I don't think the Speeder is the same at the Hygge.
Back in the day there were only 2-3 carbon factories selling open molds. Flybike is one that still exists and seem to sell primarily through Carbonda. There was a factory called Gotobike which owns or owned the trademark for the Winspace name. Make what you will of that--but trying untangle who makes what frame and who designed what is, in my opinion not that useful. The relevant thing is whether or not you trust the brand to work with you and whether or not you think the combination of product quality and support will meet your needs.
What i do know is that I've been really happy with Speeder sourced parts and they sell a lot of parts, particularly forks. If I were to look for a partner to coordinate manufacturing and finalize design for a carbon bike part, Speeder would be part of the first outreach. However, they are primarily going to be more of a B2B type transaction while Tavelo appears to be investing quite a bit into the people and infrastructure to support consumers.
I have no idea if Speeder make their own bikes, their business arrangement with the factory or even if the frames and other parts come from the same factory. I THINK their new bike looks like an Adapt design and other than a bit more tire clearance and the bb86 spec looks pretty nice.
