“these two numbers cannot tell the whole story. And even together they don't take into account the largest expense item.”

Jellyfish's Head of AI R&D presents platform data showing AI spending rose 60x year-over-year while engineer PR throughput increased 43%, but argues token costs are misleading because developer salaries dwarf them as the true expense.

This reframes how engineering leaders should pitch AI budgets to CFOs and boards.
