Helsana AG, headquartered in Dübendorf, is a major Swiss health insurance company. The company claims to have 2.2 million customers insured and a revenue of 7.8 billion Swiss Francs, which would make it the largest health and accident insurer in Switzerland. The group employs approximately 3,400 people and has a Switzerland-wide network of 13 general agencies and 27 outlets.^[2]

The Group comprises three operational subsidiaries which are active in the fields of basic health, supplementary and casualty insurance. These operate under the names Helsana and Progrès as independent brands in the market. From 1 January 2017, Avanex was being merged with Helsana and Sansan with Progrès.^[3] Aerosana, another former subsidiary, merged on 1 January 2011 with Progrès.^[4]

The core business of the Helsana Group is basic insurance under the Swiss Health Insurance Act which generates around 70 percent of Helsana's total premium income.^{[citation needed]} The supplementary insurance division provides 27 percent of Helsana's income.

Helsana emerged in 1996 from the merger of two health and accident insurance companies, Helvetia and Artisana. Helvetia was founded in 1899, whilst Artisana was founded in 1952. Both were previously supported by a Swiss Verein, who today form the shareholders of Helsana. The Fondation Sana, formerly Stiftung Helvetia Sana and the successor of the Helvetia verein, hold 79 percent of the shares, whilst Artisana's verein holds 21 percent.^[5]
