History of Seagate

Founded: 1979
Founders: Alan Shugart, Douglas Mahon, Finis Conner

Seagate was founded in 1979 in Scotts Valley, California by Alan Shugart, Douglas Mahon and Finis Conner as Shugart Technology. The name referenced Shugart's earlier floppy disk company, but a trademark conflict forced the new venture to adopt the name Seagate Technology before shipping its first products.

Through the 1980s Seagate led the disk drive industry's migration from 5.25-inch to 3.5-inch form factors and built one of the most vertically integrated manufacturing operations in technology, producing its own heads, media and components. Acquisitions consolidated the market: it bought Control Data's Imprimis drive business in 1989, absorbed rival Conner Peripherals in 1996 (the firm founded by its own co-founder Finis Conner), and acquired Maxtor in 2005 to become the largest HDD maker by share.

An investor group took the company private in 2000 in a complex transaction tied to its stake in Veritas Software, and Seagate relisted in 2002. It reincorporated in Ireland in 2010 for tax efficiency and acquired LaCie in 2014. The 2020s brought a strategic pivot toward mass-capacity drives for cloud data centers and the rollout of HAMR technology through the Mozaic platform, positioning the brand for the AI data center era. Fiscal 2025 revenue hit $9.1 billion.
