 For example, when looking to invest in a company that makes and distributes anti-malarial bed nets, Acumen uses numbers to measure the social impact of this company.This means that the more number of anti-malarial bed nets manufactured and distributed, the more impact the company made.If a company builds toilets and shower facilities in urban slums and business districts, the success of this is measured by the number of times the toilet and shower facilities are used.
