I do know that consultants like to employ PhDs; it allows them to claim that they have extra skills that their clients do not, which is essential for consultancies to show. You might like to look into these areas.
The only issue is application and experience PHD or not. This is the whole global debate "Academia vs Experience". It all depends on how your pitching your Phd and to what. Tel me more about your expectations and goals. I maybe able to give you more advice My qualification is 37 years in the Life Science Industry (Pharmaceutical, Food and Healthcare), for example.
