Draft:Mitchell Hashimoto

Mitchell Hashimoto is an American software engineer and entrepreneur. He co-founded HashiCorp with Armon Dadgar and is known for creating the open-source development-environment tool Vagrant, [1][2][3][4], Terraform and other notable open-source tools. He was HashiCorp's chief executive officer until 2016, later served as a chief technology officer, and left the company in 2023.[5][3]

Early life and education

Hashimoto grew up in Redondo Beach, California.[6] He received a Bachelor of Science degree in computer science from the University of Washington in 2011. Dadgar, his future co-founder, graduated from the same program that year.[4]

Career

Vagrant and HashiCorp

While working at a consulting firm during university, Hashimoto developed Vagrant to automate the configuration of client computers. The software reduced the associated setup time from about 15 hours to 15 minutes.[1] He and Dadgar founded HashiCorp in 2012, a year after graduating from the University of Washington.[4][2] Their university cloud-computing research was the company's origin, and HashiCorp later moved its headquarters from Seattle to San Francisco.[7]

Hashimoto was HashiCorp's CEO until 2016, when Dave McJannet became CEO and Hashimoto became co-CTO with Dadgar.[5][3][8] In 2021, he moved from the executive team and board to an individual-contributor engineering role, explaining that he wanted to return to full-time engineering work.[8][9] He departed HashiCorp in December 2023, after more than eleven years at the company.[5][3]

HashiCorp began trading on the Nasdaq in December 2021, at a valuation of more than $14 billion.[10][2] IBM completed its acquisition of HashiCorp for $6.4 billion in February 2025, after Hashimoto's departure from the company.[11]

Later work

After leaving HashiCorp, Hashimoto created a terminal emulator called Ghostty, primarily written in Zig, with native interfaces for macOS and Linux. Which garnered wide adoption and praise in the development community.[12] In February 2026, he introduced a system limiting contributions to vouched users in response to low-quality AI-assisted submissions to open-source projects.[13] In March 2026, he joined the board of directors of Vercel.[14] In 2024, Hashimoto and his wife pledged $300,000 to the Zig Software Foundation; in 2026, he announced a further $400,000 pledge, bringing their pledged support to $700,000.[15][16] In July 2026, he had co-founded Superlogical, which was developing a server-side terminal multiplexer using the libghostty software library.[17]

HashiCorp licensing dispute

In August 2023, HashiCorp changed the license for future releases of Terraform and other products from the Mozilla Public License 2.0 to the Business Source License. The decision prompted criticism and contributed to the OpenTofu fork, which joined the Linux Foundation.[18][19] The announcement was authored by Dadgar; Hashimoto had left HashiCorp's executive team and board in 2021, and no reliable source establishes a personal position by Hashimoto on the decision.[8]

Reception and recognition

Hashimoto and Dadgar were included in Forbes' 2017 30 Under 30 list for enterprise technology.[1]
