Currently probably one of the leading online impact measurement tools (in terms of number of customers and public visibility) in the category of impact measurements that a.) result in a score and b.) cover all major sustainability dimensions. The tool distinguishes between impact assessment, impact benchmark (where the results are compared to other, similar businesses) and improvement. Initial measurement is free. Participants can apply for a B-Corp label certification, that costs annually depending on company size between 500 USD to 25000 USD. Re-assessment is necessary every two years to keep B-Corp status. It now targets as well startups, that can apply for a pending B-Corp status. A strength is the fact that it gives clear ideas which outcomes may be important. Many of the criteria requested during the process address SMEs and corporates and some may be difficult to provide or less relevant for startups.
