Youform is a form builder which is an affordable Typeform alternative. 

We are building this since last two years and now successfully service 1000s of users.

Last week, we decided to conduct a Sean Ellis Test to understand our product market fit. 

We already have a 20,000+ registered users, but still we thought that finding the PMF with data backed by a proven test methodology won't harm. 

Sean Ellis, who coined the term "growth hacker" and was early growth in companies like Dropbox and Eventbrite devised this test. According to Sean Ellis test, you ask your users the following question: 

"How would you feel if you could no longer use the product?" and give them three options: 
- very disappointed,
- somewhat disappointed
- not disappointed at all. 

The findings of the test says that if at least 40% of your users respond with "very disappointed", then it's a strong signal for product market fit. 

Hence we used this test and obviously used Youform to create the survey. 

We added it on our dashboard and only showed it to the repeated users. We kept it for a week and after a week, almost 105 users responded to the survey. 

Our finding was that 64% of the responders said that they will be very disappointed. So if we go by Sean Ellis test, Youform has passed the product market fit survey.
