Blackbox

Blackbox is a global founder accelerator based in Silicon Valley. Put simply, it is about building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. Alongside the main category they mention Incubators. They are a very small team, 1 to 10 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Blackbox is based in San Francisco, California. You can read more at blackbox.org.

If you have worked with Blackbox, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
