I'm a Rails guy through and through, but I'll echo what many other commenters have said: stick with what you know. Trying out new frameworks, languagues, technology stacks, etc. is great for side projects. But if you're seriously trying to get a new startup product off the ground and to MVP status quickly, the last thing you need to worry about is the headache of dealing with all sorts of new technology puzzle pieces. At the end of the day, your users won't care if you coded the app in Ruby or Python or Javascript or Go. They'll care if the app is good and meets their needs.
