Looks identical to the Velobuild GF-003 / TanTan Seraph GR-047, and also seems to be "inspired by" the Wilier Jena (geometry is the exact same).
Although confusingly, Velobuild says T800 carbon, whereas this and TanTan say T1000 carbon.
Only noticed as I've been considering the GF-003 for a few weeks now, mostly for endurance road / light gravel, though I haven't worked up to pulling the trigger yet.
On Velobuild's Instagram, they have one picture of someone who built out a GF-003:
