Tell us about yourself

Mitchell Hashimoto
I'm a developer living in Los Angeles, CA. I previously co-founded HashiCorp.
Today I spend most of my time working on Ghostty, a new terminal emulator.
I was part of the initial engineering team behind most of the HashiCorp products, such as Vagrant, Packer, Consul, Terraform, Vault, Nomad, Waypoint, and more. I don't work on any of those projects anymore. I was CEO for ~4 years, CTO for ~5 years, an individual contributor for ~2 years, and then left the company in 2023.
I fly airplanes. ✈️ I'm an FAA licensed private pilot with an instrument rating (PPL ASEL IR). I currently fly a Cirrus SF50 Vision Jet. I frequently share pictures of my flights.

Mitchell, we're thrilled to have you on Open Source Friday to talk about vouch.

We can't wait to hear about what you're building and what drove you to create vouch.

Mitchell Hashimoto joins Open Source Friday to demo vouch, a trust management system for open source.
vouch makes trust explicit in a world where AI can generate lots of plausible but low quality contributions. Maintainers can vouch or denounce users, and enforce policies on issues and PRs using GitHub Actions and a simple VOUCHED.td file.
