If you assume women pick companies based on diversity programmes and not the usual reasons people pick companies like needing a job, finding the problem interesting, good compensation, etc then yeah.
But unless that "aggressive programme" is illegally benefiting women with something concrete, like more pay, easier interviews or special privileges unavailable to men, it's like that the programme will be focused on trying to attract women into the profession who aren't already developers. So it'd make no difference to this hypothetical new college grad.
And if it did, then why would you want an employee whose primary reason for joining your startup over a competitor was the existence of a diversity programme? They'll just seem low energy compared to the men who joined because they love online discussions or whatever it is your firm does. Better pass and keep looking.
