Got my first customer even before launch!

I was never expecting this!

I am working on my next product (and one of the most complex and challenging one I've ever made). It's a bot builder with a simple drag and drop UI. You can watch the video here: Botflow Teaser.

How I got my first customer is kind of strange. So what I did is I used my bot builder to launch a side project (Yah! even before launching the actual product). This was not intended to make money but just helping users to know if they have symptoms of Covid-19 and should/shouldn't go for the test. (yeah I launched it before Apple launched such a tool). Here it is: https://testcovid19.me/

So what happened is someone saw it on product hunt to actually have it on their portal and when we were talking I showed them the builder and they got interested in it. I never expected my first customer will come even before the launch.

By the way I am on track to launch it by May 10.
