It's really hard to bring something like this to market as a smaller company trying to work with factories remotely. My handlebar project is/was also very hard. And cost more than I expected.
It's very possible that the principals behind the two companies are collaborating on the road bike, as Vanquish also has one coming and the list of people developing product for / doing technical work to support more Tri / TT influence in road bike fits is not large, and I get the sense that a lot of us have corresponded in one way or another at this point. It's unlikely they are using a large open mold factory, as a design like this is fairly risky, and the MOQs can make the capital outlay difficult to finance.
I believe Vanquish originally tried to build around the bike that became the Avenger Tm7, but there were problems, and the two parties walked away.
