As a laravel developer w/ the skills to build out a new app/mvp -- Bubble looks pretty awesome. I have a ton of MVP ideas but never get started because, while coding isn't difficult--the time level to code all the aspects is daunting when I have a 9-5 job to hold down too.

I could see myself using something like this for side project validation until they start gaining revenue, then I'd probably transition to something more solid and choose a framework that can scale properly. But for validation this looks pretty awesome.
