Well, with an established competitor like Sketch, you can laugh your way to the bank. SO many users pleaded their first born children to Sketch if they could have cross platform support, web-view support, real time collab, commenting system, cloud support, buit-in Developer handoff, nested components, auto-layouts - even just one of the above.

Sketch were nice and comfy and said NO to everything.

When you are coming into an established space, it must feel real good to have a competitor like that who gives away the full market to you kindly!
