About Us

We believe that organizations are transformed by people

People4 is a boutique consultancy specializing in the development of people, teams, and organizations. We work with companies, public institutions, and non-profit organizations to turn talent into a real competitive advantage.

Our team is multicultural, multidisciplinary, and multigenerational. We operate across Europe, Latin America, and Africa, and have supported more than 1,000 executives in their professional growth journeys.

We didn't found People4 to do consulting.
We founded it because we believed it could be done better.

More than ever, business leaders face the need to combine strategy and science to deliver results. Most companies, even those with technologically advanced products and services, are still relatively new to using data-driven techniques to solve people-related challenges. We have been doing it for ten years.

We were born with a conviction: that the tools to understand people already existed, but that most consultancies were misusing them, oversimplifying them, or turning them into cosmetic exercises with no real impact. People4 applies social research techniques to business reality, something almost no one else does. We don't work on intuition or trends: we work with method, with data, and with the rigor of science applied to human behavior.

That is why we created our own tools. That is why the Sphere Method was born to support executive transitions, and SmartPeople4, a psychometric assessment platform with 95% predictive accuracy. That is why every intervention we deliver is measured, evaluated, and linked to business outcomes.

We are not a large consultancy. We don't want to be. We are a firm of senior professionals who choose their projects, who get deeply involved, and who never delegate to juniors what requires experience. Every client works directly with the person leading the project.

The person behind People4

Sandra Martín

A sociologist by training and a PhD in Political Science, with research focused on change management in organizations. That combination of a sociological perspective and academic rigor defines how People4 approaches every project: understanding the system first before intervening with people.

With over 25 years of experience working with executives, teams, and organizations across three continents, Sandra has led interventions for national governments, public institutions, multinational corporations, and international NGOs. From supporting executive transitions at IBEX-listed companies to designing people management models for ministries in Latin America.

Author of Sintoniza tu Equipo, creator of the Sphere Method, a structured program for supporting executive transitions, and of Leadershift Cards, a practical tool for leadership development. A regular speaker at leadership and talent management forums, and a guest lecturer on university executive programs. Firmly convinced that having a method for almost everything is useful: it gives you a map, even if you then have to adapt to the mountains.
