FretPen

FretPen offers users a portable guitar learning platform that allows users to learn on the go. In practice that means making developers faster with better editors, debuggers and workflows.

It makes the most sense for software teams. Related areas on their profile: Developer Tools, Hardware, Mobile and Music. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

FretPen is based in Avon, Colorado. More on fretpen.com.
