My cofounder and I have downloaded and used over 20,000 web and mobile apps over the past ~800 days. This Guide will showcase some of our favorites--the ones we know can help you, as SAAS entrepreneurs/founders, be more productive.

For Non-Technical Founders (like me): Some of the apps in this Guide might seem somewhat abstract, or confusing. That's ok. With (a lot of) practice, plenty of mistakes and a willingness to fail you will come to see how useful these tools can be--both for freeing your mind of non-entrepreneurial tasks and/or speeding up the prototype to launch process and beyond.

For Technical Founders/Entrepreneurs: If I was technical, I'd recommend looking toward building a full stack company, as described by @chrisdixon.
