Private Work

Confidential Neuro-Evolutionary Transformation

Confidential work for those who have built everything or are building boldly; yet feel the quiet cost of misalignment.

We help you dissolve hidden friction: over-functioning, disconnection, intensity-seeking, numbness, relational erosion, and the pressure of maintaining an image.

This is not therapy, and not coaching-as-usual.
It’s a precision process to restore inner alignment and build Sevenfold Wealth; a life rich in meaning, vitality, relationships, impact, and sustainable legacy, without losing your edge.

Discreet inside out coherence for individuals, families, and organizations. Designed to strengthen people, profit, and planet.

We align inner authority, relationships, and operations so Sevenfold Wealth becomes real in business and life.

For Companies

Operational Optimisation

We turn vision into repeatable excellence: roles, dashboards, and training that hold standards. We focus where most systems break, middle management, using tailored agile project management to build sevenfold wealth and legacy.

High Standards aren’t a promise.

They’re a method

The Sevenfold Wealth OS is our framework for inside out coherence.


Built for your stage of life and applied across five levels.
Individual. Family. Community. Organization. Planet.

“Self → Organization → World”

A global logistics leader published our collaboration

“We listened, we analysed, we brainstormed and we were creative. We came to an agreement that smart decision making comes through combining subjectivity with objectivity. By testing, proving, cross checking data, it became a real test to then confirm that the model can then determine strategic value, cost savings and operational efficiency.”

For Hospitality & Quality

Menu + Procurement + Supply chain + Service Standard

We map the chef’s art into operational reality: better sourcing, tighter prep, less waste, and stronger execution on the plate, so every world-class guest can taste the difference, every time

  • Visionary Founder & CEO

    I’m Perla Harriet Ernest with 15+ years across sectors specialising in human behaviour and communication.

    At fifteen, I asked myself a raw question: Why am I here, if I can’t even speak freely?
    That question became a decision.

    In 2009, I did the work; intensively, consistently, with full determination; because I knew communication was my first step to unlock everything in me: leadership, connection, and creation.

    As a multifaceted entrepreneur and executive, curiosity and connection have always been my compass.

    As founder & CEO of Proyecto Ernest, we build coherence: smart systems beyond tech, virtuous leadership with agile project management that delivers results, and communication that lands across diversity.

  • I grew up as an expat; a third-culture life across five continents, shaped by cultures, class dynamics, and hierarchy.

    I’ve worked and socialised across worlds; from working-class environments to executives, major company owners, and private circles.

    One constant stood out: human behaviour is fascinating uniquely & context-driven.

    Mindset, background, childhood conditioning, and environment shape how adults relate, lead, buy, trust, and collaborate across personal life, family, friendships, strangers and business .

    Which is why cross-cultural and niche differences aren’t a problem, but a roadmap: understand yourself - others, and you can build cohesion across People, Profit, and Planet.

  • After moving to Saint Barths, I saw how much excellence depends on design, not effort.

    I began spotting patterns across residents, seasonal teams, UHNW families, luxury travellers, and the curious ones who come to explore. One thing became undeniable: effort alone doesn’t hold standards, systems do.

    Island economics work differently than cities. Logistics are tighter, seasons hit harder, and pressure moves fast through teams. Geopolitical shifts can also change conditions quickly.

    When the nervous system of a business is overloaded, consistency breaks.

    Our work supports ambitious businesses and private clients with what actually sustains quality over time: clear processes, strong habits, and human-centred operations that create value today, set standards that last, and stay adaptable in a world that keeps moving. When standards are designed into how people lead, communicate, and operate, expectations stop being an illusion and become a repeatable reality.

    So we build standards that hold—without burning out the people behind the work, and with legacy in mind. Because growth without company-specific systems multiplies chaos: bottlenecks appear in operations, revenue, profit, team performance, client experience, and personal energy.
