ETSS AG is an EMPA-ETH Domain Spin-Off and Swiss research and consulting company in the field of probability and variability analytics, strategy consulting, environment and health.

Our passion lies in risk research and engineering. Our services include, technology assessment, statistical and game-theoretic decision support as well as material flow analysis, external peer review, quality assurance and project management.

Do you think in scenarios? We compute these, a thousand times, a million times. Gain in knowledge is guaranteed!

Our expertise helps companies and institutions make safer decisions. We more broadly capture uncertainties and ambiguities by making them quantifiable with statistical methods.

We rely on many years of experience and on a network of specialized partners in other public and private institutions/companies in Europe and worldwide.

We operate in the commercial sector, we do not offer academic support.
