UPDATE: CrunchBase have now restored their own documentation so you should now use the canonical information at http://developer.crunchbase.com/. I am leaving this here in case of existing links to it but it is of historical interest only.

NOTE: This documentation has been put here because I couldn't find it anywhere else. I am not associated with Crunchbase in any way. I cannot help you with your Crunchbase API problems. If you need help try here: https://groups.google.com/forum/#!forum/crunchbase-api

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
