PHYSIX OBSERVATION

A Meta veteran moving to a smaller company shows that AI infrastructure now outdraws the social giant in the competition for top finance talent. Fireworks' valuation could double within six months, but it just disclosed a credential leak in October, so balancing security against the pace of expansion will be the new CFO's first test.
