Business Startup Checklist: 45 Steps to Build the Perfect Startup

Building a startup is not an easy task. It’s challenging and hard-work. During the last 20 years, plenty of startups saw the light, and we can see patterns to emerge.

People who grew their startups to billion dollars companies mainly followed the same process. This article is about to give you the key to success in order to build your startup from scratch.

Don’t get me wrong. Success is hard work. However, if you follow each of the following steps thoroughly and verify milestones often, you’ll build a successful company.

Milestones to Success

Your road to success is punctuated by 3 main milestones: Product / Market Fit, Transition to Growth, and finally Growth. The main aim is to:

  1. Get the product right
  2. Market this product
  3. Grow your business

Keep in mind that different types of startups, lead to different kind of execution. You might therefore have to adapt the checklist to your own needs.
