In 2003 Congress authorized the creation of Health Savings Accounts (HSAs) to help consumers who have high deductible medical plans; today Americans hold $60 billion in 26 million HSAs and the Employee Benefits Research Institute estimates another 57 million could opt for them in the future; Lively is a new fintech firm focused on this space with an exclusively online administration; they now have $100 million in HSA assets and are looking to grow as more people switch to high deductible medical plans and become aware of the advantages of HSAs.
