There is a famous quote that made Hercule Poirot even more famous than he already was, a quote that inspires us and motivates us in helping companies implement training solutions crafted on their personality and vision. “It is the brain, the little grey cells on which one must rely. One must seek the truth within–not without.” Greycells takes root in this quote and relies on focusing on every aspect, every connection and interaction from within a company for delivering tailor-made training solutions. We offer this by regarding the employees as the essential grey cells that make the brain (in this case the company) function properly, but in order for them to do that they must be first and then continuously properly trained.
