On Episode 4, we’re talking with David Cooperstein. He’s an independent marketing and strategy leader whose past clients include PebblePost, Adobe and Ascendant Network. David works with start up companies, including TVision Insights, SummitSync and Cuebiq, on marketing, positioning and strategic advice. I wanted to talk with David because he’s been a CMO and spent many years advising them when he was at Forrester. He knows what he’s talking about.
