Our team uses a wide array of tools, including all of the ones you mention above and some homegrown solutions. Without them we never would have been able to put the focus on motion that we needed to in Material Design.

That said, there are still some huge problems designers face in trying to make software. Prototyping interaction and navigation, designing complex and interactive motion, getting our designs into code without losing fidelity, and even basic collaboration and version management. We’re serious about all these topics and we want to see how we can help make a world where a designer will never have to export a redline or have the wrong icon in the build ever again.
