While working on recruiting the next marketing head at Xobni (either VP or director level), I stumbled across a great blog post on the typical compensation packages for VPs of Marketing at Tech Startups: http://www.mikevolpe.com/bid/3858/.  I haven’t downloaded the actual report which may provide more data (you can see it here https://www.compstudy.com/).  

Unfortunately Mike’s post doesn’t give many details on compensation by startup stage (I assume these probably weren’t available in the report either).  In my opinion pre-series A has more risk and should give the marketing VP more equity (all other qualifications being equal).  Also 1% of a pre-series A company is worth much less than 1% of the same company after the series C round (because of dilution).
