I'll take this opportunity to point out a few things many companies get wrong when writing this kind of announcement:

• No images: images help a lot to understand what your product does at a glance. Especially if your audience is designers, making a good visual impact is extremely important.
• Inward-focused: half the post consists of thanking collaborators. That's great, but the average reader won't care. The second paragraph does explain what the product does, but that's only about 25% of the post about the product itself.
• Block-of-text syndrome: find the key marked "return" on your keyboard. Use it. Otherwise don't expect readers to actually read.
• No obvious call to action. I have to scoll all the way to the bottom of the post to find a link to the product, and since Medium links are also black it doesn't really stand out much.

If you're marketing something towards designers, I think it's super-important to give writing the same care as design itself. Otherwise, you won't stand a chance in a crowded market.

Seems a bit counterintuitive to have a platform for branding without the possibility to express Interface Interactions and motion.
