I did. I built several apps and with my last one I raised personally a $1.2M seed investment with an european Venture Capital seed.

I studied design management and learnt how to build a tech team and lead them as a product manager.

I built these projects from the first prototypes, A/B tests, fund raising, user growth and traction based lean models.

The first step is: validate your app idea on the web before even building the app.

Contact me if you need all the details about the exact steps I followed, will be happy to help !
