Gabe Newell

Career

While studying at Harvard, Gabe Newell went to see his brother at Microsoft, a company that wasn't yet a major force in software. Following advice from Microsoft executive Steve Ballmer, he left Harvard and joined the company, later describing it as the ideal place to learn programming at that time. Over 13 years, Newell worked as a programmer and technical executive, contributing to the first three versions of Windows. In 1995, he was struck by the fact that the game Doom was installed on more computers globally than Windows 95.

He called this a revelation, noting that id Software, a tiny team of 12, had achieved this without retail distribution. Newell then led a project to bring Doom to Windows 95, which helped establish Windows as a serious gaming platform. Inspired by Michael Abrash’s move to id Software for Quake, Newell and fellow Microsoft employee Mike Harrington founded Valve on August 24, 1996. Newell chose this over retiring because he thought collaborating with smart, motivated people to create products for millions would be more enjoyable.

They self-funded Valve’s first game, Half-Life (1998), which was both a critical and commercial hit. Harrington sold his share to Newell in 2000. For Half-Life 2 (2004), Newell gave the team no deadline and a nearly unlimited budget, even offering to cover costs himself. The company nearly went bankrupt during a legal fight with Vivendi Games, until an intern found an email showing Vivendi was destroying evidence.

Personal life

Newell formerly suffered from Fuchs' dystrophy, a congenital disease affecting the cornea, and was cured via two cornea transplants in 2006 and 2007. On the same day he founded Valve with Harrington, he married Lisa Mennet; they have two sons, the elder of whom, Gray, became a professional race car driver. The birth of Gray in the late 1990s inspired the final boss of Half-Life, as the couple considered childbirth the most frightening thing they could think of at the time.

Newell and Mennet divorced around 2016. In 2011, he said his favorite games included Super Mario 64, Doom, and a Burroughs mainframe version of the 1971 Star Trek game, the first game he ever played; Doom convinced him games were the future of entertainment, and Super Mario 64 convinced him games were art. He was a fan of the animated series My Little Pony: Friendship Is Magic. Within the gaming community, he has the nickname Gaben, derived from his work email address.

He said he tried to grow into his public image, noting that fans hug him in public and that he learned from customers. In 2018, he recorded a deadpan self-referential voice pack for Dota 2. During the COVID-19 pandemic, he stayed in Auckland, New Zealand, and helped arrange a free event, We Love Aotearoa, with live performances and VR stands for Valve games; he applied for permanent residency in New Zealand in October 2020 but had returned to Seattle by 2021.

He has owned and sold several homes in Seattle and has lived mostly at sea since the pandemic. In June 2026, he purchased a 20,000-square-foot mansion in Florida for $70.8 million. As of 2026, he had lost a substantial amount of weight.
