Hi!, I've just launched the beta of my first startup.
Its called Wideo, and its a very intuitive, easy and free on line tool to create animated videos.

You can ask for a beta acces to agus@wideo.co or founders@wideo.co

I hope you find it useful!
I think its very interesting to use in demo startups videos, education, or just for fun
