In the more than 170 years since MassMutual was founded — through profound social and economic change — one thing that has not wavered is our purpose: we help people secure their future and protect the ones they love.

Our focus on mutuality and longevity goes hand-in-hand with our commitment to sustainability.

Sustainability and Mutuality

As a mutual company, we operate for the benefit of our members and participating policyowners, which allows us to manage the company with a focus on their long-term interests. The actions we take to embed sustainability into our business are all in support of our commitment to provide lasting value to our policyowners, customers, employees, and communities.

Today, we take the same sense of stewardship to heart, knowing that the choices we make now will help us fulfill our obligations to all our stakeholders and create a better, more sustainable world for generations to come.”
