AdAstra: POET's engine is designed into a customer's product that showed at the OFC.
QuantumScape has...? Their product isn't even out of the lab.
Important difference! But if you are far enough away and look at these companies from a distant (investor) perspective, both are pre-revenue and look “the same”.
Therefore, the valuation is unfair, but what can we or POET management do? Except progressing from pre-revenue to revenue, and I’m sure they are working on that, see the roadmap.
