Below are the best resources I’m aware of for some of the various needs of startups. Many of these are development resources such as hosting, and website and application templates, but there are also asset resources, such as the best places to find (free!) stock photography, fonts, email templates and more. You’ll also find indispensable tools for building email lists, and more.
This list has a strong emphasis on easy-to-use, and affordability. In building a Lean Startup, we need tools to help us be more effecient and more effective, not depleting our cash.
