I'm currently using Insightera and have it integrated with Marketo.
The ability to segment our visitors in realtime is a very powerful tool. The integration, I believe, only lets gives us another switch-- based on a value in Marketo. What I'm really hoping to see is the inclusion of insightera data in Marketo/SFDC lead records. Things like industry and company size - determined ON the first visit would be great!
Imagine the new segmentations possible with all the data enrichment.
