Human Capital Sonar
Revealing hidden risks
Guiding to safer waters
Why do leading organisations need a Human Capital Sonar?
To cut turnover, boost commitment, and save costs!
Grouks helps organisations turn their training budgets into measurable investments in human capital. We design and deliver impactful programs on soft skills, leadership, stress management, and collective performance that create lasting organisational change.

Our unique approach combines science-based methodologies with real-time risk detection to reveal hidden signals such as burnout, disengagement, or conflict.
This predictive capability allows organisations to act early, strengthen resilience, and build robust, predictable teams before problems escalate.

From one-day transformative trainings to comprehensive long-term transformation journeys, Grouks ensures every action creates visible, measurable impact for individuals, teams, and executive boards. We bridge the gap between human development and business results.
Start With People - The Story Behind Grouks
Yves de Jamblinne's mission to change the world began with a simple observation: society was losing its common sense, and people were being pushed to the margins of business decisions. Determined to put humanity back at the center of solutions, he embarked on a transformational journey…
Today, Yves has found his way to change the world: helping organisations improve their performance by genuinely improving their people's lives and well-being.
At Grouks, this philosophy translates into one guiding principle: Start with people.
By listening to individuals, mapping their hidden challenges, and unlocking their strengths, we help organisations find clarity and resilience. Because when people thrive, performance follows naturally.
1
Early Career Foundation
Started in IT at a mutual insurance company, then joined Deloitte, bringing expertise in agile methods and change strategy. These experiences sparked crucial questions about how companies and society function.
2
The Pivot to People (2015)
Shifted focus from technology to human development. Became certified in NASA's Process Communication Model and neuroscience, founding Grouks Advisory as a trainer, coach, and change agent.
3
The Revelation (2019)
Recognized that training was often just "checkbox exercise" rather than strategic development. Began developing tools to objectively measure human risks within organizations.
4
The Validation (COVID)
The pandemic validated all initial hypotheses about human risk in organizations, accelerating development by a decade and proving the critical need for predictive human capital management.
5
Grouks Launch (2022)
After four years of development, partnered with experts to found Grouks. The tool can now predict burnouts and resignations up to 6 months in advance.
Why We Exist
People Are True Capital
We believe that people are the genuine capital of every organisation, not just another line item on the balance sheet. Human potential represents the greatest untapped resource in most companies today.
Training As Investment
Too often, training is treated as a necessary cost without clear return on investment. This outdated mindset wastes resources and misses opportunities for transformational growth.
Measurable Impact
Grouks exists to turn training expenses into measurable, lasting investments that strengthen resilience, enhance performance, and improve well-being across entire organisations with quantifiable results.
