If you can find a way to enable collaboration (doesn't have to be realtime....but we don't want to use network shares, DropBox etc.....rather something more seamless - data stored in the cloud).
PipeDrive is for managing the sales funnel. I think we're using it like some people use Excel to write lists ie: we're not using the full capabilities. However, when one of our sales-people gave me a demo of PipeDrive, I then showed them HyperPlan - they almost fell off their seats. It has so way more capabilities. So, there is a niche landing page to think about. Also, it would really make managing our agile projects easier too.
HyperPlan has a lot of potential! Well done
