Our History

On May 15, 1851, MassMutual started with a single room and a single purpose—to help people protect their family and their future. Today, more than 160 years later, that single, long-term perspective remains core to all we do. We’re a company defined by our mutuality, operating for the benefit of our members and participating policyowners, and proud of our long history. Over time, we’ve provided financial and retirement security to millions of people and earned financial strength ratings1 that are among the highest of any company in any industry. Massmutual@work Whole Life certificate owners are eligible to receive dividends. While dividends are not guaranteed, MassMutual has paid them to eligible participating policyowners consistently since the 1860s.

Today, MassMutual ranks in the Fortune 5002 and was listed as one of the World's Most Ethical Companies by Ethisphere.3
