After this section, you would have gained the skills to validate your MVP. With the knowledge from this stage and after optimizing your product, you now know whether or not your solution or product is a product that people want.
At this point, there are 2 options you can take:
1. After optimizing the few parts of your product, you were able to increase the conversion rate, which also proves that your product is attractive enough that visitors want to become users. At this point, you have successfully validated your MVP. Congratulations! While you should never stop optimizing your Acitvation and Retention. However, now that we know that your product works, you can start growing your customers. Go on and learn some Growth Hacking!
2. You were just unable to convert the users. Your conversion rate is too low, and no matter what you do, your users just won't sign up. Even if they do sign up, they do not use any of the key activities. What's happening here is that you probably have a solution or a MVP that is not attractive enough for your target audience.
What we would suggest now is to go back to Customer Development to relearn about what your customers really want. Do not feel bad! Most companies pivot and succeed with a new tweaked solution. Or, you can email Ed so that we can bounce some ideas around.
