Vellum

Vellum is a platform for developing online ebooks with ease. In practice that means making developers faster with better editors, debuggers and workflows.

It makes the most sense for software teams. Alongside the main category they mention Developer Tools, EBooks and Service Industry. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Vellum is based in Long Island City, New York and founded in 2012. Their site is vellum.pub.

Our checklist for this category: language support, team features, and privacy of your code. Ask for a trial on your own data, not a canned demo.

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