Actually, Gong was the first manufacturer to have production SUPs worldwide in 2006: see
www.gong-galaxy.com/notre-histoire/However, since it is sold direct from France, hence the low price, you have drawbacks too compared to brands you find in physical shops: buying from other countries may have significant transport costs (200€ for sweden I think, you have to mail then for the Germany prices). Ff the board is damaged by transport, Gong can only offer paying for repairs + lost value, plus you dont get to try them before purchase like with a shop, unless you have some people with Gong boards nearby. This is why it is normal you may not heard of Gong out of France. (and may not want to buy one). Also, until recently Gong refused to advertise, and still refuse to appear in any cross-brands catalogs and tests.
This said, the Gong shaper is a longboarder at heart (doing contests when young) and had always proposed very innovative and original longboard SUP shapes... even if there were very, very few buyers (some models had less than 5 buyers). For instance, here he exposes - in French - the differences between the shape of 4 models of longboard SUPs
