

What catches my eye the most in the financial market this early in the year is the array of thriving sectors like gold and other metals, copper, memory, electricity, and so on, whereas the S&P 500 kicked off slowly. Unlike the previous years, I think this will be one where effective stock picking matters more than it has.

Mental Resilience + Mindfulness for Corporate | Neuroscientist | WHO Fides Member

Hi! I’m Anne-Sophie 👋🏽, a neuroscientist.

Over the past 12 years, I’ve dedicated my career to understanding how the brain works and how we can leverage that knowledge to improve focus, resilience, and performance. With 6 years in academia and 6 years in industry, I’ve built a unique approach that combines cutting-edge neuroscience with practical strategies to help individuals and teams thrive.

I run mental fitness and performance workshops for organisations that want to invest in their people. My mission is to create workplaces where employees feel focused, motivated, and supported. 

Happy, resilient teams are the foundation of success.

It’s incredibly rewarding to see the transformation in teams I’ve worked with:

✨ Employees who feel inspired and equipped with tools to handle challenges
✨ Leaders who foster environments of productivity and innovation
✨ Organisations that experience measurable boosts in engagement and retention

I wasn’t always confident about bringing my expertise outside the lab. Like many academics, I worried about how to translate complex science into actionable advice. But over time working in health tech startups, I’ve honed my ability to connect the dots between research and real-world impact, delivering workshops that are both engaging and results-driven.

Here’s how it’s paid off:

Teams leave my workshops with strategies they can apply immediately.
I’ve had the privilege of working with high-performing teams across different industries.
My sessions consistently receive feedback about being inspiring, practical, and grounded in real science.

Now, I have two core missions in my work:

1️⃣ To empower individuals and teams with neuroscience-backed tools to be the best they can be- to improve focus, resilience, and performance.
2️⃣ To bridge the gap between academic research and actionable insights, making science accessible and impactful for organisations.

If you’re a leader or organisation looking to:
✔️ Boost team productivity and mental fitness
✔️ Reduce burnout and improve employee well-being
✔️ Cultivate a resilient, focused workforce

I’d love to help.

Here’s how we can work together:

1️⃣ Book a workshop
2️⃣ Connect with me for speaking opportunities
3️⃣ Follow along for weekly tips and insights, on LinkedIn and through my Newsletter
