An account on here which claims to be affiliated says "It's launching as a Kickstarter in September (disclaimer: I'm affiliated), and there is an offer for early-backers here https://get.gouach.com/2 for a 33% discount on the shipping price!"

This is our launch page in preparation for a Kickstarter in September

The difference with most Kickstarters is that we have ALREADY built the product, so it’s totally de-risked

We are using a kickstarter because we are a small startup and we don’t have the funds to buy the materials to build the batteries in advance, so the economics of the kickstarter (people pay us upfront) makes it possible for us to build a large batch at a lower cost!
