PaveIQ looks pretty interesting. There has to be a big market of customers willing to hand over money to learn how their website is performing but aren't currently investing the time to learn GA's more advanced features or to learn how to mine insights from all that clickstream data.
I'm not so sure. There's a lot you get can from simply running basic analytics and an NPS survey. You should also be constantly talking with customers. Ideally you'd already know where the site/app is failing purely based on those interactions.
If they can pull in data from various sources (Stripe, SFIQ, etc), that's where this product could be really exciting.
