After watching Vice Media descend into bankruptcy this spring, a group of journalists from its popular tech brand, Motherboard, decided that the best way to do their work in a financially sustainable way was to strike out on their own.

And so 404 Media was born. The tech publication — founded by Motherboard’s former editor in chief, Jason Koebler; two of its top editors, Emanuel Maiberg and Samantha Cole; and one of its writers, Joseph Cox — started publishing on Tuesday.

Mr. Maiberg said 404 Media would start with just the four of them and focus on topics they had extensive experience reporting on, including hacking, sex work, niche online communities and the “right to repair” movement.

“It’s very much a website by humans for humans about technology,” he said. “It’s not about the business of technology — it’s about how it impacts real people in the real world.”
